There’s a lot of things about this planet and the universe that we don’t understand. No matter how much we think we know it all, we pretty much never will. Some things we aren’t sure about can be fascinating, and others are just crazy. These Reddit users brought up some of the craziest theories you’ll ever hear, and some of them might actually scare you. Check them out!
So there is this surgery people get that separates the connection between the left and right side of the brain. People who get this done often have this strange thing happen where their left hand gets a mind of its own. For example, if you lay a bunch of differently colored objects out in front of them and ask them to pick the one that’s their favorite color, they will pick up two that are different colors.
People hypothesize that there may be a second consciousness living on the right side of your brain, but does not have the ability to communicate. (Pizza_John_Marston)
Although not particularly scary, still pretty terrifying when you think about it.
The “Big Bounce” theory.
There’s a Kurzgesagt video that goes into it briefly:
What it states is that if the big bang occurred from nothing, then there will be no changing factor to make a difference in what is created when it happens. This means that when our universe ends and another is created, it will be created in the exact same way, with the exact same galaxies, planets, species and so on. If this is true, our entire universe is in an endless cycle of creating and destroying itself, and you will be born into every universe, endlessly. (Ravenbutt)
The Great Filter
The Great Filter, an extension of the Fermi Paradox. There are large events that filter out which species “make it.” Humanity has either made it past more than almost anything else in the galaxy, or we’ve yet to hit it and the human race will crumble in the forseeable future. (FHG3826)
