Time Travel in Slaughterhouse 5

I thought our discussion the other day on time travel was very interesting, but I still think most of it is speculation and the use of random examples to explain a theory. But who knows, in an alternate universe, I might be wrong. I do find this topic quite stimulating, however, and I talked more about it with Chris later that day at lunch. He helped me understand it a little better as time travel pertains to the fourth dimmension and the speed of light. I think Kurt Vonnegut explored the early theories of time travel in his book Slaughterhouse Five, but I think he probably stumbled upon some of the things that we discovered in class by chance.
