- Parallel Universes Original
Considers the scientific theory of parallel universes, suggesting that they could exist less than one millimetre away from us and that our gravity is just a weak signal leaking out of another universe into ours. Serious research began when superstring theory, hyperspace and dark matter made physicists realise that the three dimensions that were previously used to describe the universe were not enough and that there are actually eleven dimensions. Also examines the theory that our universe was originally created when two floating universes collided millions of years ago and considers the risks of such an event happening again.
