It's really amazing. They do a good job of explaining difficult things. I found the idea of time being like a three dimensional cross-section to be very deep.
Unfortunately, it's as far as I can tell pure fantasy. Sure, you can throw in fancy words like "string theory" and "extra dimensions", but it doesn't make it any more true. For one thing, there's little if any experimental support for string theory yet. For another, what this webpage says doesn't line up with anything, really, leading me to think this is complete bullshit. The jumping through time and possible worlds stuff is made up.
This guy could probably be a decent science fiction writer. He's certainly not a physicist. Read the two first reviews at amazon.
Unlike Hawking, who is a real physicist who not only has a brilliant grasp of current physics but has contributed to it, this guy is nothing but a pretender. He presents his work as though it's popular science while in fact it is the author's understanding of popular science sprinkled with pure fantasy.
I've seen this website pop up in web forums from time to time, and it never fails to astonish and impress lay readers. I'm nowhere near a scientist, yet I can clearly see that this is bunk. Why can't you?
maybe you are right and this guy isn't a real physicist, anyway the theory of multiple dimensions is promoted, and even modified by Stephen Hawking, he supports the theorie of membrane universes and the cord theorie, gives so much sense to the existense of multiple dimensions.
Yes i have noted that this guy is some wrong because according to Hawking theories, there may be 11 dimensions
