Here is a demonstration:

Not really the answer to the OP's question, but an interesting observation. Assuming that the mass squared $$m^2=p^{\mu}p_{\mu}$$ does...

Always. An extended object should always be interpreted as a collection of separate objects, even if there is no relative motion between...

Yes, but I think the right question is this: Can general relativity (GR) "change" topology? Or more precisely, is GR a theory of the...

He says "associated with". Why not just "is"? Because actually, no, the position he describes is not Everett's relative state...

If he doesn't like the Everett type interpretation, then why (at the bottom of page 7) does he say "The position I am going to advocate...

Maybe he does not explain it very well, but since now I'm in the charitable mood, I tend to interpret it as an implicit assumption of an...

For a change, let me now try to analyze the Coleman's argument by using the charity principle...

I argued that Coleman assumed interpretation B, according to which the observer does not distinguish different straight trajectories. It...

On the contrary, it's crucial to it, for the reasons I and others explained several times.

Because if you can prove it, you have solved the problem of measurement in QM and deserved the Nobel prize. :partytime:

Do you think that there is a specific trajectory?

You already asked me and I already answered. See #108.

And my claim is that it depends on what one means by "seeing a definite trajectory". It is correct in interpretation B (in which...

Yes, my post #106 is also written in that spirit, so we basically agree on that.
