It seems that every week there’s a new book out about branes, M-theory, the multiverse, etc. by someone who doesn’t really seem to understand the difference between science and science fiction. This week’s example is Michio Kaku’s Parallel Worlds: A journey through creation, higher dimensions and the future of the cosmos.
My impressions of the book come from a few minutes spent flipping through it in the bookstore, so maybe I missed something. The only reference I saw to the lack of any experimental evidence for anything he is writing about was where he noted that we’ll need to travel faster than the speed of light to get to these parallel universes. So, we just have to wait for the development of warp drives. While references to experimental evidence were lacking, there were plenty of references to various science fiction novels.
I recently ran across a review of one of Kaku’s very similar other books, called “Hyperspace”. My favorite line in the review was near the end:
“Hopefully some time-traveler will go back and prevent this book from ever being published!”
