Gravity is a theory as a whole. It's described in much detail in Einstein's theory of relativity. Again, I [u]know[/u] what I'm talking about. I have a degree in biology, and recently got a minor in Chemistry with a bit of emphasis in Physics. I'm not going to waste my time on someone who doesn't think Evolution is true just because it's a theory. Seriously, if a scientist is telling you how science works and you claim that middle school science terms are more accurate than actual science terms, then there is something definitely wrong with the education you received. I study science on a daily basis. Here, let me add emphasis on this tl;dr: [b][u][i]I KNOW WHAT I AM TALKING ABOUT[/i][/u][/b]. This will be my last reply to you because I don't want to be an asshole to a child.
