Michio Kaku | Why do we think that?
"Why do we think that? Because we have a theory called string theory, it is fantastic it is incredible. It has astounded the world of mathematics, and physics and now you can't move in the physics world without bumping into somebody who wants to talk about the 10th Dimension the 11th Dimension the Multiverse hyperspace time travel. All the things that were once considered science fiction are now centerpiece in our understanding of the nature of everything."
