DARPA Is Researching Quantized Inertia, a Theory Many Think Is Pseudoscience (vice.com)

dmoberhaus writes: DARPA just awarded a $1.3 million contract to an international team of researchers to study quantized inertia or QI. This is a controversial theory that many physicists think is pseudoscience, but according to the physicist that created it, QI may be the foundation for light-powered space travel that could open the door for interstellar travel. Motherboard looks at the fact and fiction of QI, its relationship to the 'impossible' EmDrive being developed by NASA and how these physicists are going to create experimental light-powered engines.

Quantized inertia (QI) is an alternative theory of inertia, a property of matter that describes an object's resistance to acceleration. QI was first proposed by University of Plymouth physicist Mike McCulloch in 2007, but it is still considered a fringe theory by many, if not most, physicists today. McCulloch has used the theory to explain galactic rotation speeds without the need for dark matter, but he believes it may one day provide the foundation for launching space vehicles without fuel. The DARPA grant will allow McCulloch and a team of collaborators from Germany and Spain to undertake a series of experiments that will apply QI in a laboratory setting for the first time.

Isn't this how science works?

[Bradmont]

So this is the first time I've heard of Quantized Inertia, but isn't this how science works? Somebody proposes a theory, and then they test it to see if it's bunk or not? Has it been tested before? If not, then why label it pseudoscience? Because it disagrees with current theories? Ok, so test it and prove it wrong...

Re:Isn't this how science works?

[Anonymous Coward]

Yes. And particularly when QM makes little sense and doesn't fit with other necessary theories. It's not like we've figured everything out already. We might end up chucking every major current theory in the wastebin inside a hundred years. My only objection here is that they put the proponent on the task. Perhaps he's indispensable right now, but then the funding should include replication by a separate, skeptical team.

I think in general with this type of thing, the fear is that their attempt to explain existing unexplained phenomena by disproving existing proven physical laws will become a giant boondoggle when the money could be better spent chasing more plausible but less obvious explanations that don't defy the entire groundwork of modern science.

It's exactly how science works. As soon as commonly held science fact is disproven, then it resets things and the scientific method starts all over again. That makes some comfortable people, uncomfortable.

Re:Isn't this how science works?

[bluefoxlucid]

I'm not so certain. Dark matter never panned out, and the information out there seems well-reasoned.

This looks like a new model, more like fringe science: might be bullshit, might be legitimate, but appears to be based in something that makes sense of things that don't make sense right now. It uses existing theories to suggest new behaviors within the framework of those theories.

By contrast, dark matter looks at the same problem--centrifugal forces should overcome the gravity of galaxies and hurl their stars out into space, but don't--and suggests that there's a magical, undiscovered form of matter which we can't measure, accounting for 85% of all mass and 25% of all energy in the universe. This creates new gravity (which we can't quite measure, apparently) so the universe doesn't break apart. We can't see it, we can't find it, we can't interact with it, but it's there because things happen that shouldn't happen.

Dark matter sounds a lot like the invisible ether medium that carries light. QI sounds like an insight about applying existing theories in ways that their frameworks suggest would work.

Now I am not a quantum physicist, so how am I to determine which of these is correct and which is coke-fueled magical thinking?

Re:Isn't this how science works?

[taylorius]

It's possible that this could be a step forward, you know. Just because dark matter / string theory et. al. have a lot of resources behind them in 2018, it doesn't mean they are the best explanation of the universe we can ever hope to have.

This is quantum question, so both cats are correct and coke-fueled at the same time when one of them opens up the box where you are inside.

That said, the pursuit of wacky theories often leads to the discovery of unintentional, very interesting other things.

So let's let them have a go with Quantum Inertia in their lab . . . as long as the Earth doesn't slip a disc in the process.

Re:Isn't this how science works?

[mysidia]

You are correct.... pseudoscience in this case is a pejorative --- they're calling it pseudo to try and make people think of it like Astrology or Tarot Reading pseudoscience, Not because it isn't science, not because it can't be tested --- not because those theorizing it don't intend for it to be tested, but simply because they're in the group of physicists who has some groupthink, satisfied in what their theories look like so far, and they think this relatively new theory must be wrong --- the physicists are proud of this thing they've contrived that would no longer be necessary.

The article says it all:

Against claims that he is theorizing about pseudoscience, McCulloch argues that it is the physicists invoking dark matter who “have been on the slide into pseudoscience for decades” and that “the only reason the dark matterist haven’t noticed is they are all happily going down together, so self-correction has become impossible.” He points to 17 papers in which he uses QI to make accurate predictions without the need for constant adjustment that are often found in theories of dark matter.

Re:Isn't this how science works?

[mysidia]

their attempt to explain existing unexplained phenomena by disproving existing proven physical laws will become a giant boondoggle

That's not how any of this works; and never should we be concerned about science that will challenge laws ---
disproving or challenging physical laws are the mark of advancement in the basic science.... physical laws are very well known to work and ultimately won't be "destroyed"
making a boondoggle, but the explanation of a physical law can change, and corrections can be required
for some situations. For example, General Relativity fundamentally changed our view of what Gravity is
(Curvature of space-time, not a force), and opened up a
huge world we were missing before; technically by invalidating Newton's Laws of motion in the process.

