Wormholes have intrigued both science fiction writers and theoretical physicists for decades. However, the wormholes considered in science fiction are very different from those seriously considered in modern theoretical physics; mainly due to the “macroscopic scale inviability” of the former. In recent years, there has been a resurgence of interest in wormhole geometry. Regarding quantum gravity, non-traversable and traversable wormhole geometries have recently been considered.

However, it was not until 1957 that the American theoretical physicist John Archibald Wheeler first used the term "wormhole". A wormhole is a hypothetical structure that connects two distinct points in space-time, "much like the actual tunnels dug by worms in a (Newtonian) apple." There are 3 types of wormholes, the first type of wormholes is an Einstein Rosen bridge, the second type is a string theory wormhole, and finally a man-made wormhole. All these wormholes are just math for now, but in the future, scientists might find one somewhere in the universe. Einstein Rosen bridges are the first type of wormhole to be theorized about. These wormholes are theorized to be in each black hole where the singularity is and lead to an infinite parallel universe where time is backwards, so in our universe things are sucked into the black hole but into the parallel universe things are vomited. of that, it's a white hole. But Einstein Rosen's bridges can't actually be crossed because it takes an infinite amount of energy and infinite time to cross them and close in the middle. So if you try to cross them, you will age and die, and your body will be stuck in the singularity forever. Also, since no one went to the parrel and you might not be able to get into a white hole either. So if we want to be able to travel across the universe in the blink of an eye, we'll need a different type of wormhole, a wormhole without a singularity to be able to pass through it. Fortunately, there is a type of wormhole that meets these standards. If string theory or one of its variants is the correct description of the universe, then string theory wormholes could be an easy way to navigate the universe. String theory wormholes are wormholes without singularities and were created in the first milliseconds after the big bang. These wormholes were formed by quantum fluctuations that created tears in space-time with cosmic strings running through them. As the universe rapidly expanded, these small tears in space-time scattered across the universe and the strings were tightened with them. These wormholes might be the closest thing to a wormhole we could get without creating one ourselves. However, there is a problem, the cosmic strings in these wormholes could break if one tries too hard on them and if they break, gravity will cause the wormhole to collapse into a black hole. Which makes them very dangerous and difficult to use because we won't be able to move it much, because if we tried to move it too much, the rope that holds the back, the gravity of the.
