As much as we might like to think that our collective knowledge has unlocked most of the mysteries of the universe, we’ve really only got a hold on a tiny fraction of the knowledge required to fully understand it all—and it’s a weak hold at best. But every once in a while a new theory comes along that completely upends everything we thought we knew and sends us down a new path that just might hold the key to all our unanswered questions. These theories often express ideas that are just too abstract or staggering to be accepted by the larger scientific community at the time, but, over the years, as more discoveries are made and certain pieces fall into place, sometimes even the wildest theories have been proven to be right all along.
While none of the hypothesis we present to you here have ever been conclusively verified, they haven’t been totally dismissed yet either. So why not decide for yourself which of these mind-blowing scientific theories you think has the most potential to pan out.
12. The Ekpyrotic Universe Theory
Providing an alternative to the widely accepted Big Bang theory, the ekpyrotic universe theory suggests that, unlike the Big Bang which supposedly began from a singularity, our universe is actually two universes that smashed into each other. It’s thought that this collision had the effect of “resetting” our universe and, after that point it started expanding just like in the Big Bang. However, instead of infinitely expanding forever, the theory asserts that one day the universe will begin to contract, inevitably leading to what some astrophysicists refer to as the Big Crunch. Then, all the speed and energy involved in the Big Crunch then creates another monumental collision, which results in the universe being reset again so the cycle can repeat itself for all eternity.
