Besides the overuse of the color purple, this video that includes Physicist Dr. Jana Levin, does a decent job at trying to paint a picture of how the universe was created. Still, I always tend to braincramp when I hear people say that before the Big Bang, there was "nothing". Well, what exactly does the universe expand into upon the instant of the Big Bang?? Needless to say, there are a few other cool theories explained by Janna.... The universe bouncing from a previous history into this cosmos, or multi/mega universes?! Eff'd!
