Humanity has long dreamed of traveling in time, but so far research on this topic has led nowhere. Although various stories of time travel appear on the Internet, there is currently no evidence that there is a way to create some kind of time machine that can move people to the past or future.
There are only hypotheses and versions of how portals can be found that can move people to other eras, and scientists are trying to find entry points to these portals, but modern scientists know too little about the structure of the Universe to be able to conduct an experiment on movement in the near future in time. Some scientists are seriously studying black holes, which could be a portal in the future. There is a hypothesis that when passing through a black hole, people or things can get into the future, but how realistic is this?
Experts say frankly that they know very little about the processes that lead to the appearance of black holes, as well as about what will happen to an object or living being when it gets into these space formations. The gravity of black holes is so enormous that even light cannot escape from them. Recently, two scientists named Javier Olmedo and Abhay Ashtekar decided to share their version of matter that for some reason falls into a black hole. They believe that matter can pass at the other end of the black hole, and then exit in the future, but from the white hole. Moreover, some scientists believe that time inside a black hole may be completely absent or stop, which also indicates the possibility of traveling into the future.
But if everything is clear with black holes, then what about the white hole hypothesis? This is another theory that has no evidence at the moment in the development of science. But if you only take into account the theory, then white holes could help solve the problem with the singularity that experts on black holes and time travel are talking about.
Further, scientists say that over time, black holes can transform into white holes, which will allow matter to escape and enter the future. A scientist named Carlo Rovelli, who is confident in the transformation of black holes into white ones, agrees with this hypothesis, but the amount of time it will take to change the structure of black holes into white ones is unknown.
It is worth noting that many scientists do not believe in the possibility of time travel, so they do not want to consider hypotheses and versions, but are based only on the evidence base. But in the past there were moments when most scientists did not believe in some of their hypotheses, but over time, these hypotheses were proved. So maybe time travel is quite real, but does it take time to study such processes?
