I'm an engineer, not a physicist, so you'll forgive my pre-uni knowledge of all things physics. I was discussing electromagnetic fields with someone, we got into it, photons being messenger particles, then onto gravitation and gravitons and so on.
I got slightly confused by a few things. Photons have no mass and aren't affected by gravity (they have no gravitons I guess), but they are affected by gravitational lensing, because space-time is curved. But then what's the point of the graviton particle? If there was only one mass object in the universe, and it was bending EM waves around it, but it wasn't doing this with gravitons, what do gravitons actually do (in theory)?
Where am I going wrong? Thanks,
Nenad
