I never understood why we cannot go faster than the speed of light. There seemed to be no good reason other than that's what some equations say. Then I read an article on nasa.gov about warp drive and what they know about it outside the realm of science fiction and they explained as an aside why we can't go faster than the speed of light and I finally got it. The atoms that make up our physical selves and everything else are held together by electromagnetic fields, which is what light is made up of. We can't go faster than what holds everything together. This is amazing and sad, because I really wanted to go here.