But despite that, Newton's Laws are frequently used; work fine in the vast majority of situations, and we
understand where they don't, and which physical model to use instead when they don't.

But we don't find out unless we test.

From TFA, it seems Dark Matter has as much evidence backing it as does QI

Re:Isn't this how science works?

[Anonymous Coward]

meh. This (QI) sounds a lot like Modified Newtonian dynamics (aka MOND). I've never heard of QI before, but I had a passing interest in MOND a while back. There are a number of problems that MOND solves. And there are a number of ways to test it, e.g. "Radial Acceleration Relation of CDM Satellite Galaxies" DOI: 10.1103/PhysRevLett.120.261301 . There's a recent article in Physical Review Letters, so you know it's not entirely baloney. The problem is, it solves problems in such a way it introduces more problems, like, not accounting for general relativity in general. So, while it may have some merit, it can't really stand on it's own as a theory, so practicing physicists don't really have any reason to take it seriously, especially since there are already better, less hacky tools for the work their doing. It might have some value one day when it's cleaned up a bit, but until then it's just barely better than pseudoscience.

Re:Isn't this how science works?

[Falconnan]

That QM makes little sense or doesn't fit other theories is irrelevant. That it makes predictions that are verifiable makes it a scientific theory. That those predictions are as close to perfect as they are (barring the Vacuum Catastrophe) makes it a pretty solid theory, though yes, incomplete. Further, it is no more likely to be discarded than Newton's laws of gravity in that it is a pretty good approximation for most purposes. So, unless a more accurate theory later arises which is easier to work with, it won't go away.

Your thoughts about replication are utterly irrefutable, however. As for pseudoscience allegations, if it's testable it's real science, even if the hypothesis is eventually excluded.

Re:Isn't this how science works?

[Ol Olsoc]

but simply because they're in the group of physicists who has some groupthink, satisfied in what their theories look like so far, and they think this relatively new theory must be wrong --- the physicists are proud of this thing they've contrived that would no longer be necessary.

Nice story I suppose.

But your ideal world of every scientist needing to jump on every new hypothesis as the best thing since sliced bread is the opposite of what is needed to advance science. The skeptics are there to provide the goad to the experimenters to work the proof hard.

If everyone were to say "Hey! Quantum Inertia sounds great!. Therefore the EM engine must be great also!".

The idea of being proud of a construct or concept is more of a political thing than a science thing. Its like hanging on to the concept of Trickle down economics like a drowning man clutches at a straw, while TDE has never been shown to work at all. But those who hold that TDE is true are very happy with the idea.

> Because it disagrees with current theories?

That's usually how it works. Current scientists have a lot of time & money & career goals invested in current theories, so they resist the new theories. In the late 1800s scientists fought long-and hard to reject the theory that space was a vacuum (and light had properties of a particle). They kept insisting that space had an "ether" like liquid that allowed light WAVES to propagate, and labeled the vacuum/particle theory to be nonsense.

DARPA is not what it used to be. This is not necessarily bad science; clearly something is going on with the EM drive stuff and given DARPA's budget (over $3B), this is small potatoes to at least disprove something that, as it stands, is suggestive to be incorrect but not conclusively proven either way.

To be frank, DARPA has poured money into projects that money could be better spent on. The former Director, Regina Dugan (now head of Facebook's secret development group, Building 8), had serious controversy when her father's company was awarded a contract to develop a hand-held bomb sniffing technology that failed every test (it was about 100X worse than a trained dog at finding explosives) but they still bought the technology anyways.

Why is it a shame? Let's suppose, for example, that this is completely bunk and doesn't pan out. It appears that the people who are receiving the funding are using it to actually put their theories to the test. Assuming they're real scientists and not grifters, then after running their tests and finding that their theories do not work, they would devote their time to studying something else. You can't know whether or not some hypothesis is false until it has been tested. If it only takes a little over a million dollars to put this idea to rest, that's quite inexpensive compared to a lot of physics research.

You're acting as though you've got a perfect oracle that has given you the correct answer in advance. The theory might seem strange or unlikely, but the universe is a strange and unlikely place. Physics is rife with discovers that made no sense based on our existing understanding of the universe.

Actually... taxes are extremely burdensome on a huge segment of businesses: Small Businesses.

On the other hand, they are also unfairly applied.

Large corporations pay disproportionately less taxes --- and it isn't because the law says larger corporations pay less: It's because
large corporations are more facile to apply strategic accounting and growth techniques to essentially reduce/eliminate much of their tax liability
--- techniques such as Offshoring HQ to a low tax jurisdiction while still servicing customers and using resources in higher tax jurisdictions,
techniques such as using IP Licensing and other arrangements to artificially transfer earnings to their branch in a country that pays little taxes,
And the wealthy due it too..... having billions in the bank and little on paper.
And the culminating result of all such trickery is that tax liability gets shifted onto smaller and less profitable taxpayers, such as small businesses and
less-wealthy individuals that can't really see that they can afford the extra teams of accountants and other costs necessary to implement tax avoidance schemes.

