HI!, i'm new here, and i wanted to say that this site is great, so many things to read, so little time.

Ok. havin said that i want to get to the question/commentary. I just read Dr. Michio Kaku's book "Hyperspace", frankly i thought it was great, and since i don't have that much knowledge on the subkect, i wanted to get your opinions on it (if have or haven't read it), just wanted to see what the people who really know this stuff think...thanks, see ya.

I have that book siting on my shelf at home collecting dust! I think I read it some time ago then again I can't remember. It was about higher dimensions right?

Yes, in a nutshell that's what it is about, allthough it touches various subjects, all related somehow.:cool:

It's a reasonable non-mathematical introduction to some of the ideas of string theory. It leaves out a lot of detail, but then again, string theory is a difficult subject - particularly without the maths.

It had that thing about the 2D people right?

As much as I know, Michio Kaku supports the idea of the 11-dimensional space. It is the so called M-theory that should unite 10-dimensional super-gravity theories with super-string theories.
To me it all looks very dim and unclear.

i personally believe it`s on the right track, but there are other theories that involve the geometry of spinors and orbifold space ,also the new theories of knots, to give rise to the properties of particles ( and dimentions)...

To me it all looks very dim and unclear.What I understand from my reading of superstring theory (but not saying you are wrong) is that the several theories they have point to an underlying theory dubbed M-theory. Not much is known about M-theory at this time. The math is extraordinarily difficult.

kind regards

I'd recommend 'The Elegant Universe' by Brian Greene as a good description of strings, superstrings, M-theory etc for the 'numerate educated layman' (like me). Obviously some things are lost if one doesn't know the detailed mathematical models (I certainly don't) but Greene's book gives a decent insight into current theories.

Cheers,
