For a long time the wormhole has been a theory that rubs too much speculation due to its little possibility, although according to the mathematical theories raised by Einstein, it is possible that black holes exist in our universe.
A black hole is characterized by a portal that at the time of appearance has a short duration and this links two black holes in two different places of space, galaxy or universe.
The theory suggests that these wormholes can connect two points of the same universe or different universes and at different times.
Although Albert Einstein's theory of relativity predicts using mathematics that wormholes are an existential possibility, so far none have been discovered.
Even though science fiction is full of travel through wormholes,
Hypothetically having the possibility, one of the problems would be the size of this one, because it is speculated that these exist at levels of totally microscopic diameters, an approximated to 10-33 centimeters, but it is theorized that while the universe continues in expansion there are A possibility that these holes also do.
Despite being one of the theories that is most striking, it is very likely not correct, but this does not stop inspiring many people to consider all kinds of theories in order to give a correct solution to this "Possible" phenomenon, and who knows if Einstein was not so wrong and exist in our universe and are there for us to discover.
