String Theory and the 11 dimensions? What is with the 7th+

[angledangle228]

I saw an animation of the ten dimensions and I understood and was able to really visualise everthing up to the seventh dimension and beyond.

Any advice for a deeper understading would be greatly appriciated.

Thanks

Hi angledangle 228;

Welcome to the forum. I hope you enjoy your stay here, and I'm looking forward to other posts and questions from you.

I have a theory regarding the hidden dimensions in my thread called An Idea. It shows a diagram as to how those 7/8 inner dimensions are able to be part of our 3 dimensional spatial reality. You can access it at: ( http://www.toequest.com/forum/your-t...2803-idea.html ). You'll have to access through the PDF file provided or just go to post #40 on that thread.

Any question or comments you may have can be posted on that thread.

BTW: M theory has 7 hidden dimensions and F theory has 8 hidden dimensions'

Best to you and again welcome,

Pat

P.S. The 7 hidden dimensions and the 3 spatial dimension and the 1 dimension of time make up the 11 dimensions of M theory

Thanks graybeard that was really helpful. It brought a sense of an actual mathematical basis to my understanding of string theory whereas before it was only an idea i had read about in non mathematical book! My comment would be this, whats is wrong with using QM for the very small and Relitivity for the very large... I mean, thats every thing. Right? large: check, small: check, everything.

Profpat, thanks for the post but I'm just in high school and I really have no idea what all of that means. Can you explain it without all of the math?

In fact that is what Science does ... it uses both.

Newton determined the Laws of Gravity.

Einstein, working on the electromagnetic force realised that Newtons concept was inaccurate. (I am only speaking very generally here) He corrected it.

If we only accept Newtons Laws, then all the modern day world would not have evolved to the current levels of technology. In other words we would have reached a limit.

As well there were many puzzling things that could not be explained by Newtons Laws. Something was wrong.

Einstein spent the rest of his life trying to re-concile Gravity with the Electromagnetic force, to no avail.

In fact two new forces, previously unknown were discovered. These forces are explained by Quantum Mechanics. Whats more, they are more related to the Electromagnetic force than Gravity is.

If we use QM and Relativity as you suggest, once again we face a limit, beyond which we cannot go. Once again there are puzzling things that do not fit the known Laws. Something is wrong.

To re-concile all four forces is the next goal. This is the purpose of a TOE or GUT.

The two books you first mentioned in another thread, are good 'starters' that will bring you to this understanding. Brian Greene's is probably the best for this.

You don't need to accept his 'view', that is a personal thing, but if you follow his explanations then you will be able to form your own 'view'. Its important to be able to read and not be influenced by the authors personal view, unless you choose to. Use your own analogies and imagination if the authors analogies seem confusing.

A great way to do this is by asking others on this forum.

I suppose what I am really saying, is read a lot, but keep an open mind
