Our Amazing Universe

Elí S. Sánchez

Since I got accepted in this university I got great interest in a theory I had heard, the theory of the Multiverse. The multiverse –also called parallel universe- is a theory that explains that there is a set of multiple universes that include everything that physically exists. After reading some research papers and other articles I got really shocked by quantum physics. It tries to explain the behavior of even smaller particles such as protons, neutrons, electrons, and even the particles that make up those particles, like photons. Instead of having a fixed place for the electrons to be, quantum physics gives us a statistical probability of the electrons location at any one moment. This means that in this universe I’m here writing this essay, but maybe in other universe I’m out having some fun with friends, or even I’m on other college taking another career.

Thinking about all this, I came up with this question, if all this is right, then the classic physics course I’m taking is wrong? Then I realized that the classic physics is wrong only if we are dealing with very small or very small, and whit this I mean VERY small and VERY fast things. Going back to the multiverses, them currently cannot be proven to exist, but this theory is widely accepted because of its solid base. Max Tegmark, a cosmologist, came with a taxonomy of the universes that exists. He states that there are four (4) types of parallel universes.

The Level I multiverses implies that surely, somewhere else out there, are other planets exactly like Earth. In fact, an infinite universe would have infinitely many planets, and on some of them, the events that play out would be virtually identical to those on our own Earth. We can’t see these other universes because if light started at the moment of the big bang, then we can only see no further than about 14 billion light-years (and counting due to the expansion of the universe). Which means that is virtually impossible to travel to those universes because we can’t go faster than light. 

The Level II multiverses consists of universes that continues to expand eternally, consequently producing an infinte number of universes, making the space between us and other universes bigger at a rate faster than the speed of light. Again, making them virtually unreachable.

The Level III multiverses. This is a result of the many worlds interpretation from quantum physics. This is the multiverse that I’ve heard a lot out there. It states that every moment in everybody’s life the universe split in all the possible decisions we can take. That is to say that there is an infinite number of “futures” us with the result of every quantum possibility. May be there’s two identical universes with the only difference of 1/10 of a nanometer wider crater on the moon. 

Level IV multiverses are the strangest ones. They would have fundamentally different mathematical laws of nature. In other words every possible universe someone can imagine exists.

In conclusion, quantum physics and multiverses are interesting as their complexity. Maybe in future someone will come out with a machine to interact with other universes; maybe someone in other universe is already interacting with universes. I have always thought that there is no limit, if we put a limit to our imagination, may be we’ll never find the real answer to our questions.