There's observational evidence for dark matter at large scales. Its density can be estimated by observing gravitational lensing, and there are now maps of such. The Bullet Cluster is a pretty neat example of a mass concentration that is detached from the "bright" matter to such a degree that there basically has to be something there that is very massive but doesn't radiate light.

Re:Isn't this how science works?

[thePsychologist]

It's not labeled pseudoscience because it disagrees with current science. It's called that because it is poorly formulated and does not make precise predictions. If you actually look at the arXiv papers, the derivations are a mess and the figures are blurry. There is very little careful examination of anything in them at all.

It is also easy to derive consequences and new ideas from well-formed theories, even theoretical ones. If you actually write something that makes sense, other scientists will usually jump all over it and write more theoretical papers. This guy's papers have been cited very few times by anyone but himself. That's another sign he's a crank.

That doesn't mean everything in them is nonsense, but for pete's sakes if you're going to present a radically new theory, make sure you pay extreme care to the derivations and details. That is, make it understandable to others in similar fields.

Speaking for the public, it is a huge waste of money to invest in testing papers like this, especially at this level of funding. I have seen hundreds of them, and none of them has ever turned out to be correct.

Actual scientists don't use "hypothesis" and "theory" as interchangable terms.

A theory has been experimentally tested via a procession of repeatable, well-controlled experiments, and has not been falsified in the process. It's a consensus label for a proposed model that seems to hold up to prolonged, intense scrutiny and testing.

A hypothesis, by contrast, is an idea that might or might not have been preliminarily tested before it's presented to its natural constituency, but that has yet to be subjected to serious experimentation (especially by scientists other than whoever proposed it in the first place). Or that has been so tested, but only recently, or only by experiments whose resuts were inconclusive, or which have since been established to have had flaws in design or execution that cast doubt on their reported outcomes.

Dark matter never panned out, and the information out there seems well-reasoned.

Dark matter never panned out?

Sort of like how "evolution never panned out"?

Dark matter has piled up over a dozen different pieces of observational evidence over the years that have been been consistent with each other. Just read the Wikipedia page, it summarizes the different types of evidence that have been uncovered, and has lots of links to the original research.

The McCulloch-written press release (yes, that is what it is) you link to may indeed "seem well-reasoned"*, but only if you aren't familiar with how well confirmed dark matter is. McCulloch apparently believes that the galactic rotation evidence, the first evidence that clearly revealed its existence (there were actually older observations that hinted at it) is really the only evidence there is, so that if he "explains" the rotation differently, dark matter goes away. Actually his theory would have a serious problem since it wouldn't be consistent with all the other observational evidence. He seems utterly unaware of that.

And he is flatly wrong in some of his claims. His assertion that "There is also a philosophical objection: arbitrary models like dark matter are insidious because they can be fudged to be right for the wrong reasons, and dark matter has to be adjusted arbitrarily for each galaxy separately, so it is not predictive." is bizarre. There is nothing "arbitrary: about dark matter, it has gravitational effects and mass distributions that can be measured and mapped.

*Even within the allowance I make above, it is not "well reasoned at all", it is instead a littany of boasts and unsupported claims. Little reasoning is provided.

And then there his promise to explain the "em-drive", an effect that has entirely disappeared when subjected to sufficiently rigorous test procedures.

Re:Isn't this how science works?

[Lanthanide]

Yeah, but that might be because 'dark matter' such as whatever is in the Bullet Cluster makes up say 5% of mass of the universe, as opposed to the current ~85% we estimate at the moment, because we don't have a better theory. In other words, dark matter can still exist and therefore explain specific observed cases, but it might be much rarer than our current theories suggest.

Re:Isn't this how science works?

[Jane Q. Public]

It's only "observational evidence" in the sense that it's a theory that can explain what is observed.

The problem is, there are alternate theories that fit the same observations approximately as well.

Not all of them have panned out; some have been pretty much disproved. But the point is: it's as much "observation evidence" of dark matter as much as it is evidence for those other theories.

Re:Isn't this how science works?

[Jane Q. Public]

But the recent detection of heavy neutrinos (likely "s-tau" or stau) coming from inside the earth has been suggested might lead to either an explanation of "dark matter" or perhaps to a new, alternative hypothesis.

The problem with dark matter is that it would be preferable to have an answer that wasn't such a gross violation of Occam's Razor, which, as you probably recall, says the the correct answer is likely to be the one which makes the least assumptions (or, alternatively, requires the "least multiplication of entities").

Dark matter is an "external entity" brought in to explain the phenomenon, outside of otherwise understood physics.

Occam's Razor is not a physical principle of course. Or a universal law. It's more about falsifiability. It's pretty damned hard to falsify dark matter because at present it's pretty damned hard to devise any experiments which could. Because it's an entity that is external to our known physical framework.

And we prefer falsifiable science to unfalsifiable.

The point being: it's possible that these neutrinos point to a pathway to explain dark matter in terms of already-understood quantum physics, without having to introduce some kind of "ghost" particle.

It's also possible that McCulloch's theory could be an alternate explanation. But either of those might be "preferable", in a philosophical and falsifiability sense, to dark matter, and would likely "upset the applecart" less.

It's not really that simple. Hypothesis and theory are a bit ill defined.

