Thank you all. I will think about it further.

Thank you so much. Then I should appreciate it if you let me know whether all these theories deal with collapse of entangled wave...

If no theories in the direction I have mentioned have been explored in response to the OP’s question, please excuse my oversight.

Collapse of (entangled) wave functions comes from measurement. If not only the concepts of the collapse but also measurement in general...

It seems that this problem cannot be properly understood without mastering relativity. Until then, however, how about the following...

Einsteins seems just applied the general rule of variation for product H=ABC, i.e., $$\delta H = \delta A\ B\ C+A\ \delta B\ C+A\ B\...

In SR, proper time of the object in motion with velocity v(t) is given by $$\tau = \int_0^T \sqrt{1-\frac{v(t)^2}{c^2}}dt$$ where once...

I concur with Pallen's observations. MTW goes into the explicit geometric details of how to construct a proper frame of reference. And...

You use alphabet k to mean two different quantities i.e., spring constant and wave number, which cause the confusion.

Indeed. Next I survey my environment to construct my PFR which might not be defined unikely. That will be a tough work to do.

It seems odd to me too because I think Minkowski coordinate belongs to SR or IFR where we find no problems as for Proper FR.

A proper frame of reference (FR) that is inertial (IFR) does not depend on the observer’s location or size; the observer may be regarded...

Note that the English meaning of "proper" has drifted over time to mean "correct". In this context, though, it's being used in an older...

Your thought about two IFRs seems OK. What’s the problem?

Good! For simplicity and convenience, let’s temporarily choose ##t=0##. At ##t=0## we can use the total ##s## to see that ##y=0##. So...
