We all have regrets, and most of us have wondered at some point if there was a way to go back in time to change the past or even just to be able to actually experience the past. While many people believe that time travel is impossible, thanks to some incredible physicists, these 10 amazing time travel theories indicate that time travel may actually be possible.
1. Tipler Cylinder
Also known as the infinite cylinder, this theory was first introduced by the astronomer Frank Tipler. He claims that within the space-time realm, there is a rotating cylinder that has infinite length and has a mass that’s 10 times that of the sun. He theorizes that if a spaceship entered the Tipler Cylinder, it would be able to travel through time.