The best definition, closest to what is generally used in practice, is that a theory is some kind of logical and/or mathematical framework that provides some explanatory power. A hypothesis is a specific prediction, that can, at least in principle, be tested by experiment.

A good theory should make predictions (generate hypotheses) that can be tested.

For the most part, DARPA does not even attempt to determine which projects will succeed. The mostly look at what the ask was and how well the proposal meets it.

Until then, you're just pointing out that water falls from the sky yet it only falls down, therefor there must be a river god at the top of the mountain making new water to bring rain and the unending flow.

Look at climate science. They put CO2 and water vapor in a box, shine a light at it, and measure temperature changes and heat retention. You can actually put the CO2 in a bottle. You can compress it into a liquid. You can measure whether it is or isn't there, and how much of it exists. You can correlate how much is there with impacts on temperature retention because you can measure both. CO2 isn't imaginary and predicted to be real because something is different between two measurably-identical things and so something must be there; dark matter is, and somebody is predicting now that there is an alternate property about how things move which would conveniently explain things without some magical sauce we can't seem to measure.

Regarding the defintion of the term I stated:

Which prompted Smidge204 to inquire:

So Quantum Mechanics is a theory, then? Because we've moved a step beyond "intense scrutiny and testing" and we're well into practical real-world applications.

Exactly so - just as is Einstein's General Theory of Relativity (which, at least on the macro scale, has yet to be falsified more than a century after he first published it) is still referred to as a theory by every physicist, astronomer, cosmologist, and scientific journal on the planet. The same is true of Darwin's Theory of Evolution, and there are plenty of other examples to which I could point, as well.

The confusion arises mainly because, in popular usage, the two terms are, in fact, pretty much interchangeable. It's pretty rare, in fact, to see the term hypothesis at all in, say, science reporting for a general audience. And the way it's employed in TV and movies broadens the popular definition to near-meaninglessness.

That millenial dipshit with whom I crossed rhetorical blades has only an undergraduate degree, btw, so it's not like his credential is all that impressive. And his blithering (which he insisted on calling a "theory") was essentially just warmed-over Derrida, wrapped in obfuscatory language, drizzled with poorly-constructed grammar, and floating on a thick, gooey bed of pretention.

Kinda like Derrida's own bullshit, come to think of it - although the Father of Deconstructionism employed better grammar than my quasi-intellectual foil seemed capable of ...

Re:Isn't this how science works?

[painandgreed]

By contrast, dark matter looks at the same problem--centrifugal forces should overcome the gravity of galaxies and hurl their stars out into space, but don't--and suggests that there's a magical, undiscovered form of matter which we can't measure, accounting for 85% of all mass and 25% of all energy in the universe. This creates new gravity (which we can't quite measure, apparently) so the universe doesn't break apart. We can't see it, we can't find it, we can't interact with it, but it's there because things happen that shouldn't happen.

Your knowledge seems a few decades out of date. It's not just galactic rotation, but also observed gravitational lensing around galaxies, observable effects in the cosmic background radiation from the early universe, etc that contribute and are all explained by dark matter. We can measure and find it pretty easily through gravitational lensing. We can interact with it through gravity, but gravity is a very weak force and our current level of detection does not allow for detection below very large scales currently. We have even detected when it has been dislocated from the main body of a galaxy or even removed completely from galactic collisions. Those are going to be the really hard examples of observational data that any other theory such as this one will have to explain, and if it doesn't, then there will have to be several other similarly large discoveries in other fields that will have to be made to go along with it to explain what we are currently observing.

Re:Isn't this how science works?

[mysidia]

It is nevertheless still a force, transmitted by (hypothetical) gravitons.

Um. In General Relativity: Gravity is not a force that acts upon object to affect its motion,
and "gravitons" are not invoked. So long as you are working within this model: gravity is
not a force.

"Gravitons" exist in a different theoretical model that tries to provide a QM explanation for gravity,
but: QM has not been successfully integrated with other physical models that describe
properties such as the motion --- the physics of small particles exists in its own silo,
and has many concepts/terms that are different in implied meaning or don't exist in other
models - for example, in QM you can talk about a "superposition" on the state of certain particles --
but that doesn't work for physical bodies such as a rock or a planet: every planet is in exactly one place --
you wouldn't say at any given time this planet is at both point A and point B simultaneously with a 50% chance of being observed at each....
but with some small particles you could say exactly that.

Re:Isn't this how science works?

[thomst]

ceoyoyo opined:

It's not really that simple. Hypothesis and theory are a bit ill defined.

The best definition, closest to what is generally used in practice, is that a theory is some kind of logical and/or mathematical framework that provides some explanatory power. A hypothesis is a specific prediction, that can, at least in principle, be tested by experiment.

A good theory should make predictions (generate hypotheses) that can be tested.

Eddington's eclipse expedition tested the hypothesis that starlight would be deflected near the eclipsed sun. This hypothesis is a consequence of Einstein's general theory of relativity.

Merriam-Webster's usage note on the distinction argues, in general, for a definition of the two terms that's a bit closer to mine than yours.

