Is light affected by gravity?
What should something have to be affected by gravity?
Drakkith said:No, but it has energy.
Yes! Gravity according to General Relativity, which is our leading theory of gravity, is the result of curved spacetime. Anything traveling through spacetime will be affected, including EM radiation that is massless.
Well, energy is one answer. But I would ask that if something has absolutely zero energy, does it even exist? Could it just be that all things are affected by gravity?
sirchick said:Would curved space time have potential energy in same way a spring is just waiting to be relased by the release of the matter in space time?
I ask because if gravity effects everything with energy, that would then mean it would effect itself which we know gravity doesn't effect gravity.
Drakkith said:Except that it does affect itself. This is why you cannot apply renormalization to gravity. (Or so I'm told)
sirchick said:How does it effect itself? If gravity effects energy and gravity can have energy, wouldn't there be a infinite space curve like a black hole only not effected by mass in a small area but rather - itself.

Do you have a reference for that?Chronos said:If gravity contributes to itself, you end up with free energy.
Yes, light does have a mass, but it is very small. According to Einstein's theory of relativity, mass and energy are equivalent, and light is a form of energy. Therefore, it can be said that light has a mass, although it is very small and difficult to measure.
Light's mass does not have a significant effect on gravity. This is because the mass of light is so small that it is negligible compared to the mass of larger objects, such as planets and stars, which have a much greater impact on gravity.
Yes, light can be affected by gravity. According to the theory of general relativity, gravity is the curvature of space-time caused by the presence of mass. As light travels through space, it follows the curvature of space created by massive objects, and this can result in the bending of light's path.
Light's mass does not affect its speed. According to the theory of special relativity, the speed of light in a vacuum is constant and does not change regardless of its energy or mass. This is one of the fundamental principles of modern physics.
No, light cannot escape from a black hole. A black hole is an object with such a strong gravitational pull that even light cannot escape from it. This is because the escape velocity, or the speed needed to overcome the gravitational pull, is greater than the speed of light, making it impossible for light to escape.
