One question...
Doesn't this all sound like a bunch of bull?
We live in the third dimension... 3-D. It's 3D because we can see things in depth, width, and length. Nothing else.
If there ARE other dimensions, we have no way of knowing that simply because none of us have been to any others. (that I know of)
So basically, this is all cool on writing, but its really nothing more than that. Just writing and theories.
The key thing here is you say we 'live' in the third dimension. that is incorrect. all that exists, exists in ALL dimensions. Literally, its the sum of all dimensions that make up 'you'.
The difference is, we as human beings can only PERCEIVE the first three dimensions. It is through math and controlled experiments + extremely sensitive equipment that can detect stuff that 'bleeds' into our 3 dimensions that they can be detected/proven.
After all, none of us can prove other dimensions exist, why have an entire branch of physics to figure it all out?
The 4+ dimensions are theorized to exist via mathematics. You need various new branches of science (physics, quantum physics, etc) to figure out how it works and how to use it.
As for proof of their existence... well, there's this expensive Large Hadron Collider thingy that the egghead scientists are trying to get working... and it was built exclusively to prove the existence of the dimensions we do not perceive.
What I find most interesting is that the 10-dimension superstring theory had maths and everything to explain the existance and state of matter and energy in the universe/multiverse but it failed to cover Gravity.
The M-theory adds the 11th dimension that covers that missing aspect and so far it seems to be holding nicely. The Hadron collider, if it detects what they expect to detect, would prove the m-theory as being highly likely to be correct..and man if that's so we could be seeing a MASSIVE explosion of technology for once the existence of something is proven the next step is how to use it.
Take a look at :
http://videos.howstuffworks.com/ted-conferences/7608-superstring-theory-explained-video.htmit explains the basics behind the different dimensions. Watch that first then jump to the original poster's link which covers each dimension by the numbers.
sucks that I can understand all this easily but im math stupid. Id've loved to have been a physicist
