Re:Not going to happen
Can't bribe or influence an AI the way you can humans; so it's a no-go for replacing any existing government.
Yes, you can.
Google "algorithm bias site:slashdot.org".
There are literally a dozen articles here on Slashdot about bias on social-sensitive algorithims. If they can be biased (and they can), their developers can be lobbied or even bribed.Here, I'll give you not one, but five well-documented examples of AI showing prejudice in their algorithms.

Re:It's only ok to ignore federal law for the left
My google fu is a bit weak right now, but apparently, I was wrong about which group stated it. It was the French Academy of Sciences, not the Royal Astronomical Society. Same idea. https://www.newscientist.com/a... [newscientist.com]
So let me get this straight: You're citing the fact that hundreds of years ago (1794), when man didn't know where meteorites because there was no decent evidence for it is exactly why you should dismiss climate change even though there is evidence for it.
Many scientists agree that Dark Matter exists. Dark Matter is merely the result of torturing a misunderstanding beyond reason. It does not actually exist in any way, shape, or form.
Incorrect. Many scientists agree that something exists which we can't fully explain. For now they are calling it Dark Matter. For now they do not have a complete knowledge on its properties in the same way that scientists didn't know all the properties of all the sub-atomic particles that exist; that doesn't mean that sub-atomic particles never existed.
There are very few things that I believe, but I take it as a matter of faith that General Relativity is as close to real Truth as humans have found. Dark Matter is not predicted by General Relativity.
No and there are many things that General Relativity cannot explain. What happens inside a black hole for example. General Relativity is also completely inadequate when it comes to particle physics. Do you dismiss both because General Relativity cannot explain them.
Now, what if gravity doesn't bend spacetime, rather gravity is a consequence of the shape of spacetime?
No, mass bends space-time. Gravity is the force we describe that process.
All the same equations describe the situation, but now, gravity is no longer a fundamental force. This can be described quite nicely in a primitive two dimensional manner: Any change in the rate of time flow will result in an acceleration towards the lower change in rate.
In what way does the many, many tensor equations of General Relativity not have gravity as a fundamental force?
It is actually much more subtle than that, but General Relativity continues working just fine. Gravity is just an illusion... but I would not recommend stepping off of a cliff. Your body will still be accelerated as would be expected if gravity were not an illusion.
Again, General Relativity does not explain what happens inside a black hole. Science has long known that.
Dark Matter and Gravity are illusions based on our limited understanding of the actual shape and nature of spacetime.
Again, how does that contradict my point? Dark Matter information is acknowledged to be something we don't know. Climate change is the opposite in that there is lots of evidence from many scientists affirming that it is 1) happening and 2) caused by man.

Re:It's only ok to ignore federal law for the left
The obvious one about the Royal Astronomical Society coming to the conclusion that ROCKS DO NOT FALL FROM THE SKY and therefore, anyone who reports finding a meteorite is lying.

... And scientists are not fully sure of what Dark Matter is, but they are unequivocally stating that they donâ(TM)t know.Many scientists agree that Dark Matter exists. Dark Matter is merely the result of torturing a misunderstanding beyond reason. It does not actually exist in any way, shape, or form.
There are competing ideas like quantum gravity but no one has been able to bring forth a verifiable model yet. That doesnâ(TM)t mean General Relativity is wrong.

Short breakdown:
Do a search with the term "gravity bends spacetime". See the results?
Now, what if gravity doesn't bend spacetime, rather gravity is a consequence of the shape of spacetime?
All the same equations describe the situation, but now, gravity is no longer a fundamental force. This can be described quite nicely in a primitive two dimensional manner: Any change in the rate of time flow will result in an acceleration towards the lower change in rate. (time flows faster for an object the further it is from another mass)

