Physicists claim that they can prove that there are more than 11 dimensions, can you explain this?

Question

What does this mean to our lives and deaths?

Why is this?

And if you can simply explain the idea about this?

I am clueless.

Answer 1

This is hard to explain if you know little on string theory and mathemactical models of strange and normal shapes of dimension 4th, 5th, etc. This question should help their were great answers given here: http://answers.yahoo.com/question/index;...

I will respond back with an edit if you are still confused.

Answer 2

The extra dimensions required by string theory are tiny spacial dimensions curled up inside our own.  There aren't places you can go to like on Buffy.  You're already in them.  They mean nothing to your life (or death).

String theory has not yet been proven correct (hopefully LISA and the LHC can help there) but it requires the extra dimensions to finally make general relativity and quantum mechanics agree.  They both work very well on their own scales, but don't agree inbetween - and that's a problem.

Answer 3

These extra dimensions are just curled around and not big enough to be noticed by us.  But what it means is that there's a lot more in heaven and earth than you have drempt of in your philosophy.

Answer 4

That statement is not quite accurate.  Some current theories, such as M theory and string theory would require there to be extra dimensions, but this has not yet been proven.  Here is a link to an interesting video explaining the different dimensions.  (it's about ten minutes long, and actually the first 5 I had heard hundreds of times before and if you have as well, might be kind of boring, but the last 5 minutes blew my mind)

Answer 5

String theory uses exactly eleven dimensions, not more than eleven, and they are small and in small areas, not the entire universe, so they have no effect upon our normal life. This theory is still mostly speculation. We are three-dimensional beings, so other dimensions are imperceptible to us. Extra dimensions have no measurable effects upon our lives or deaths.
