Scientists Prove the Possibility of Time Travel!?!?!? What You'll Read Will Amaze You...

A wormhole is a tunnel through the space-time continuum which allows for faster transit through the universe and the possibility of time travel. The theory of wormholes was created in 1934 by Albert Einstein and Nathan Rosen who used Einstein’s Theory of General Relativity to describe these bridges through space and time. Like the Holland Tunnel connecting New Jersey to Manhattan, a wormhole is a tunnel that would connect point A in the universe to point B. Imagine taking a map and folding it and then poking a hole through the center; this hole would be a wormhole. In warping space and time, wormholes provide a faster route from point A to point B in the vast universe. There are many different kinds of wormholes, like wormholes found in quantum foam which tend to be small tunnels. Meanwhile, Einstein-Rosen wormholes, like black holes, are massive and extremely dense celestial bodies that disrupt the fabric of space and time. It has been theorized that black holes themselves could be a form of wormholes.

The wormholes described have been theorized to connect two points in space, but they could also have the ability to connect two points in time itself. Einstein’s Theory of Relativity states that as objects begin to approach the speed of light, they distort time such that time runs slower for the object than it does for the object’s surroundings. Physicist Kip Thorne describes a hypothesis that would allow for time travel through a wormhole. In this example, there is a wormhole with one mouth on Earth and the other contained on a spaceship, attached kind of like a trailer to a truck. The spaceship travels for a few hours at speeds close to the speed of light, then heads back to Earth. This light travel ultimately creates a rift in time, as one end of the wormhole has traveled years in future due to the Theory of Relativity while the mouth that stayed on Earth is in current time. As a result, passing through this wormhole would be a way of traveling through time as you travel through one mouth in current time to another in the future.

Despite the great advancement wormholes would provide, it would be extremely hard to sustain one because wormholes are very unstable. They require large amounts of energy to hold them open, considering that they are tearing through the very fabric of space and time. Considering the amount of energy needed to keep a wormhole open, it is theorized that only wormholes would only be able to stay open if we pumped some sort of exotic matter into them. This exotic matter contains “negative energy density and a large negative pressure” (Redd). Thus, like the air inside of a balloon, this negative energy would be able to push outwards, negating the pressure pushing inwards that would ultimately force it to collapse on itself. Though these hypotheses have potential, the creation of a wormhole is far beyond the realm of our current technologies.