Re:Could we add resolution?
Boy did you not get the memo on how this thing actually works.
LIGO searches for an extremely precise signal known as a "ring down" which is entirely unlike any kind of dump truck doing anything dump trucks do.
The problem is somewhat different: a dump truck plus exactly the right random noise might produce a nun-bun artifact in the shape of a ring down.
So it certainly helps to corroborate detections by having multiple detectors.
Grave doubts over LIGO's discovery of gravitational waves — 31 October 2018
I'm not going to read that article again just now, but as I recall it, the detection algorithm is not detecting objects at the two main LIGO installations independently, so that the detections corroborate each other, but combining both signals into what amounts to a single instrument (basically into a single sigma budget, rather than separate sigma budgets).
Secondly, the search is template-driven, scanning for exactly the kinds of ring-downs they expect (hope) to find.
Between these two things, it's certainly possible into deceiving yourself into thinking you've detected something you haven't detected.
(I haven't followed up on this data analysis challenge recently.)
Finally, the cosmic directionality of the two LIGO machines is terrible. I forget the exact number, but between the two machines, you get something like a giant banana whose length is 20% of the sky.
The Direction of LIGO's Gravitational Waves — 6 March 2016
That provides an introduction, but does not quantify the banana in square degrees that I can see on a quick revisit.
Ideally we would have four machines, and the machines would be partitioned for independent detection. Once the detection is confirmed to the same sigma twice, then all four machines can be combined into a single directional assessment, and then we can get hot onto neutron-star mergers in visible light.

Re:Btw I didn't create it, don't like it
At the risk of escalating this "debate":
Could wind turbines withstand Category 5 hurricanes"
This is one of many articles about wind turbines handling high winds. They actually have a "hurricane mode" into which they can be placed.
Article in NewScientist" on failure of wind turbine in the North Sea. And I quote:.
Much of the evidence was burned, and Infinis and Vestas disagree on which was the key initial cause of the destructive fire: Infinis believes it was the loss of yaw control, while Vestas thinks brake drag more the root cause. While Vestas has produced its own report, an expert was not available to discuss its findings with New Scientist. Vestas has since fixed the brake problem. In future, the feathered rotor will not have the brake applied in high winds; it will be free to turn if it needs to. “Vestas no longer do this and have modified all turbines at Ardrossan to prevent application of the parking brake, which is now only applied during maintenance,” says Infinis spokesman Andrew Dowler."
Guess what? The article also says: When wind speeds reach 88 km/h turbine blades of wind turbines are usually twisted, or “feathered” ...
I stand by my assertion. I will agree that airframes are susceptible to failure at airspeeds that are only modestly higher than normal operating airspeeds, however propellers (l.e. turbine blades) are much more robust - again, like propellers on aircraft.
For grins, I tried calculating tangential velocity of propeller tips on a Cessna 172, given a prop diameter of 76" and an RPM of 2800. My math may not be correct, but I've checked it in Excel and I think it works out to 622 MPH. By your reasoning, you wouldn't even make it off the runway before the propeller self-destructed.
Airframes and propellers have totally different strength characteristics, no? -

Re:poor sods
You must have head of the Roman Optimum and the Medieval Warm Period - and the many other examples of this. Even the Little Ice Age.
1. The Medieval Warm Period was localized to the north Atlantic region, with the pacific region getting colder. Current warming is increasing average temperatures across the globe.
2. The cause of the Medieval Warm Period (as per the link) is believed to have been solved.
3. Atmospheric CO2 has increased from ~300 to ~400 PPM since the 60s, in line with increased fossil fuel emissions.
4. The cause of the current warming is believed (by 90+% of the scientists investigating it) to have been solved. Spoiler alert it's the increasing atmospheric CO2.

Re:DO NOT FEED THE LYINWUSS TROLLTangier Island, MD
Micronesia - Eight Pacific islands lost
Islands aren't the only problem. The a huge bulk of human society lives on the coasts. London, Miami, New York, etc. Miami is experiencing far more flooding just from tides than it did just 30 years ago.
London built the Thames Barrier to prevent storm surge flooding. over 50 percent of it's usage has been regular tidal floodingThe Thames Barrier has been closed 182 times since it became operational in 1982 (correct as of February 2018). Of these closures, 95 were to protect against tidal flooding
Sometimes they even close the barrier now at low tide to provide a place for excess rain to go because the rain plus higher tides would be flooding.
Sea level is rising and now rising faster than it has in 100s or 1000s of years.. That simply isn't in dispute.
Larger islands don't discount rising seas until they are overtopped. An island that's 1 foot above sea level can get larger with 6 inches of rise without shrinking - that doesn't mean there isn't a significant problem going forward. -

Re:Top Myths about Nuclear Energy
That's not "quite a few", although thanks for reminding me of the Magnox design, making a total of 3. It's inherent in the CANDU design, where you push fuel through horizontal tubes in the original manner used by the Manhattan Project. Push them through so a fuel assembly stays there only a few months, and there won't be too much of the thermally hot or fissions too easily plutonium isotopes.
But those reactors are not the ones the lies were made about, I'm thinking in particular the hue and cry about that Japanese fuel in the early 1990s, here's the first link I found, by the New "Scientist" at that. Outright total lying, unless you define a "crude bomb" as one that requires 1kW of constant heat removal, quite a trick and makes the whole thing huge (refrigeration equipment plus generator(s) to power it), and a yield less than a kT.

