Well if light doesn't have mass then how come it can't escape the gravitational pull of a black whole. why does the Earths gravitational affect its path.

I support your argument.

but it's not really pulling...it has to do with the curvature of space...isn't this a bit obvious?

actually, i guess it could go both ways...it could be pulled in, or it could be falling into the curve caused by the black hole...

Hmm.. A friend of mine told me that according to Physics, light is made up of particles, which bounce off objects (I understand this).
But Chemistry says that it's all wrong. unsure.gif

well i think there was an experiment done a long time ago where they shot a beam of light onto some gold foil and found that electrons from the foil were knocked out...i'm not too sure on this since it was a while since i've learned this...

anyways, i'm not sure if you're saying that light is made up of particles because it bounces off objects or if you're saying that it could be made up of particles because it bounces off objects...remember, sound waves bounce off objects, but they're only waves...

Light exhibits particle character in high energy regions and this is proved by photoelectric effect and black body radiation.

there is no doubt that light exhibits some behaviors of particles...
