Is the book "Parallel Worlds" science or science fiction? While reading it I had the uneasy feeling of being out of my depth. It seemed as if all the "Star Trek" episodes I had watched were about to become true. Now quantum mechanics is weird but it does make my PC and mobile phone work. Do I have to accept the scientific speculation behind it? Up to a point, yes. After all I can't do the theoretical work behind books like this. Biology I can do. Particle physics is a tad expensive.
I found this blog by Plato the proof that I was out of my depth. So what shall I say of my impression of the book? The multiverse seems a possibilty to me. The contradiction that the unity is more than one. Language does not seem to help much before the big bang (or after the big crunch for that matter.) So creation and nirvana are both possible. Yet we have to plan our way out of this doomed universe, that will no longer be there billions of years in the future. Ecology tries to teach us to value what we have here. Kaku's science seems to be ultimately pessimistic. Maybe at root it is based on some fallacy. Are we missing something mind bogglingly obvious?
At times like this I always fall back on the veil of Isis. She let's us know what we need to know, in order to grow. Yet she still holds sway over the ultimate mystery. I know, that's mysticism. Guilty as charged. At least it helps me sleep at nights.
