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

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

Just to point out that in individual cases, a vector ##\left|\psi\right.\rangle## can be a simultaneous eigenstate of non-commuting...

I have every Larry Niven book ever written. :wink: Alas, there appears to be a paucity of neutron stars with smoke rings in our Solar...

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...

You are conflating a bunch of different things here. Much of what you mention above (probability as squared amplitudes, role of...

you can, but you’re using the time dilation formula in the calculation…. and the derivation of that formula includes the assumption that...

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...

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...

Seen in terms of geometry, it is closely analogous to two cars driving at equal speeds ##v## down straight roads that make an angle...

I think it helps to suspend your disbelief for as long as it takes you to learn how it works. Putting your mental energy into arguments...

You have overlooked the relatively of simultaneity. Say that observer A is located on earth, B on the ship, and both agree that the...
