Today’s Lunch Break Theater is a good one. It is in five parts and is entitled, Cheat Sheet with Michio Kaku: Mysteries of The Universe.
Suppose you are out with a group of friends gazing at the night sky and someone says, did you know that they just found a black hole at the center of our galaxy? Someone else mentions dark matter. Another says the whole universe was smaller then an atom the instant before the big bang. No your friends aren’t Astro Physicists, they probably just have a good cheat sheet. Now it’s your turn.
