Black holes are the most mysterious elements that exist in the universe. Everything that happens inside it is the subject of multiple theories developed by scientists who study its composition.
They are known to be the most massive individual objects yet found. And that their gravitational field is so powerful that nothing, not even light, escapes them. That means that in order to escape from them you have to exceed the speed of light.
The most fanciful say that black holes are portals to another universe. While some dare to say that these objects can function as time machines.
Will it be possible to travel to the past or future thanks to these extremely massive objects? Probably not. But there are several kinds of hypotheses that explain how these black holes could be made to work as a tool for time travel.
However, they make it clear that this is a fantasy, because in the first place you don’t even have the necessary technology to be able to get close to one.
Suppose we can reach a black hole
In the supposed case that we can place ourselves near a black hole, which would be impossible since we would have to exceed the speed of light; So far the fastest traveling thing in the universe, let’s look at the possibilities in which one of these objects can function as a time machine.
But assuming that we developed this technology, when we approach a black hole, the gravitational force of it makes time in its surroundings go slower. It is said that a year within these galactic entities is 80 on Earth.
So, by being in its vicinity for a while, when we returned to Earth we would have taken an impressive leap in time. The only thing is that we couldn’t go back to the moment we left. Part of this theme is what happens in interstellarwhen Matthew McConaughey returns to see Murph.