That's not to say you're wrong, nor am I claiming that M-W's note entirely disagrees with the distinction you draw. In fact, your contention that the two terms are "ill-defined" is spot-on, and not everyone in the scientific community uses the term "hypothesis" as I defined it. But many do, and the M-W note concludes that, while theories can and do prompt proposals for experiments to test one or another ramification or effect of the theory itself - and that it is perfectly proper to call those proposals "hypotheses" - my characterization of the word "hypothesis" as meaning "a proposed model that may, over time, and with sufficient experimental confirmation, graduate to the status of a theory" is the definition the note's unidentified author considers the best-accepted one.

Again, though, that doesn't make the definition you put forward in any way wrong or misleading. Instead, the M-W note makes it clear that, as you stated, the distinction drawn between the two terms is not a clear, bright line, even among equally-qualified scientists.

OTOH, my clash with that pretentious twit was an earnest of how the jargon of philosophy discards the term "hypothesis" altogether, in favor of watering down the meaning of the word "theory" to the point where it's essentially indistinguishable from "brainfart" ...

Re:Isn't this how science works?

"A theory has been experimentally tested via a procession of repeatable, well-controlled experiments, and has not been falsified in the process. It's a consensus label for a proposed model that seems to hold up to prolonged, intense scrutiny and testing."

This is correct. Though the way you are responding to the quote, it appears you are trying to say QM doesn't meet the level of theory, which is of course absurd since it has proven to be incredibly accurate at predicting the results of many experiments for decades and hasn't been falsified.

All theories were fringe theories at one point

This is not to say we would be dropping loads of money on it, but $1.3 million is hardly that. DARPA is known for spending money on some wild ideas, but it is not known for just tossing money away.

Re: All theories were fringe theories at one point

There is a difference between "fringe" and blatantly contradict well known and measured facts.

Re:All theories were fringe theories at one point

[Solandri]

Yeah. Relativity would've been a fringe theory to anyone who believed in classic Newtonian physics at the turn of the 20th century. Relativity was given consideration because it provided an explanation for some of the observed weirdness which Newtonian physics didn't (Michelson-Morley, orbit of Mercury). If this was just some guy advocating a theory out of the blue, then I'd be suspect of DARPA funding him. But if his theory can explain galactic rotation without using dark matter, then I think it's definitely worth investigating.

The situation in cosmology is similar to pre-Relativity right now - we're seeing something which doesn't make sense using the laws of physics we know of. Instead of making the mistake of ignoring opportunity cost and assuming the most popular theory is correct, think of it this way. We know galaxies can't rotate as we see them rotating using classical celestial mechanics and observed mass. So we've got two competing theories to explain the deviation. Dark Matter, where 85% of the mass in the known universe is stuff we've never seen nor detected and have no idea what it is - basically adding a fudge factor to make our observations fit our understanding of physics. Or this guy's quantized inertia theory. Denying him the funding simply because his theory is fringe is nothing more than blind faith in the dark matter theory being correct.

Even if he turns out to be wrong, $1.3 million is not much in the grand scheme of these things. The DoD and DARPA threw a lot more money at psychic phenomenon during the Cold War simply because the Soviets were also researching it, and they couldn't take the chance that there might actually be something to it which the Soviets might discover first Because we learn from history books which only outline what was investigated, most people wrongly assume there are only two possible outcomes here:

• 1. A theory was correct and was investigated.
• 2. A theory was incorrect, and we wasted money investigating it.

There are actually four possible outcomes here:

• 1. A theory was correct and was investigated.
• 2. A theory was incorrect, but was investigated.
• 3. A theory was correct, but was not investigated.
• 4. A theory was incorrect, and was not investigated.

Like throwing darts, the vast majority of research will fall into the second outcome - investigated and turns out to be wrong. The few shining gems of science (first outcome) are the wheat sifted out of all the chaff via this process. In addition, outcomes two and three and inextricably linked - the less you have of the second, the more you'll get of the third, and vice versa. So decreasing funding for theories which will probably turn out to be incorrect, will increase the number of correct theories we never learn because they were never investigated (throwing the baby out with the bathwater). And trying prevent missing correct theories because we never investigated them, will inevitably lead to more incorrect theories being investigated (casting a wider net will result in catching more trash fish).

There was actually more subtle and powerful argument. The Greeks eventually had a pretty good handle on the size of the Earth. So if the Earth goes around the Sun, that implies that we who think we are standing still are moving about a thousand miles an hour. Wouldn't we notice?

Until inertia is formalized as per Newton, the intuitive answer of "oh, I feel like I am still" has a strong emotional pull.

Worse still, how fast are we moving around the sun? It turns out be a much greater speed. So why don't we notice that?

And how come there is no apparent parallax detected when looking at the stars? Unless the stars were "ridiculously" far away, why don't we notice certain stars seem closer/brighter at different times of the year?

Re:All theories were fringe theories at one point

[Dorianny]

I'm guessing when you picked "relativity" as your example you didn't realize that the "general theory of relativity" is the theory which quarantined inertia contradicts.

