The light clock thought experiment is really quite simple. 1) The light must travel further in one frame than the other. 2) The extra...

The usual light clock does not contain sources of light located on a flat inclined surface. Both mirrors are oriented horizontally. I...

The sensor (at time of reception) subtends a different angle at the emission point in the two frames, as I said. Remember that it is...

The conclusion that I mentioned was this: Your starting point is that the light clock is wrong. It is not. So that is a wrong starting...

Sorry, but as it stands, I see no point in doing this, because you have left out crucial things. Here is what I think you need to do to...

This is easy to address. Photon counting arguments are risky because not all states preserve photon number. A better approach is to...

Yes, that is completely correct. I think his confusion is about this part, which is why I focused on it, but I completely agree that...

Note that in a light clock scenario, this pulse reflects off the second mirror and reverses direction. I don't know that accounting for...

Before we start, let's be very clear. The light clock works. The purpose of this thread is not for you to explain why it doesn't work...

Hi Everyone, this thread is related to @DmitryS previous thread, but after that thread he and I discussed the issue that led to closure...

Excellent. Now, notice that ##v(x)=v_{rot}(x)+v_{trans}(x)##. So this decomposition into rotational and translational components does...

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...

Excellent, except that you will want those as vectors, not just the magnitudes. So for the rotating $$v_l(t)=(-\omega l \sin(\omega...
