On moon velocity of light is little faster than that on earth, this small change does not cause antennae failure.
Velocity of light is inversely proportional to gravity, i
Energy = Mass . Length . Length / Time . Time
Velocity = Mass . Length / Time
Gravity = Length / Time . Time
Velocity of object ... V = Mass . Gravity . Time [ Velocity is directly proportional to gravity ]
Velocity of light ... V .V = Mass . Mass . Length . Length / Time . Time = Mass . Energy
Energy = Mass . Length . Gravity
Mass = Energy / Length . GravityVelocity . Velocity = Energy . Energy / Length . GravityVelocity . Velocity / Energy . Energy = 1 / Length . Gravity

Concluding that velocity of light is constant is a misconception.

Velocity of light is not constant. Velocity of light is relative.

That's a pretty trivial experiment.Of course, we can assume jan19 is speaking of speed of light and not velocity of light, but he didn't actually say that.QuoteQuote from: jan19th1980 on 01/02/2022 16:56:38Velocity of light is not constant. Velocity of light is relative.According to what experimental evidence?So 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.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.

This is true since the speed of light is the ground state of the universe.
