I am currently a college student who has always had a love for math and science. I was recently thinking and discussing with some of my friends, how mass increases with speed as it gets closer to the speed of light. Then I started thinking about the concept of speed of light and how it is the fastest speed (at least to my knowledge) due to the fact that it doesn't need to push things out of the way to continue moving... Anyways, I started to think about that law that states, for each reaction there is an equal reaction. I was wondering what effect this has on the rules of light. I want to state, I am neither majoring in, nor am I taking any courses in physics. I don't have too much knowledge about a lot of physics, so go easy on me please :). Thanks.
