Fascinating Wormholes

Wormholes are theorized tunnels which go through space-time, sort of like those at water parks, but instead of going and ending at a pool these tunnels end at a different universe or a different place in our universe millions of light years away.

The simplest way of explaining how a wormhole works is by imagining space-time as a piece of paper. For example, on a paper we want to travel from point A to point B. The fastest way is of course going in a straight line, right? WRONG, remember the paper is space-time, so the fastest way would be to fold the paper and align the dots and then create a hole going through them, then — BOOM because of the hole we can now travel from point A to B faster than the speed of light. Space-Time can be bent because of Einstein’s theory of relativity which states that space is not a hard solid but more an air mattress which can be bent, torn and patched together. What we just saw was an example of a Man-Made Wormholes. There are two others types, Einstein – Rosen Bridges and String Theory Wormholes.

Einstein – Rosen Bridges were first introduced in The Theory of General Relativity, which stated that every black hole is kind of a wormhole where the other end is a white hole. This means that when one crosses the horizon, one ends up in a whole new location in our universe or another one. The other end is known as a white hole. Only problem is that it would take a person an infinite amount of time to come out from the other side thus making it not traversable.

If String Theory states the correct description of our universe then it would mean that there are many wormholes just waiting to be discovered. In the early universe Space – Time Quantum Fluctuations might already have creative traversable wormholes, going through these are cosmic strings. When the big bang happened, these strings were pulled billions of light years away thus making wormholes. You might wonder how we can find these wormholes and use them to travel, well… it's a bit hard

The studies conducted at the University of Buffalo point towards a wormhole existing near Sagittarius A*. Physicist Dejan Stojkovic, the co-author of this study said in a statement that “If you have two stars, one on each side of the wormhole, the star on our side should feel the gravitational influence of the star that’s on the other side. The gravitational flux will go through the wormhole. So if you map the expected orbit of a star around Sagittarius A*, you should see deviations from that orbit if there is a wormhole there with a star on the other side. 

Even if we ever found a wormhole which was traversable, it would have to be extremely large and stable so that the wormhole stays open all the time. Realistically we would need something called negative energy to keep wormholes open and at this point in time we don’t know how to control or acquire it.
