I have thought about many different things in my life, but two things have always bothered me(I seem to come up with just the opposite answer- when compared to most people). I have not had what I think are sufficient answers to either, I was wondering what people here thought. The questions are
1. If matter is two dimensional, is it matter at all? I have asked this question many times, and I seem to always get the same answer... It has infinite density... how can matter exist if it has no volume? If does have infinite density then why doesn't(or wouldn't) the entire universe collapse from the infinite amount of gravity given off rom a hypothetical infinite density substance?
2. Does light have mass? I think so, but everyone else seems to think that light is pure energy. I think that anything that has gravity or momentum has to have mass. How can light warm anything, accellerate anything, or even exist without at least some mass? There are laws that prohibit the thought that light has no mass. I cannot see how(with my current knowledge of physics) light has no mass.
Please reply with your thoughts.

hanks for your time,
Phillip
