Hello all. I have a quick question regarding gravity and I was wondering if someone could explain it to me in laymans terms, since I do not possesses the mathematical background to understand higher physics.
According to Einstein, if gravity is simply the "fabric" of spacetime -- akin to a 2-dimensional rubber sheet where matter resting on top warps the sheet, and creating the sensation of gravitational forces -- then how is it possible then that graviton particles should exist?
It seems counter-intuitive to think that the background fabric of spacetime could have particles acting as carriers of the force, since the "warping" of space itself is the only explanation needed to explain gravity. After all, if we use the rubber sheet analogy, there is no need to explain gravity by introducing particles, since the presense of matter on the sheet is more than enough to account for the gravitational force.
Thanks for taking the time to read this, can someone quickly explain it? I am very confused!
