B What reference frame is used for the velocity v in the Lorentz transformation?

I've been teaching physics since 2008, and I've spent 5 hard years becoming a physicist. We all here thought about these questions seriously multiple times. You have not and you're wasting our time. You are not here to learn. This thread is going nowhere.

This is the problem I encountered when studying physics. Then I presented the problem for discussion!

Then I presented the problem for discussion!

And people pointed MULTIPLE TIMES how to resolve your problem. You did nothing with that. In the end, experiments falsify your point of view. And that's what matters.

After a very brief discussion among the mentors, we will leave this thread closed.

As @weirdoguy mentioned, we have shown how the math and theory solve the problems raised by the OP, and we have referred to experimental evidence showing that the math and theory are correct. At this point the only productive thing is for the OP to review the provided math and experiment. If they have specific new questions after doing so, then they may open a new thread for help.
