That's a pretty trivial experiment.Concluding that velocity of light is constant is a misconception.According to what experimental evidence?
Of course, we can assume jan19 is speaking of speed of light and not velocity of light, but he didn't actually say that.QuoteSo in Minkowski spacetime (no gravity), the direction that a particular photon is traveling is frame dependent. It might be going North in one frame and the same photon going East relative to another.Velocity of light is not constant. Velocity of light is relative.According to what experimental evidence?
Also, I think once again jan19 is speaking of the coordinate speed of light (as opposed to the speed of light which is constant), which varies with gravitational potential, not with the local gravitational acceleration rate.
So for instance, the coordinate speed of light on Saturn is higher than it is on Earth despite Saturn massing more and the gravitational pull there being 8% higher. Similarly, the coordinate speed of light on Mercury is the lowest of all the 8 planets despite the gravity there being the weakest on the list.
Light can not escape a black hole? Space is emptiness that can be occupied. Space is absolute.
