Hyperspace Theory

[Dust and Ashes]

I noticed that Captain_Jack_Sparrow listed himself as a theoretical physicist and was reminded of a book I read several years ago named Hyperspace by Micio Kaku. It was fascinating reading. IIRC he stated that he had "done the math" basically and that Einstein's theory was correct if you assumed there were 10 spacial dimensions.

He said that at some point the universe had split unequally into the 3 dimensions in which we live and the other 7 expanded and contracted to become so infinitely large and infintesimally small that we can't see or probe them, yet they completely surround us and even hold the unverse together at the smallest, sub-atomic level. I thought it was kind of interesting that we live in 3 while the other 7 are so far beyond us and yet so totally permeate everything. I took it as a mathematical revelation of God.

Kaku himself is apparently and atheist as he did mention that a "first Cause" was not necessary and cited a theory/law dealing with gasses and random movement.

I might be way off base with this but it came to mind and I thought I'd post it and ask if anyone had any opinions or updates on the theory and what it means, especially Cpt. Jack as he could no doubt come nearer understanding it that I could.

Peace and Love to you all in the boundless name of Jesus Christ.

sounds like an interesting thread, lets hope Capt Jack thinks so too

Probably a bunch a hooey. It is easy to write equasions but no evidence that they represent anything in the physical world.

Have you ever heard of the Quantum Theory of the String? It requires multiple dementions, one version which requires twenty some. Anyway, I don't know very much about it, and I should leave this thread because it's going to all be way over my head, but that might be something interesting to look in for this discussion.

I might have to check up on this since I find physics interesting even though I don't understand them at all.

Actually I think it might be tied to string theory. I remember he said the equation worked if you plugged in 10 dimensions or 26 but he went with 10 for his paper as 10 being a lower number seemed more probable.

That's what I meant.

The reason it is 10 dimensions is because that is the lowest number that allows you to formulate a string theory model that incorporates gravity.

That is what the book is about - it is a book on string theory.

The problem with treating gravity in a quantum mechanical manner is the infinities that appear in the equations. The standard way around infinities was to renormalise the equations (as in quantum electrodynamics) by the principle of gauge invariance. However, this is not possible with gravitational theory.

String theory is a possible way around this by treating fundamental particles as small vibrating strings as opposed to point particles. This also opens the way up to treating gravity as a quantum field like the other fundamental forces.

But so far the model needs 10 dimensions to mathematically work. Hence the reference to such in the OP's book.

Ah, the attempts at the unified field theory lead to even greater dimensions. Makes me wonder what is real and what is imagined in order to fit equations like the imaginary number (i), does it really exist? or , when talking about traveling faster than the speed of light, does a mass really go back in time, or does the world around it just appear to go back in time, until the particle stops?

These kind of thoughts can make my brain hurt, if I dwell on them too much. Props to the physicists that can think of these things, then try them out in real world experiments.

Oh wow, now that shook some rust loose in the old noggin. I used to really get into that stuff. I love physics and would love to go back to school and study it if only finances would cooperate. Pity they cancelled Project Orion. That was always my favorite and gave rise to many fantasies.
