Parallel Universes and MultiversesWe have all seen Rick and Morty and the Wizard of Oz, and how they both travel to different worlds. But what are those worlds that they travel to? Well, I did some research and found out that these worlds are called parallel universes.What are Parallel Universes?Some of you might be wondering, what is a parallel universes? Well I found out that parallel universes are theoretical fantasy/science-fiction universe that coexists with our universe but they have different laws of physics and they also have big or small changes. Some parallel universes could be identical to ours. For example in the Wizard of Oz when Dorothy travels to Oz, she meets the Lion, Tin Man and Scarecrow, they are that universes version of Zeke, Hunk, and Hickory. Another example is in Rick and Morty is when they travel to a different universe and there are three different earths and the one they chose to land on is super tiny so they can walk around it super fast. In both of them, the reason that the main characters don’t change is because they are the travelers. What are Multiverses?There is also something called a multiverse, which means multiple universes, that would mean that we have and infante number of universes. We don’t know if they even exist but some people believe that there are an infinite number of universes. If this theory is true it’s possible to have a universe where no life is possible, or a universe where you can only speak when the empire of cats allow you, or a similar universe with you sitting and reading this article. Scientists aren’t sure on what space-time looks like but they think that it is most likely flat and that it stretches out infinitely. But don’t you think that if space-time goes on forever it will end up repeating itself? Well, the answer to that is yes, if you look far enough you will find another one of you, in fact, millions of you, some might be doing the exact same thing as you well others may be wearing a different tee shirt or they might have a different hairstyle. As I said before some people believe in multiverses and these are the five reasons they think that.Reason One: Infinite Universes The first reason is parallel universes. The noticeable universe can only reach out as far as light had a chance to get to in the last 13.7 billion years since the big bang. Any space-time beyond that can be considered its own universe. Reason Two: Bubble Universes The second reason is bubble universes. In addition to multiple universes made by endless space time other universes could occur from a theory called eternal inflation. Inflation is the notion that the universe is expanding rapidly after the big bang. A cosmetologist named Alexander Vilenkin said that some pockets of space stop inflating while others continue. Therefore giving rise to many isolated bubble universes. Reason Three: Parallel UniversesThe third reason is parallel universes. Even though I have already talked about them they are also one of the reasons. It’s a reason because it’s thought that the parallel universes have collided and created big bangs therefore more universes.Reason Four: Daughter UniversesThe fourth reason is daughter universes. The theory of quantum mechanical suggests another way possible for multiple universes. It suggest that possible outcomes do happen but in their own separate universe. Much like parallel universes.Reason Five: Mathematical universes The fifth reason is mathematical universes. Some scientists suggest that the mathematical structure that makes up our universes isn’t the only option, and that all mathematical structures exist in their own universe. A cosmologist called Max Tegmark said “a mathematical structure is something that you can describe in a way that’s is completely independent if human baggage.” So, after everything i’ve told you about parallel universes and multiverses, and the five reason multiverses may actually exist. Do you believe in parallel universes and multiverses, I would think it would be really cool if the exist but they probably don’t.
