@sethex.. i think u meant parallel universe theory.. if m-theory (string theory) is to be proved then there are 11 dimensions in the space time.. so yes maybe there can be parallel universe..
stephen hawking once shocked the physicists by claiming that black holes eats up matters/energy that enter it.. but as we know from the law of conservation that matter/energy can neither be created nor be destroyed.. so how the energy/matter inside black hole was getting destroyed..
then hawking proposed that they are not getting destroyed but rather getting leaked into another parallel universe.. balck holes acting as portal between universe.. and they are called parallel universe coz they are like parallel lines.. runs together but neer meets each other..
so that was a brief intro.. hope it helped.. if u can share more info i'll be happy.. and in my personal opinion the universe has endless possibilities.. but as a student of science i wont believe anything unitl proved..
