The speed of light is constant. Gravity can bend it, but it does not change speed.There are however, hypotheses that the speed of light may be relative or fluctuate. João Magueijo is one such proponent of Variable Speed of Light (VSL) theory, which proposes that the speed of light was faster in the early universe.
the speed of light is relative isnt it...for example if you are travelling at the speed of light and you shine a light ahead of you...it still travels away from you at the speed of light...in essence it would be going twice the speed of light even though it would going at the same rate

That's the thign though, it would not be going twice the speed of light.

I don't think so. I'm just confused though. I'll go back to biology. 😉

actually i'm worng...i just looked it up...while the light would take just over half the time to reach a point X from a ship travelling just under the speed of light compared with that of a light shined from a stationary object....it is the time that is relative and not the speed of light
because the time measurement changes...when you do the calculation for each light source...the speed of light ends up the same

Cool. ✅ I thought the answer was more along these lines.
