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.

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...
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. There is a key difference. If DARPA thinks there is a worth while shot that this research can lead to something value then good on them for taking a risk.
Isn't everything else quantised?
I couldn't begin to comment on whether it is science or pseudoscience with any authority. However, I can only hope that if it is pseudoscience that they might discover something useful by accident whilst studying it.
I'm sure the ideas of computers and self driving cars were considered pseudoscience or science fiction once upon a time.

DARPA is well known for its high-risk, high-reward approach to innovation. I'm sure the program manager involved knows full well that QI probably doesn't exist, but he or she has enough esteem for the investigators it was determined a good investment, just in case it turns out to be real.
They could also be offering some life support to a research group they want to keep together, but doesn't have a clear project. This is done all the time.
Because who doesn't like a pseudoscience theory that can quantify the compression ratio of angels dancing on the head of a tulip as it accelerates towards light speed?

Self driving cars work today. But they aren't necessarily less likely to drive off a pier than your average senior driver.

...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.

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.

Then they tested it again and found it didn't.

Um, actually we developed EM drives back in the 1950s. I know they don't teach real science history in backwards areas, but they even had entire SF series published about it in Germany and the UK, not just in the USA.

I think you're overlooking the fact that every theory put forth to falsify all the AGW studies done to date is just a variation on the same crackpot theories that have already been debunked repeatedly.
I'll bet you're upset that nobody is pouring money into trying to find a link between vaccines and autism, too.
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.
After which, blame a few string theorists for ignoring supergravity and abusing its proponents.
But nothing stops you from testing some predictions of string theory today and building the supercollider in an appropriate location so that you can test the remainder down the road.
The main impediment to testing string theory is the crowd believing without evidence that it cannot be done. Scientists worth a damn should stop listening to them. Science isn't a democracy.

You are using old data. Here: https://www.sciencealert.com/i...
You can read thrust in any direction you want, perhaps in two opposite directions at the same time. And the amount of energy it takes to get that omnidirectional "thrust" is pretty impressive. Personally, I think it is heating effects, and perhaps the magnetic field of the earth interfering. And that's as good a guess as QI. The EM drive will now live on as youtube videos for the perpetual motion crowd, and the people who believe that you can heat your entire house with a tea candle and a clay pot.
The shepherds did so well protecting the flock that the sheep no longer believed that wolves existed.
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.
Sheesh, evil *and* a jerk. -- Jade
As I stated, they did SF series back in the 1950s where they had "advanced EM drives" with no propellant, and they were set in 2040 and 2050. Which makes the timeline correct.

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.

You know, neologisms are OK, even useful at times. Agendas do exist.
But science ultimately is undeniable fact.
In your example, climate change either exists or not. If the data show it to exist, no amount of pro or con- political activism will make it stronger or disappear.
People wanted the Earth as the center of the universe, or flat etc. But the facts said otherwise. If some people engage into political thinking against facts, that means they are making themselves the target of ridicule. It's not skepticism, which is doubting unproven things -- this is doubting already tested and re-tested things, with results reproduced more than once... this is doubting not the theory, that's doubting the results of a documented, independently reproduced and reproducible result.
It is merely being stubborn and deserves the respect which we reserve for fools.
BTW, there's a lot of folks here with weak grasp of logic, as of late, unfortunately.

It's ridiculous that climate change has become political.
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
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).
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.
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.
It's possible that there are unseen - or at least, so-far-unnoticed - effects at work that might be the result of being so deep in the Earth's, or the Sun's, gravity well. Can we be CERTAIN that things might not work just a little differently at a distance of, say, 1000AU? I think we need to keep at least an open mind about the POSSIBILITY that the warped space we're living in so near the Sun might have at least a slight effect.
Climate change affects economics, which affects resources. Politics is how humans allocate resources.
His ignorance covered the whole earth like a blanket, and there was hardly a hole in it anywhere. - Mark Twain
I follow a fairly heated subforum of nasaspaceflight and a bunch of boffins attempting to prove EMDrive (and Quantized Inertia as an explanation). Some of their garage experiments are jaw-dropping in quality (Such as Monomorphic's) . Unfortunately, recent results are mostly negative, or close to "noise level". When you're looking for sub-newton force with high wattage, it's easy to mistake heat / magnetism, flexing of cables as an unknown "force".
In this case, it has already been proven wrong, and mostly survives due to the proponent being good at sounding convincing to people suspicious of domain experts.
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?

rediculous.
Ohhh, cruel! And as a geologist, I've been using barbed spikes and pain-enhancing medications on creationists for decades. With malice aforethought.
I'm perfectly happy to admit that I know nothing about the subject. I've never heard of "quantized inertia" before now. It doesn't look good when all that Wikipedia can come up with on the subject is a link to (this?) Motherboard article (on principle, I don't follow links to Motherboard, since they're invariably unviewable without enabling 438 (or more) advert-servers in No-Script. And then the content is crap when I get there), and a You-Tube video (not worth the bandwidth - see the "if a picture paints a thousand words - it should be smaller than about 30kb" argument).
Sigh. What is on Arxiv? Search for "Quantized inertia" (including quotes) : nothing. Without the quotes : 35 results ... not one of which uses the actual phrase (about as expected), and none look particularly likely. What about the guy's name? 15 results, all single-author papers (not good), but he's been getting published ("Journal ref: McCulloch, M.E. Astrophys Space Sci (2017) 362: 149" ; "Journal ref: Astrophys Space Sci (2017) 362: 57" ; "Accepted for publication in EPL, 13/10/2016" ; "Journal ref: EPL, 111, 60005, 2015" ; "Accepted by EPL (Europhysics Letters) on the 11th February, 2013" ; "Accepted for publication in Astrophysics and Space Science on 27/7/2012" ; "To appear in the SPESIF-2011 conference proceedings, in Physics Procedia" ; "Accepted by EPL on the 16th June, 2011" ; "Accepted by EPL (Europhysics Letters) on the 19th April, 2010." ; "Journal ref: Europhys.Lett.89:19001,2010" ; "Journal ref: MNRAS-letters, 389(1), L57-60, 2008." ; "Journal ref: J.Br.Interplanet.Soc. 61: 373-378, 2008" ; "Journal ref: Mon.Not.Roy.Astron.Soc.376:338-342,2007"
Now, they're perfectly respectable journals (well, most of them. Conference proceedings can be a bit loose.), and they're still getting published every couple of years. Which is not the sound of someone having the doors of the ivory tower slammed in his face. However, there's not a cascade of follow-up there.
Sigh. Got some reading to do, I guess.
Birds are not dinosaur descendants;birds are dinosaurs, for all useful meanings of "birds", "are" and "dinosaurs"
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.
