It doesn't slow. c is c, but it does lose energy.
well C is not always actually C as we define it. Light has been observed traveling at different velocitys in the universe a few times now.
does time dilation effect the speed of light ?
The medium that it travel in does. C is the speed of light in a vacuum
Thank you for your help. It makes sense it gains and loses energy![]()
The real question is what is gravity and what is light. They are one in the same. They are waves. (Over siplification added). Along with this you might consider what is the speed of quantum particles and how do they travel (Through Rock)?

This is all a bit above my intelligence level, but this website tries to explain it.
I still wander what keeps light from exiting a black hole. It could be that gravity can become so powerful that it has an effect on time and that has an effect on our perception of light.
Eh what? One is a photon/electromagnetic. The other is gravitational/hypothetical graviton. Gravity is about 10^36 times weaker than electromagnetism. The only possible resemblances I can see are that both are forces, both can attract objects, and Coulomb's law and Newton's law of gravitation look kind of similar.The real question is what is gravity and what is light. They are one in the same
I think that simply has to do with escape velocity. If an object is moving at or beyond the escape velocity of a particular gravity well, then it will be able to escape that gravity well with its own momentum....

So you wonder where photons wander off to in a black hole?
While photons have no mass, and so should not be affected by gravity, the path they travel through is affected by the warping of spacetime in the presence of a large mass. Therefore in the case of a black hole, the mass is so great the photons path bends back into the black hole, there is no escape. It is absorbed into it, where I assume it gets converted into energy in the form of heat.
In other words, the structure of spacetime itself prevents the escape of any photons of light from a black hole. Make sense?
Does light escaping earth slow with the equivalent of earth's escape velocity while they are in earth's gravity well?
You're not making much sense. Can you elaborate?I prefer my idea of gravitational red shift with a black hole : The wavelength of the photon wave is stretched to an extreme because of the stretched out 3d space - time aether. The stretched 3d space -time aether is the result of the accelerated expansion at the center of the black hole. When matter is condensed enough that it's matter acts as a single mass only then this expansion will happen at an accelerated rate. It is interference of the individual fields of the particles when seen as 3d spherical waves. The increase in gravity is also a result of this. Because the wavelength of the photon is stretched out so much, it no longer interacts. It is the same(although reversed effect) as why there is no sharp contrast between a shadow and light(interaction) and why light does not bend around a corner resulting into shadows. It also accounts for missing matter the so called dark matter. The only thing i question about is what happens with the energy of the photon? I never was able to solve that.
It would be extraordinary if they managed to slow it down in a vacuum. What they did is cool, but not exactly revolutionary.You guys bit off more than you can chew.