However its major weaknesses is that the transition point where Newtonian dynamics breaks down has to be “tuned” to fit observational data without giving a proper explanation of the adjustment. A good mathematician can tweak almost any theory to match observational data

Sure. Let's investigate it. However, don't get any hopes up. Besides galactic rotation, this also needs to explain observed gravitational lensing (and lack of it in certain cases), observed cosmic background radiation, and several other directions that have come to point to dark matter. 70 years ago, this would have been a really intriguing experiment, and it was since this is just a modified MOND theory. However, now it's up against 70 years of testing and experiments which it will have to explain. End result, even if it does exist as the reason, it will still be best shown as a mathematical method that will treat it as a halo of matter that only interacts by gravity with other nearby matter and light.

Re:All theories were fringe theories at one point

[swell]

" 1. A theory was correct and was investigated. "

When is a theory correct?

We have tested relativity for a long time. Can we say now that it is correct? We have major consensus that we are in a period of man-made global warming. Can we say that theory is correct? At what point can we sit back, light a cigar, and agree that a theory is correct?

There may be exceptions, but generally speaking, only God can say whether a theory is correct. The best we can do is say that a theory is 'generally accepted' by those familiar with the details. Until then we must apply due diligence in the search for flaws.

What does inertia have to do with that is exactly the question. Currently, the working theory of dark matter explains the experimental observations for all of these other things also. If a new theory of inertia explains one of them but not the others also, now there is a whole lot of other answers that need to be found for things that should be related.

Car analogy: We have car that turns over but won't start. It will run briefly with starter fluid applied. The gas gauge reads zero. If we open the gas tank, we smell no gas fumes. However, due to the construction of the fuel intake, we cannot put a hose or dipstick down into the tank to directly measure the level of gasoline. Current theory is that the car is out of gas. Somebody comes up with the idea that the construction of the fuel intake also is preventing us from smelling fumes from the gas. Very fine and well, but explanations for why the car won't start and why the gas gauge reads empty still must be found if it is the case there is gas in the tank but we just can't smell it.

So, like if the car does have gas, but we can't smell it which means there is some other problem with the gas feed as well as a broken gas gauge. Likewise, if this theory of inertia explains galactic rotation but not the others, then we have to come up with explanations for them also which will probably mean that not just dark matter turn out to be wrong, but also several other fields of astronomy and physics also.

Knowing the result beforehand tends to devalue the experiment.

If you want results, you base your theories on observation, not your observations on theory.

DARPA understands this, at least as well as any militarist agency can. They don't want confirmation bias, they want results. Only way to get them is by looking.

Are they looking for positive results? They shouldn't be looking for anything, they should be comparing observation with prediction. All results, whether there's a match or not, have major scientific implications. The implications merely differ according to outcome.

That's "hard" sciences, the soft sciences by and large have gone down the critical theory drain and are now dens of SJWity. Some of them even openly claim to be "post-fact", meaning they're entirely and openly unscientific.

The "oh it's pseudoscience" dismissal without serious consideration is cover-your-ass don't-rock-the-boat tenure track conservatism.

It means that the actual science part has left the building long ago, and all that's left are the various priests and acolytes of scientism.

First, I found QI interesting...

[little1973]

...not anymore. The problem with QI is that it is based on Unruh radiation. This Unruh radiation is supposed to replace dark matter and responsible for the peculiar velocities of stars in spiral galaxies.

Now, here's a problem:
A precise extragalactic test of General Relativity
http://science.sciencemag.org/...

According to this study the rotational velocities of the stars are consistent with the bending of light around the galaxy. That means space-time is curved with the right amount which causes the velocities of the stars.

So, Unruh radiation cannot be responsible for these velocities since Unruh radiation is light and light cannot "bend" light. Actually, our current understanding is that nothing can "bend" light this way, only space-time curvature. This means there is something there which causes this "extra" space-time curvature (eg. dark matter).

I do not believe dark matter exists, but it won't be QI which solves these kind of problems.

I am confused. Space-time curvature is related to gravity. Why can't a whole big big bunch of "light" exert a gravitational effect the same way a little bit of the slow usual matter does? Energy is energy and has mass.

Is there something I am missing?

Re:First, I found QI interesting...

[burtosis]

As an undergrad I worked on a darpa project where it paid 1m USD for a custom distributed network radio architecture that involved repurposing a failed thermometer radio chip with barely any modifications outside of some custom firmware on a pic microcontroller. Considering it never even worked right, it was something a decent grad student could have done in about four weeks for 1k. I'm not sure how to board the gravy train myself, but it's definitely possible with the right connections.

You might be too creative for the current discussion - I wonder if they can associate gravity with light or any other EM radiation, or any wave-particle duality. But most light sources are effectively point sources - does your lightbulb exert more gravity when turned on? - and falls off with the exponential of distance...

But when I think about it, I'm still stumped as to why light ONLY/ALWAYS travels the shortest distance, so I'm no use!

Nobody hears me, and I can understand why their minds are closed, so I am not upset about it. It is now your turn. My apologies beforehand.

Gravity is NOT one of the fundamental forces as has been believed forever. What is the effect that we call gravity if it is not a fundamental force?

Gravity is the acceleration felt by an object when time is moving faster on different sides of the object. In other words, gravity is merely the result of a time gradient.

The funny thing about the time gradient is that it falls off (speeds up) with distance from mass in the exact same curve that an objects gains mass as it gets closer to the speed of light.

