I don’t know a lot about whether or not there is a parallel universe. I have thought a lot about it though. Like what if there is someone who is just like me light years away or what if there is a world that is the complete opposite of what we are living in right now? Scientists call it a multiverse. A place that is unable to be perceived directly. There are many alternative universes that carry their own different version of reality.
In a recent study done by the UK’s Royal Astronomical Society, they talked about a so called “cold-spot”. This is a cold patch of space seen in radiation of the Universe more than 13 billion years ago. This cold spot was first seen in 2004 by NASA’s WMAP satellite and then it was confirmed that it was indeed there in 2013 during ESA’s Planck mission. This cold spot has always been very puzzling. Many don’t think that it was produced during the making of the universe. But the latest study rules that out. This cold spot is actually an optical illusion that is produced by the lack of intervening galaxies. In other words, this spot is most likely the start of another universe that is colliding with ours.
The idea that there are many other universes throws a lot of what we think is true out of the window. Like, for example, physics. Physics explains the why of our universe. It explains why our universe takes the form it does and why certain quantities have the values that they do.
Paul Steinhardt from Princeton University helped develop the theory of inflation which is the theory of the origin of our universe. This theory completely goes against everything about the cold spot being an optical illusion made by a different universe colliding with ours. He recently went against his theory and said that “Our observable universe would be just one possibility out of a continuous spectrum of outcomes. So, we have not explained any feature of the universe by introducing inflation after all. We have just shifted the problem of the original big bang model to the inflationary model.”
A multiverse sounds kind of crazy, right? For all we know, we are a simulation for a bigger greater world. As a society, no one really knows if there is a parallel universe. There are theories and evidence to support both sides. If we do live in a multiverse though, there is probably an alternate version of me or you in another universe who has figured it out. Maybe someday soon will figure a way to tell us.
