Theoretical physicist Michio Kaku explains string theory. The most interesting places in universe are beyond our reach with Einstein's theories, and that's where String Theory comes in. String theory takes us before the Big Bang to a multiverse of universes. (Maybe the Big Band was caused by the collision of universes or their fisioning.) Worm holes as time machines...in the memoir, that's exactly what childhood flashbacks seem to be.
"When you come up with a theory, you fall in love with the beauty the simplicity and elegance of it. But then you have to get a sheet of paper and pencil and crack out all the details. Hundreds and hundreds of pages. Because you have to prove it.", Michio Kaku
What we usually consider as impossible are simply engineering problems, there's no law of physics preventing them. Quote by Michio Kaku.