This fully explains galactic rotation curves without the need to invoke Dark Matter. It also leads to some very interesting thoughts about the nature of spacetime and electromagnetism.

Unruh radiation is light and light cannot "bend" light

So light gets to disobey the laws of physics now? (or QM at least)
I'm assuming you've made an almost (if not) perfect mirror out of modern metamaterials and created an EM blackhole to trap as much light as possible in one space to see what happens?
As far as I know, nobody has bothered trying this because nobody has really thought to try it.
It'd need to be made of expensive heat-resistant materials and liquid cooling to have any hope of working because even with an almost perfect metamirror, there will be an absolutely tiny amount of energy that gets stuck in the material, leading to temperature increase. And, of course, the metamirror itself.
It won't be cheap.
But it is at least testable and insanely cheaper to test than Dark Matter has been thus far!
So that is why it isn't a fruitless effort.

The supposed reactionless drives that have been built are nowhere near the energy densities required to verify anything of significance, and those quickly fail because of overheating issues. (which would make their use in space extremely limited since it is even harder to cool up there due to lack of cooling media)
Even if they are out-ruled as being some unknown effect of being in orbit of Earth or the Sun, they could still be used in space at some point because the engines still work, albeit at tiny thrusts. Maintaining stationary orbits are all about tiny thrusts.

Experiment is the correct approach

[jd]

Some of the scientists are skeptical, they want evidence. This, too, is the correct approach. Cynicism, which also arises, is not. The difference is that a cynic doesn't care about evidence or models, they're convinced of the outcome in advance.

Cynicism is the enemy of science. It's actually the enemy of many things, but in this case it is the enemy of science.

Skepticism is how we distinguish sounding good from being useful. It is essential.

QI sounds excellent, doesn't involve hyper-invisible particles and offers a simple explanation. But none of those mean it is right. As Fred Hoyle loved to point out, the only valid thing in science is prediction. You must predict and test with an eye to falsifying. Nothing else matters.

And it must continue to do so. So all of the indirect attempts to study dark matter via hot filaments of regular matter must produce results QI can explain as well or better. If dark matter produces more testable predictions that turn out correct, it is the more useful even if it is actually wrong.

I am not keen on MOND because, as with dark matter, there are galaxies which don't fit the model. Theories which only apply selectively or at weekends are probably wrong. However, QI has some interesting aspects and should be tested properly rather than cynically dismissed.

"quantized inertia"

[Black Parrot]

Don't know how much you can learn about the QI hypothesis from it's name, but it's clear that mass is quantized, and it is sometimes suspected that space is quantized, so if so, you get the "quantized inertia" for free.

Whether the rest would follow from that is another questions.

The money is for theory and two experiments

[ath1901]

I was very surprised by this since I've read about the Oceanographer McCullogh before and wasn't impressed.

I can't find any official source confirming this except perhaps Univ of Plymouth which is where McCullogh works. Is there an official DARPA announcement out there somewhere?

The only information I can find is from Motherboard (an interview) and forums/McCulloughs twitter. There is some more info here:
https://forum.nasaspaceflight....
search for flux_capacitors post about 1/3 down.

The information seem to be from McCulloughs twitter and the money is for him and a post doc "developing the theory" and two experiments by other people.

The first experiment is this one
http://www.jbis.org.uk/paper.p...
which is supposed to replicate the em drive effect with lasers instead of em radiation.

The second will test a LEM drive (whatever that is).

In short, this is all related to the EM drive which explains why DARPA might think it is worth a small investment. It's not that DARPA suddenly thought QI sounded interesting but rather practical experiments to figure out what is going with the EM drive.

I am still surprised McCullough gets money for doing theory but the experiments sound like reasonable high-risk high-reward investments.

No good gravity theory

[manu0601]

When it comes to gravity, it is odd to call a new theory a pseudo-science, since the main theory has so many shortcomings.

As summary notes, it does not even manage to explain how galaxies can exist: according to main theory their rotation should expel the matter and dislocate them. Dark matter and dark energy, which has never been observed, is required to keep galaxies confined in the standard model

Verification of QI

[AlwinBarni]

I found an article about ways to verify QI: https://www.nextbigfuture.com/... An interesting paragraph is:

4. The opposite case, for objects coming from deep space into the Solar system, or into galaxies, their acceleration is increasing so they should gain inertial mass by MiHsC and slow down anomalously, just like an inverted Pioneer anomaly, and of the same size (it will appear as though there’s unseen mass at the outer edge of the system).

It's interesting because just recently I read about detected anomaly in Oumuamua trajectory, which for now was attributed to not observed out-gassing, i.e. out-gassing, which was not seen, but had to happen - not sure though whether the effect would match the one predicted by QI (article didn't provide details about the anomaly).

It is a hypothesis, not a theory

[techdolphin]

Quantized Inertia is a hypothesis, not a theory. While in general usage, a theory can be a guess or educated guess, in science, a hypothesis is the educated guess. It only becomes a theory after it has been verified repeatedly by experiment, and there is virtually no doubt that the hypothesis is true. Science articles should be careful to use the terms properly.

