Though we live in the universe, there's still a heck of a lot we don't know about it. Even with that limited information, there are dozens of scientific theories about space and time to explain away the greatest mysteries of our intergalactic neighborhood. Not all of them are pleasant, though. Some of them are downright terrifying, and even more highlight just how alone we are out in this void we call space.
We know what you're thinking: they're just theories, why should I be creeped out? Well, these scientific theories about the universe have been devised by some of the greatest minds in the fields of cosmology and physics. These guys have a pretty good idea what they're talking about... and what they're talking about ain't pretty. So sit back and prepare to stare into the void.
White Holes Are Apparently a Thing
Everyone knows about black holes, but apparently their opposites exist. Unlike their darker cousins, white holes cannot be entered, but matter and light are constantly escaping from them. The real creepy part is, where is all this stuff coming from? Could it be the exit of a black hole?
The Big Bang Came from Already-Existing Universes
String theory says that there shouldn't be just one universe, but a whole lot of them floating out there. How was ours crafted? Well, speculation is that the Big Bang came from other universes splitting apart or crashing together. Does it make us less unique? Sure. But look on the bright side - if that's true, that means we're not as alone as we thought.
Time Is Literally Running Out
While some scientists believe the expansion of the universe is accelerating, some theorize that distant celestial bodies only seem that way because we're looking back in time to see them (remember, it takes a while for their light to reach us). So, that means that they were moving faster in the past than they are in now... which means time is slowing down.
How much is it slowing down? We don't know - but if the theory is correct it may just slow to a stop.
The Universe Is a Computer Simulation
The Matrix may be real, according to Oxford philosopher Nick Bostrum. He suggested that an advanced civilization, with enough computer power, could run a simulation elaborate enough to create artificial minds, physics, and everything else in our universe. Right now, you might just be a really complex set of 1s and 0s.