Re:i mean, is this trustworthy?
the closest thing to reportage here is links to a blog and also a graph of some sort i honestly don't have time to bother figuring out.
The graph is showing that every available temperature data set, whether it be it from USA or UK, land or satellite, and even those by skeptics - all show the same thing. Temperature is warming by about 0.2C/decade. The later period is warmer than the former. The climate modeler had greater insights into the mechanisms that affect global mean temperature than the solar physicists. The winner is clear.

Two gyros might work
That leaves Hubble with only two fully functional gyros. At any given time, Hubble needs three of its gyroscopes to work for optimal efficiency.
I found this from thirteen years ago:
In the meantime, engineers have continued planning for the two-gyro mode
... Tests of the mode, in which onboard computers only used data from two gyros, showed the resulting images were nearly identical to those taken with three gyros. One of scientists' main concerns about switching to a two-gyro system had been that âoejitterâ in the telescope would produce blurry images. -

Re:Carbon footprint of this?
Here are some references. You can make up your own mind I guess.
"When an ice cube melts in a glass, the overall water level does not change from when the ice is frozen to when it joins the liquid. Doesnâ(TM)t that mean that melting icebergs shouldnâ(TM)t contribute to sea-level rise? Not quite.
Although most of the contributions to sea-level rise come from water and ice moving from land into the ocean, it turns out that the melting of floating ice causes a small amount of sea-level rise, too.
Globally, it doesnâ(TM)t sound like much â" just 0.049 millimetres per year â" but if all the sea ice currently bobbing on the oceans were to melt, it could raise sea level by 4 to 6 centimetres.
Fresh water, of which icebergs are made, is less dense than salty sea water. So while the amount of sea water displaced by the iceberg is equal to its weight, the melted fresh water will take up a slightly larger volume than the displaced salt water. This results in a small increase in the water level."
https://www.newscientist.com/a...
https://physics.stackexchange....
"When you learned about Archimedes back in elementary school, your teacher probably told you that a floating object displaces an amount of water equal to its own weight. Although an ice cube pokes up out of the water, when it melts, the level of the water should stay the same. Extrapolate this concept to an iceberg floating in the oceanâ"a bigger version of the ice cube in your water glassâ"and you would think that melting icebergs shouldn't contribute to sea level rise. Well, you'd be wrong, say geoscientists at the University of Leeds.
In their study, published this week in Geophysical Research Letters, the researchers used satellite observations and a computer model to assess the impacts of melting icebergs. The total amount of floating ice that is turned into ocean water each year is equivalent to 1.5 million Titanic-sized icebergs. Due to differences in the temperature and density of the ice and water (the seawater is warmer and saltier than the icebergs that float in it), when the icebergs melt, the resulting ocean water is 2.6 percent greater in volume than the volume of water that the iceberg had displaced."
https://www.smithsonianmag.com...
"In a paper titled "The Melting of Floating Ice will Raise the Ocean Level" submitted to Geophysical Journal International, Noerdlinger demonstrates that melt water from sea ice and floating ice shelves could add 2.6% more water to the ocean than the water displaced by the ice, or the equivalent of approximately 4 centimeters (1.57 inches) of sea-level rise.
The common misconception that floating ice wonâ(TM)t increase sea level when it melts occurs because the difference in density between fresh water and salt water is not taken into consideration."

There are plenty more, but if that doesn't convince you then I imagine nothing will.

Re: Is this a good idea ?
You think that an iceberg that is floating in the water has not raised the level of the ocean (ever so slightly), but it will when it melts?
Slightly, yes, due to the fresh water melting into the salt water.
"Fresh water, of which icebergs are made, is less dense than salty sea water. So while the amount of sea water displaced by the iceberg is equal to its weight, the melted fresh water will take up a slightly larger volume than the displaced salt water.

