According to one idea of quantum m, when the universe is faced with a decision at the quantum level that all decisions are made and the universe splits into new universe one where each decision is made. This quickly means more universes than we would ever be able to comprehend. Also leaving the possibility for universes to travel back in time, everyone have a universe where everything is perfect to them, a universe where a person could walk through walls there whole life, a universe where a sperm goes through the male into the female and impregnates her with while walking by, or a universe where it has already ended. However because of the huge number (and I mean fricking huge) universes there would need to be there are many that are similar. However as abstact as this sounds it does not mean that I believe in the new universe idea, its just some food for thought.
