The maths of String Theory (I really wonder if this can be proved) does point to the possibility of Parallel Universes. Personally I dont like this theory. I feel there is just one Universe that is extremely vast and most of it is unknown to us..

Space is expanding faster than the speed of light. The limit that applies to light and everything that started out slower than the speed of light is not placed on the expansion of space. When space expands between any two objects no 'G' force or acceleration is felt ... such as would be if either of, or both of the two objects were accelerating away or towards each other. Our acceleration is limited to less than the speed of light.
The expansion of space is not an acceleration, even tho objects are receding from each other, and therefore General Relativity places no limit on it at all.