Re:We care about climate change

You make it sound like they just built the plants in the wrong place.
Nuclear plants have some pretty difficult requirements for location. You need somewhere that is geologically stable, where there is sufficient space and isolation to build the plant, waste storage and security apparatus. It needs a supply of water for cooling. It needs to be sheltered from severe weather and natural disasters as far as possible. And it has to have good infrastructure to keep it supplied, connect it to the grid and allow staff and emergency services to get in and out.

Re: Ouargla, Algeria
Actually, "normal climate variability" or "a heat wave" explains it nicely.
That's very unspecific, and goes against climate scientists' overwhelming consensus, specifically that recent calculations concludes that the Earth is warming orders of magnitude faster than from natural forces. Neither "normal climate variability" nor "heat waves" seems to account for past data, nor is able to predict future trends better than AGW.
High daytime temps are NOT part of the catastrophic AGW prediction set, you know. The theory is that NIGHTTIME temps will increase, not daytime, so the overall average goes up.
And when they talk about "consistently higher" temps, they're literally talking about fractions of a degree in most cases.
I couldn't find a source that only night temperatures will increase -- what's yours? The closest I could find was this article explaining why night-time temperatures are warming faster than day-time temperatures. They're both still warming though.
By the way - there have been a few surveys of weather stations, and the vast majority of them have problems, mostly caused by either encroaching cities (the Urban Heat Island effect) or bad instrument siting. Very, very few stations have consistent records, with relatively untouched siting. The ones that do? Well, they don't show the AGW trend that the others do... and the response by AGW scientists is to adjust the ones that aren't showing the increase (AKA "throwing out the good data so the bad data looks better").
Try this site, for a bit of data that will shock you...
http://www.surfacestations.org/
You do not take into account how that data is used and verified. A quick search presents convincing skeptical arguments that these measurements are still reliable as a whole, as they show the same corroborating trends whether they're urban or rural, or lumped into random groups (which would emphasize any inaccuracies from placement of stations):

If it had been any other kind of plant except maybe liquid sodium solar thermal, it would not have been necessary.

Re:No grav lensing
Re: " If the Electric Universe model wants to be taken as real science then it needs to have the explanatory and predictive power necessary to account for all of these evidences at least as well as dark matter."
The answer to the riddle of dark matter is as follows:
(1) At the interstellar scale, gravity is a localized force. This should be common sense, for if the Earth was just an inch from the Sun, the next nearest star would generally be around 4 miles away (this analogy goes by the name of the "Burnham Model"). Simple algebra argues against stars gravitationally interacting with one another at the interstellar scale.
(2) And if you were to actually ask a theorist for proof that Relativity applies at the largest scales, the more honest ones would admit that they lack such proof:
Bankrupting Physics: How Today's Top Scientists Are Gambling Away Their Credibility, by Alexander Unzicker and Sheilla Jones (2013), p10:
"Combing through the library, I found a well-known textbook on galactic dynamics where the authors state:
'It is worth remembering that all of the discussion so far has been based on the premise that Newtonian gravity and general relativity are correct on large scales. In fact, there is little or no direct evidence that conventional theories of gravity are correct on scales much larger than a light year or so. Newtonian gravity works extremely well on scales of 10^12 meters, the solar system (...) It is principally the elegance of general relativity and its success in solar system tests that lead us to the bold extrapolation to scales 10^19 - 10^24 meters
... [3]'Wow! Fancy that. Two leading experts claim that the law of gravity has been well tested in our solar system only -- a tiny fraction of the universe that corresponds to a single snowflake in all of Greenland. Scientists seem drawn to the 'elegance' of the theory, which is not really a scientific criterion. I often confront physicists and astronomers with this quote. Usually they shrug and reply airily, 'That is indeed true, but why shouldn't the law of gravity be valid? So far, there is nothing better to replace it.'"

(3) Wal Thornhill has provided a conceptually simple explanation for gravity which may or may not be correct (I suspect he is close). What is important about his conjecture is that it shows us an example for why gravity might be a localized force. His explanation goes like this:
- Every particle within each atom is made of orbiting ~0 mass charges.
- Every subatomic particle is distorted by the presence of others to form a tiny electric dipole.
Like magnets that are free to rotate, all the electric dipoles in protons, neutrons and electrons line up to produce gravity.
Neutral atoms distorted by gravity induce an electric field inside of a body.
The idea is useful, even if incorrect, because it gives us a simple framework to think and pivot from. For example, it's easy enough to see that gravity should be a localized force with such a mechanism. And we've seen this sort of thing elsewhere -- namely, the Van der Waals.
(4) So, what is happening at the largest scales? We know enough at this point to have a good clue about it. Consider, for example, this clue whose importance has been completely missed by the mainstream:
Many disc galaxies, including our own Milky Way, have a central bulge that resembles either a box or an unshelled peanut. This bulge may form when the circular orbits of

