It has something to do with the m theory. It states that time existed before the creation of the universe and that we are just one universe of a multiverse. I saw it on the discovery chanlle. It requires the existance of I believe 11 dimensional space.
this is also referred to as string theory.
currently the main goal is to catch an image of a graviton particle (released within a particle excellorator [atom smasher], there are two large enough for this in the world, assuming the other has been built by now) as it is vanishing, gravitons are known to mysteriously make leaps or jumps to an unknown destination which may be, of many other possibilities, parallel dimensions or universes.
the 11 dimenional space thing is from quantum mechanics and sounds scary!
