That IS gravitation...Gravitation is simply a phenomenon, what explains it is a theory, learn the difference.
At least 90% of people confuse those things, same thing with scientific theory being "just theory".
Gravitation can probably be described using quantum field theory(as exchange of virtual gravitons), or string theory.
I don't know much about string theory so I'm not gonna get into that
He is trying to say that gravity bends spacetime, gravity and space time are NOT two different things.
I said in my earlier post that spacetime is simply a way to explain what gravity is, and nothing else, and thats exactly what you also just said..
And I know what a theory is, just a formal way of saying "The best we have".

Spacetime is the medium that gravitational mass warps. Light does have momentum though, so why not consider it as matter. Gravity bends light, look up gravitational lensing of light. Black holes do suck in light, and the phenomenon gravity does exist, although it can be explained in different ways, hence the theory. You have little understanding of physics, and poor reasoning is no excuse for a false conclusion.
As for the reply to your edit, you might as well just give up on trying to learn anything because nothing can be proven right,id est by using your reasoning.
We don't consider light as matter... because it's not matter..
Just because it follows the rules of matter doesn't make it matter. Gravity bends light because because gravity isn't what Newton first thought it was.

Thankyou for clarifying what relativity is. This fool is trying to say what relativity is without even understanding it in the first place.
He said the same thing I said. Do you have something against me? Or are you actually trying to make a valid arguement, just failing really bad at it?
[Edit]
I know I shouldn't have said "proving" in my first post, it's a bit misleading.
Also, keep in mind that I'm a 16 year old KID, I'm not in college and I'm not in any honors classes at school. My physics teacher sometimes briefly mentions theories such as relativity etc etc, but rarely. Everything other then the basics is just me using my own head. I'm not a famous scientist so any misunderstandings are completely understandable in my opinion.
