The Multiverse Theory

Anyone who has not spent the last ten years on a desert island, has at least once heard of “the multiverse”, or parallel universes. As many of us have seen, parallel words, in theory, are worlds very similar to ours, with little (or in some cases, large) changes or differences. The multiverse theory speculates that there could exist an infinite number of these alternate realities.
What’s the point? In a parallel reality you have already killed the dinosaurs, and you are lying under the ground at a depth of eight feet (because that’s what happened there.) In the other you might be a powerful king. In another you might never have even been born since your parents never met. Now that’s a memorable image.
