Interdimensional Movement; Time Properties.

This completely blew me away today. I was talking to my Astronomy prof post-class, I had some extra questions for him simply out of curiosity for the subject matter. As simply as possible…

After the big bang 4 major forces came to be (in order of weakest to strongest): gravity, electromagnetic, weak, and strong. Now gravity’s source is mass. Gravity, and I always thought the opposite of this, is the weakest of the four. There are a total of 11 dimensions, but human beings can only see 3 of them. Via the universal “String Theory” (that every particle is a loop, EXCEPT gravity, which is a string), gravity can actually escape certain dimensions because of its shape. So gravity moves in and out of these 11 dimensions, whilst the other forces, although they may be present in all 11, must stay put where they’re at. Scientists are doing all sorts of test to try to prove this; that gravity can actually escape/wander different dimensions. So, I asked, if we were able to (although this is hypothetical, because it would be impossible for now) attach something or someone to the actual force of gravity, that object could transcend each dimension with the gravity itself? “Yes”.

Another fact worth noting is that time is relative to mass. Meaning time moves slower on say Jupiter, and faster on the moon. And I don’t mean it takes longer for a Jupiter revolution around the Sun. I mean literally time moves slower. If someone lived on the Moon, their cells would deteriorate faster than on Earth. Which is absolutely insane, and actually puts the end of 2001: A Space Odyssey into perspective.

Extra Info (not mine):

Another possibility is that we are “stuck” in a 3+1 dimensional (i.e. three spatial dimensions plus the time dimension) subspace of the full universe. This subspace is supposed to be a D-brane, hence this is known as a braneworld theory. Many people believe that some combination of the two ideas — compactification and branes — will ultimately yield the most realistic theory.

In either case, gravity acting in the hidden dimensions affects other non-gravitational forces such as electromagnetism. In fact, Kaluza and Klein’s early work demonstrated that general relativity with four large dimensions and one small dimension actually predicts the existence of electromagnetism. However, because of the nature of Calabi-Yau manifolds, no new forces appear from the small dimensions, but their shape has a profound effect on how the forces between the strings appear in our four dimensional universe. In principle, therefore, it is possible to deduce the nature of those extra dimensions by requiring consistency with the standard model, but this is not yet a practical possibility. It is also possible to extract information regarding the hidden dimensions by precision tests of gravity, but so far these have only put upper limitations on the size of such hidden dimensions.
