Playing “what if?” is a useless game. What if we discovered magnetic monopoles all over the place? What if we saw things spontaneously starting to rotate? It would force us to rethink a lot of physics. But until there’s empirical evidence, it means nothing. Einstein didn’t exactly embrace quantum mechanics. He was wrong, so why does it matter what he called it? If the value of c actually changed, then the length of the meter and duration of the second would also have to change to give us the same answer. i.e. things would have to actually get bigger or smaller. But we also have dimensionless constants (like the fine structure constant) that are actually constant, too. This isn’t the problem you seem to think it is. When you have a testable model of how this can happen, be sure to present it. Until you do, though, this is just bollocks. Science goes with the best theory it has for any particular phenomenon, and that means having a model and evidence to support it. Any notion of what light does or does not experience is fiction; we don’t have any physics that describes what happens from light’s point of view - it doesn’t have a reference frame. And again, when you have a testable model, present it. Anything else is just noise without a signal.

So? The point was they said “we atheists” which, as I was pointing out, implies a totality, not a majority. If they had said a majority, or many, it wouldn’t have been an issue.

It’s happened before (adopting the Gregorian calendar), and lots of people didn’t like losing 10-11 days. That shift was caused by not having the solstices on the right days, so Easter wasn’t on the right day, and the Christians might object to mucking it up all over again

If you added a day, the subsequent solstices and equinoxes would happen a calendar day earlier. (something that should be happening Mar 1 shifts to Feb 29) If you added a day to one month but subtracted it to a later month, there’s no net effect afterwards. We do this with daylight saving. Noon has not moved over the years. You could simply not observe leap years for a while, but why?

It’s more than that. The speed of EM radiation traveling is just one phenomenon limited to c. Yes that’s absurd, but it’s not done, so what’s the problem? We do measurements of c over much shorter distances Again, it’s more than one thing. But it’s not. If you’re going to claim that it is, you need to present evidence. Assertion isn’t enough. In any system of units something must be defined, but the definitions involved were not always based on what we use today. The second was once defined in terms of the length of the year - “the fraction 1/31,556,925.9747 of the tropical year for 1900 January 0 at 12 hours ephemeris time” and the meter was the length of a platinum-iridium bar. Using those definitions it it entirely possible to independently measure the speed of light. But with our knowledge of relativity (and other physics) we’ve moved away from using physical artifacts and toward a more precise realization of the fundamental constants.

Yes. The temperature is just a measure of the kinetic energy of the particles comprising the gas, and that doesn’t change since there’s no work being done. There’s nowhere else for that energy to go.

No temperature change for an ideal gas.

bangstrom has made some dubious claims about entanglement. This thread was split to speculations so they could provide evidence to support those claims, and the rest of us could rebut anything that’s incorrect.

That’s not entanglement, and if you are acknowledging the time delay corresponding to c, it’s not nonlocal

The electron had been discovered 25 years prior to this publication, so no, that claim about electrons being unknown in his time isn’t correct. There’s nothing in these snippets that indicates entanglement is involved.

Saw the video and recalled this thread, just in case anyone wants a very clear and thorough explanation

This doesn’t happen spontaneously; metabolism requires intake of whatever is used to fuel the metabolism. On a per-reaction basis. Then you have the number of particles/entities engaging in the reactions. The fusion rate in the sun is almost 10^38 reactions/sec

A typical cat is not a quantum object. It has a definite state beforehand. If it’s Schrödinger’s cat, in a superposition of alive and dead, and you flatten the box it’s in, did you kill the cat or was it already dead? Can you say for sure that you changed its state?

If it’s the critters, then there’s biology and its subforums (e.g. evolution) If it’s paleo earth there’s earth science, and if it’s some admixture you can always put it in other sciences. Mods and experts can move topics if necessary and it’s not really a problem unless becomes a chronic issue (like posting everything in the Lounge or other clearly inappropriate section)

But we’re talking about entanglement, where the states are unknown, so you can’t tell there is a change in state. You only know the states when you make the measurement. “Change” implies two measurements (initial state, final state)

Thatcher was PM starting in 1979, while Reagan was inaugurated in 1981, so there’s a causality issue here. And other countries had to elect leaders who enacted those policies. Reagan didn’t force that to happen. Reagan is responsible for some awful US policies, but other sovereign nations have agency. If they chose awful policies they are responsible for them.

While I agree Reagan is responsible for certain problems in the US, I’m not sure how he’s responsible for inequality elsewhere in “the west” How can CNN be more silent than Fox news? At least 10 people ran in the GOP primary. How were they not given the opportunity to become a candidate? RFK Jr, Jill Stein, Cornell West and Chase Oliver were all on the ballot (though not all in all states). But if you’re going to claim that the problems of the west have been caused by Trump’s election, you’re going to do a better job of laying out your argument. Especially for problems that existed before 2016.

You can’t tell which electron is which by what state they are in, so you can’t say that anything has swapped. “Swapping” would imply that you knew what state each was in. An electron is a spin 1/2 lepton with a mass of .511 keV and charge -e. To me that’s its identity, but it’s the identity of any electron. If you don’t use physics terminology then there’s a good chance nobody will know what you mean.

Which is a meaningless observation, since they must interact in order to become entangled, and interactions affect the states of particles. It’s not the identity that‘s swapped - e.g. an electron doesn’t become another kind of particle, and electrons are identical particles. The state of the particle is what is teleported. If you think this is a good analogy it suggests you don’t know all that much about quantum teleportation.

I agree, which means this is all premature. But for “who will be the first to go” of people named (not actually taking their post) then the answer is Gaetz, game over, all done.

Gaetz is already gone, and others who have been named might not be in consideration come January 20th. Are we including them?

No. In entanglement, you don’t know the individual states. If you start out knowing, something must happen in the entangling interaction so that you lose track. The atoms would be in a superposition, rather than one in a higher and one in a lower state (and “below the ground state” is nonsense)

You do know that Steve Jobs is dead, right? You keep using the present tense in these descriptions

“Men with ED use computers more often since they aren’t having sex” is another conclusion one might draw. How the hell is “a higher genetic susceptibility to leisure computer usage” determined? They also suggest more activity is the solution, but also say that being sedentary isn’t the problem. A survey, not a double-blind effort, which raises the question of how they determined the genetics involved. Sounds like a load of crap.

FYI the five post limit only applies to the first day. It’s an anti-spam measure Why does it require an energy exchange? Then why bring it up? Interpretations are not theories. They are ways of thinking about theories to help one understand the outcomes, but do not contain any physics that’s not in the actual theory. Anything traveling backward in time will have a partner traveling forward. Energy will be conserved. But the waves in the transactional interpretation are wave functions, which don’t contain energy, so this is moot. There’s no interaction.
