Something similar happens with waves in classical physics: the phase is determined by our choice of where we choose ##t=0##. I'm not sure how illuminating this correspondence is.

This thread has reached and passed the point of diminishing returns and will remain closed.

Who needs gravity? Check out "The Integral Trees" by Larry Niven.

It is Newsweek doing their best to describe what is going on in to a non-technical audience using non-technical math-free language.

That might be true if you're considering only the intro-level study of general relativity, but there's an enormous amount of active work in the astrophysics community. Searching for "neutron star" on arXiv just now brings up 22,638 papers, many/most in the astrophyics-HE (high energy) section.

You are conflating a bunch of different things here. Much of what you mention above (probability as squared amplitudes, role of decoherence, indifference to single outcome question, interaction with the measuring apparatus) is part of ordinary non-relativistic QM as well - although often...

you can, but you’re using the time dilation formula in the calculation…. and the derivation of that formula includes the assumption that the one-way speed of light is equal to the observed two-way speed. So the logic is unfixably circular.

Of course not. You’re trying to apply non-relativistic quantum mechanics to a problem in which relativistic effects matter.

If we take the math strictly at face value, which means ruthlessly resisting the temptation to indulge even very plausible interpretational claims: ##p## is an observable so ##p/m## is also an observable that we might reasonably call velocity. And if we're considering non-relativistic QM (not...

You have a calculated a quantity that has the dimensions of distance over time, and you can interpret it as a speed (it's an interpretation because it is not observable even in principle and because there's no position that is changing with time) if that interpretation is helpful. But it's a...

You have overlooked the relatively of simultaneity. Say that observer A is located on earth, B on the ship, and both agree that the ship leaves earth at 12:00 noon. One hour later A looks at their clock and sees that it reads 1:00 PM, as we expect. A uses the Lorentz transformation to...

No position means no path along which we can integrate to find the proper time. Instead we use QFT and calculate an amplitude for a decay event at various points in spacetime - "experiences time dilation" is not how I would describe that model. And note that the abstract of the paper does not...

I think you misread what I said.

I am sorry, but Grok has lied to you. The forum rules specifically do not allow posting any theory that has not already been published in an appropriate peer-reviewed journal. What you can do here (take a look at the mission statement in the forum rules) is find what the best current science...

How should the Lorentz factor be applied to motion that is not classical? We don’t. Proper time is the length of a path through spacetime between two events; the electron has no path or position so the notion “the proper time of an electron” is meaningless. Instead we work with the time...
