Killing fields commute if they are asymptotically coordinate?
.
I don't know if this is true for all KVFs, but we know ##X## is a commutator of two KVFs whose asymptotic behavior is known, which makes...

True, but you have specified that the spacetime is stationary and axisymmetric. You have also implicitly specified that it is...

I
Killing fields commute if they are asymptotically coordinate?
.
The relevant properties in the asymptotic limit are that ##T## has unit norm in that limit and ##\Phi## is orthogonal to ##T## in that...

I
Killing fields commute if they are asymptotically coordinate?
.
I'm not suggesting that it be assumed. Isn't it already known to be true in, for example, the Boyer-Lindquist chart?

Can you find a chart in which ##T = \partial / \partial t## and ##\Phi = \partial / \partial \phi## everywhere? If the two KVFs commute...

EPR in Bohm formulation
.
Ok. But note that that is not the same as what is done to test the Bell inequalities, or other related ones such as CHSH. To do such a...

In other words, once you specify which measurements are being made. Yes, but the probability you calculate is only valid for that...

Most efficient way to randomly choose a word from a file with a list of words
.
This would favor longer words since a random byte is more likely to end up on a line with a longer word than a shorter one. As I...

EPR in Bohm formulation

There is no such thing unless you define what measurements are being made. And the result can be different for different specifications...

Conservation of stress-energy tensor

@dextercioby the correct formatting appears in post #3. That's good enough for readers of the thread.

What does "the total probability" mean? Why is it even meaningful at all?

Are there any accepted relativistic interpretations of quantum mechanics?

Only if you assume that "observer" and "observed" are fundamentally different kinds of things. Which is a circular argument. Similar...

Then you know Alice's result so you are in the second case I described. That's because the angle between Bob's and Alice's measurement...

No, that's not what we know. We know that, if we just look at Bob's measurement and do not look at Alice's at all, then there is a 50%...
