Is The Existence of Parallel Universes Just Another Sci-Fi Fantasy?




Have you ever wondered what’s outside the world that we live in? When you’re in school, you learn about the basics of the planets surrounding the sun, the milky way, and even the big bang theory.  However, many physicists believe that there are multiple universes quite like our own floating around in space. With the studying of the different branches of physics such as relativistic, quantum, cosmological physics, unified, and computational physics, we can conclude that there is a variety of parallel universes. In the documentary above, it gives you more information on the study of parallel universes.

It’s safe to assume that people believe that there is only one universe because we are only able to discover, learn, and see what’s right in front of us. However, there is never one outcome to an experiment. According to The Hidden Reality, “The mathematics underlying quantum mechanics - or at least, one perspective on the math - suggests that all possible outcomes happen, each inhabiting its own separate universes.” (Greene, 5-6) Our universe has significant qualities and we shouldn’t ignore that these qualities that we failed to develop can be considered an advantage to another universe. Parallel universes are just like cars, they may all carry the same function, but there are many brands, colors, and features that make them stand out from each other. The picture on the right is the book cover of  The Hidden Reality.

There are many theories that are used to explain parallel universes. The bubble universes are an opening tucked within the super fast stretching cosmic expanse.  By examining temperature, pressure, and average density from different regions, you will see that the results are similar. They follow a uniform quite like our own.  Space is expanding everything and we don’t even notice it. It happens so fast that we don’t even feel it happening. Instead of the universe sticking to three dimensions - up/down, left/right, back/forth - a theory was created that the universe expands in all distances and that some may seem harder to see than others because of it’s size. This is known as the Kaluza-Klein theory. 


The String Theory is when particles become vibrations on a string, each creating a different mode and corresponding with a new particle. This theory has been used to test if parallel universes exist. However, dimensions may vary because of the difference of time in space. Theories help the realization of parallel universes become more realistic because these theories have been tried and research way past our time. 
These extra dimensions seems to go above our understanding. Michio Kaku explains, “Nowhere in our universe do we see objects suddenly disappearing or drifting off into another universe. This means that any higher dimensions, if they exist at all, must be smaller than an atom.” This states that we may be aware of what we can see, but we never take account of the smaller things that we can’t see or exist. It’s like peeking through a microscope and discovering the many different features that a fly has. You will never know unless you take a closer look. The video above is an interview between Michio Kaku, Brian Greene, and Dr. Lisa Randall discussing more about how string theory and m-theory relates to parallel universes.

The burning question is, “If parallel universes exist, why haven’t we contacted them?”. It’s not that simple. We still haven’t discover how to make cell phone reception work underground or cure cancer, do you think channeling another universe will be easier? People don’t just make these theories and conspiracies up from the top of their heads. When it comes to parallel universes, scientists have been working closely to find out how parallel universes are created and why they are unseen by the naked eye. They are closely examining every possible outcome and sometimes creating a new view on an old topic. Just look at the picture on the right and just imagine how huge our universe is. It's going to take a while before we start to contact and visit these parallel universes.

  1. Parallel Universes go beyond left/right, straight/back, and up/down. And yet, you can see in all those directions. You can also see sideways, but is that another parallel universe? No, it is not. The argument for parallel universes is an impossible one to make because you have no evidence in favor of them. Also, any argument for something you can’t see is as a rule of thumb, not true. How can you disprove something if you cannot see, hear, touch, smell, or taste it? By your logic, I could argue that the flying spaghetti monster is real, because I could say it is invisible, just like parallel universes. There is no scientific evidence of either, though.
    You say that since parallel universes are invisible, an object could simply go from being visible to invisible. I wonder, have you ever just thrown something and seen it disappear before your eyes? I very much doubt it. The best way to prove parallel universes exist is to show them so they are visible to the naked eye. If this isn’t possible, then how could you suggest that people can believe in them? The Kaluza-Klein theory is simply a myth, and cannot be proven.
