What is a Wormhole?- Explained

A wormhole is a hypothetical path through space-time that might possibly generate shortcuts for long space voyages across the cosmos. The ideas of Wormholes are projected by Einstein’s theory of general relativity. These theoretical concepts of wormholes also propose the dangers of rapid collapse, high radiation and unsafe interaction with exotic matter.

The Wormhole theory

In 1935, famous physicists Albert Einstein and Nathan Rosen by using the theory of general relativity suggested the presence of "bridges" through space-time. These routes, called Einstein-Rosen bridges or wormholes, join two dissimilar points in space-time, theoretically generating a shortcut that might reduce travel time and distance also. Wormholes comprise two openings, with a tunnel linking the two openings. The openings would most probably be spheroidal. The openings might be a straight stretch, but it might also wind around, taking a lengthier route than a straighter route might require. Einstein's famous theory of general relativity mathematically forecasts the presence of wormholes, but none have been discovered or detected yet. A negative mass wormhole might be detected by the way its gravity disturbs light that passes by. Definite solutions of general relativity allow for the presence of wormholes where the opening of each is a black hole. Nonetheless, a naturally existing black hole, made by the collapse of a giant dying star, does not by itself generates a wormhole.

Through the wormhole

Science fiction is jam-packed with fictions of roaming through wormholes. But the actuality of such travel is more complex then presented in films, and not just as we've yet to spot one. The very first difficulty is size. Ancient wormholes are projected to occur on microscopic levels, about 10–33 centimeters. Still, as the universe inflates, it is probable that some may have been pushed or forced to larger sizes.

Another problem comes from constancy. The projected Einstein-Rosen wormholes would be unworkable for travel as they collapse rapidly. But current research found that a wormhole comprising "exotic" matter might stay open and fixed for extended periods of time.


Exotic matter, which should not be mixed up with dark matter or even with antimatter, comprises of negative energy density and a huge negative pressure. Such type of matter has only been seen in the actions of definite vacuum states as part of quantum field theory.

If a wormhole enclosed enough exotic matter, whether naturally taking place or artificially added, it might theoretically be used as a technique of sending information or even travelers through space.

Wormholes may perhaps not only join two distinct areas within the universe, they could also link two different universes. Likewise, some researchers have speculated that if one opening of a wormhole is relocated in a precise manner, it could permit for time travel. Though, British cosmologist Stephen Hawking has claimed that such use is not probable.

Even though adding exotic matter to a wormhole might stabilize it to the peak that human travelers could travel securely through it, there is still the probability that the addition of "regular" matter would be appropriate to destabilize the gateway.

Today's machinery is not capable enough to increase or stabilize wormholes, even if they could be discovered. Nevertheless, scientists carry on exploring the conception as a technique of space travel with the optimism that technology will ultimately be able to operate them.