Re:The obvious problem with this
Let me give you another example of a vindication which everybody missed for electricity in space doing things of importance:
In July of 2016, it was admitted that many galaxies exhibit two separate bulges:
Many disc galaxies, including our own Milky Way, have a central bulge that resembles either a box or an unshelled peanut. This bulge may form when the circular orbits of stars become elongated, creating a “bar” of stars that runs through the centre and tilts out of the disc’s plane. The combined effect makes the once-flat galaxy look like it has buckled under enormous pressure.
People who do not track the electricity in space debate would not see this as a vindication for those claims, but it certainly is.
Anthony Peratt simulated proper galactic rotation curves in the early 80's on government supercomputers without the need for any dark matter. . Look carefully at the simulation results, and you will see your two separate bulges.

Re:An epic failure in science journalism
Re: "To answer the is it even worth considering question, though- of course it is. And it has been, at great lengths. And plasma physics play a huge role in even standard cosmology. They just don't play a huge role in large-scale cosmology."
Let me give you a very simple example which I hope you will recognize as an earnest attempt to demonstrate how difficult it is to judge vindications when we are not actively tracking scientific controversies.
Today, for the first time, I noticed that a couple of galaxy artists were suddenly drawing the Milky Way's galactic bulge as a pair, as if a memo went out (which I missed). I had never before noticed this, but having learned about Anthony Peratt's galactic simulation as a pair of rotating Birkeland currents, I immediately tuned into this pattern.
To somebody who has not paid any attention to Peratt's simulation, the explanation offered in a July 2016 article would seem good enough to assume the issue is basically settled:
Many disc galaxies, including our own Milky Way, have a central bulge that resembles either a box or an unshelled peanut. This bulge may form when the circular orbits of stars become elongated, creating a “bar” of stars that runs through the centre and tilts out of the disc’s plane. The combined effect makes the once-flat galaxy look like it has buckled under enormous pressure.
But, hold on just a second. This is a completely ad hoc explanation. Although I have no doubt that somebody somewhere can generate a tweak to the original galactic models -- perhaps involving dark matter -- which can explain with actual numbers why this may occur in the conventional model, the fact of the matter is that this is a completely expected feature when you are modeling a galaxy as an interaction of two Birkeland currents. -- and the choice to refuse to systematically track the Electric Universe controversy has left everybody failing to recognize that this actually vindicates the against-the-mainstream claim.
You think that's just a coincidence? Okay, let's go back a few days to the release of these new pictures from the Juno spacecraft of one of Jupiter's poles in infrared. The article states:
Jupiter’s poles are a stark contrast to the more familiar orange and white belts and zones encircling the planet at lower latitudes. Its north pole is dominated by a central cyclone surrounded by eight circumpolar cyclones with diameters ranging from 2,500 to 2,900 miles (4,000 to 4,600 kilometers) across. Jupiter’s south pole also contains a central cyclone, but it is surrounded by five cyclones with diameters ranging from 3,500 to 4,300 miles (5,600 to 7,000 kilometers) in diameter. Almost all the polar cyclones, at both poles, are so densely packed that their spiral arms come in contact with adjacent cyclones. However, as tightly spaced as the cyclones are, they have remained distinct, with individual morphologies over the seven months of observations detailed in the paper.
“The question is, why do they not merge?” said Adriani. “We know with Cassini data that Saturn has a single cyclonic vortex at each pole. We are beginning to realize that not all gas giants are created equal.”
Once again, I sprung into action because I have tracked Peratt's work sufficient to understand the inherent geometry of electricity over plasma. In his efforts to explain petroglyphs as z-pinch instab

Medical answer
I can't give you an answer for general tech, but medical tech would be greatly advanced by the ability to put people into suspended animation.
Basically, if the person's body isn't *operating* - needing to breathe, needing to circulate, and so on - then repairs could be done much more effectively and cheaply,
I read where gunshot victims would be suspended temporarily as an experimental method a couple of years back.
Whatever happened to that?
Perhaps a combination of sudden hypoothermia coupled with sulphur dioxide treatment or something.