Moon Shot Concept

[kenwd0elq]

Science fiction author Jerry Pournelle used to advocate that NASA and DARPA should spend 90% of their budgets on routine research following established theories - and spend 10% on "crackpot" theories that might either be utter nonsense or groundbreaking. The "Dean Drive", for example, or the ElectroMagnetic Drive - which NASA _is_ looking at, just because it would be such an enormous leap forward in the unlikely event that it works.

I think "Quantized Inertia" would fall into that same category; likely nonsense, but it's remotely possibly an enormous leap forward. Or perhaps "Quantized Intertia" is how the EM drive (supposedly) works? It's certainly worth trying. One needs to keep an open mind, conduct thorough experiments with detailed descriptions and HONEST results. Pournelle suggested that 19 our of 20 times, the result would be the expected nonsense, but if even one time out of 20 was successful, it would pay for itself a hundredfold.

Little reasoning is provided.

This shows you haven't dug very deeply into his work. And I get it - at a surface glance it does appear to fly in the face of some things that are widely accepted now. But don't forget the luminiferous aether was widely accepted.

I think I can give you the gist of his argument, or at least maybe some food for thought.

The Casimir force has been experimentally verified fairly well at this point. Would you agree with that statement? If so I have another related thought.

The Casimir force arises from virtual particle pairs not being allowed to form in a small space in between two metal plates, making a sort of vacuum. The particle pairs on the outside are more numerous resulting in a net pressure.

Here's the important bit. At what range does this effect stop?

In other words, if the plates are a micron apart we have Casimir forces. Do we have them at a range of an inch? A foot? A light year? And if so what would the consequences be?

That's really all Dr. McCulloch's work is. What if Casimir forces are summed up over a Hubble scale?

"String theory is falsifiable and could easily be tested by experiments.

If you want to blame anyone, blame the Americans for not building the supercollider in the right place and then not building it at all."

Do you have a reference for this assertion? I assume you are referring to the cancelled SSC, which was planned to accelerate protons to 20 TeV, far lower than the bolded value from the citation below. Here is a reference that indicates it might not be as simple as you say.

The strings can become excited to higher modes, which is a prediction specific to string theory and in principle observable. The energy necessary to make these excitations depends on the radius of string theory’s extra dimensions: The smaller the radius the larger the energy necessary to excite the strings. The most natural scenario puts the radius of the extra dimensions at the string scale: on the order of 10^19 GeV, give-or-take. In this case, testing string theory is hopelessly out of reach of the LHC, which reaches ~10^4 GeV at maximum, even with the recent upgrade.

Re: Wait, so there are actual experiments?

[jd]

I'm referring to specific predictions made by string theorists in 1986 at the 300 Years of Gravity symposium, specific predictions regarding supersymmetry, specific predictions regarding leptons and specific predictions regarding supergravity.

Why should I care about string excitation when the falsification of any of the above would falsify string theory?

You're also looking at magnets at the time of the SSC. Those at the LHC are superior. Upgrade your numbers to where the supercollider would be now not then.

Re: Wait, so there are actual experiments?

[Anonymous Coward]

Supersymmetry is also predicted by other theories, so it isn't a unique prediction of String framework (they shouldn't call it String Theory because Theory is reserved for well established systems in science, such as GR, QFT, evolution, etc). Also, given the landscape problem, if supersymmetry wasn't found at the SSC they could just say that it only appears at higher energies, as some scientists are currently saying after the LHC has ruled out the more plausible SUSY theories that solve the naturalness problem already:

The first step is to backpedal from their earlier claims. This has already happened. Originally we were told that if supersymmetric particles are there, we would see them right away.

        “Discovering gluinos and squarks in the expected mass range [] seems straightforward, since the rates are large and the signals are easy to separate from Standard Model backgrounds.” Frank Paige (1998).

        “The Large Hadron Collider will either make a spectacular discovery or rule out supersymmetry entirely.” Michael Dine (2007)

Now they claim no one ever said it would be easy. By 2012, it was “Natural SUSY is difficult to see at LHC” and “"Natural supersymmetry" may be hard to find.”

Step two is arguing that the presently largest collider will just barely fail to see the new particles but that the next larger collider will be up to the task.

Hence the surprise when the supersymmetric partners of the known particles didn’t show up — first at the Large Electron-Positron Collider in the 1990s, then at the Tevatron in the 1990s and early 2000s, and now at the LHC. As the colliders have searched ever-higher energies, the gap has widened between the known particles and their hypothetical superpartners, which must be much heavier in order to have avoided detection. Ultimately, supersymmetry becomes so “broken” that the effects of the particles and their superpartners on the Higgs mass no longer cancel out, and supersymmetry fails as a solution to the naturalness problem. Some experts argue that we’ve passed that point already. Others, allowing for more freedom in how certain factors are arranged, say it is happening right now, with ATLAS and CMS excluding the stop quark — the hypothetical superpartner of the 0.173-TeV top quark — up to a mass of 1 TeV. That’s already a nearly sixfold imbalance between the top and the stop in the Higgs tug-of-war. Even if a stop heavier than 1 TeV exists, it would be pulling too hard on the Higgs to solve the problem it was invented to address.
