i dont think its relative to strength/lumens also his theorey about electronic clocks desync when one is moved away from another is dumb as hell
indeed it seems ridiculous, but i have heard/read many many times that clocks in motion on planes & such do get de-syncronised, and according to this article, https://www.nature.com/articles/news.2010.487 relativity does not need big distances nor speeds.
i can only think of a way of proving if reflected light is slower than emited light.
a variation of the clock experiment try & use of 4 clocks, you start by taking one pair of clocks in one place & sync them, they are right next to each other & they should tick exactly, next you do the same to 2 other clocks 10km away (or whatever distance is needed to notice a change)
clock # 1 will fire a beam , as soon as the beam is fired the clock's timer begins ticking, that beam will be reflected on a amirror lets say 3 kilometers away & come back to the clock itself, making its timer stop.
i am using this simple & inaccurate numbers as an example:
the beam fires & after 6 seconds the clock # 1 stops
that means the light beam traveled 0.5 kilometers per second, in total.
if the convention is correct, then we proceed on syncronizing the clocks, taking into account the supposed delay from the firs data
again clock #1 is in mexico, clock #2 is in US, this time clock #1 will fire a laser at clock#2's sensor when clock #1's timer reaches 3, the sensor starts clock # 2's timer, when clok #2´s timer reaches 3, it fires a laser at clock#1 & stops its timer, & clock#1 will stop when it detects the beam fired from clock #2.
so if everything follows the convention stablished by the mirror experiment,, light will travel from 1 to 2 in 3 seconds, and light will travel from 2 to 1 in 3 seconds, so clock number 1 should end up with a counter of 3 + 3 + 3 + 3 + the nanotime it took for clock 2's mechanism/electronics to fire the laser. so in total clock # 1s timer should be 12 & 1millisecond (the millisecond is the time it took for the second laser to fire)
however if the number turns out to be less than the exact amount predicted, then that means there was a difference of speed, so the next phases of the experiment is to try and reverse the experiment using the other clocks to see if direction affects the results too
