What would happen if you traveled through a black hole?

A copy of the video follows.

Narrator: Black holes are at the crossroads between science fiction and science facts. On the one hand, scientists have seen real black holes in action that consume unsuspecting stars that are passing too close. But where reality ends and fiction begins, there is the edge of a black hole – a place called the event horizon, where a spaceship has never gone.

What happens beyond this border within a black hole can only be suspected. Scientists agree that when you travel far enough into a black hole, gravity eventually becomes so powerful that you destroy everything in your path. But science fiction films are more optimistic and show black holes as portals through space and time or transitions to other dimensions. And it turns out that some scientists now believe that the science fiction buffs encounter something. Black holes may be suitable for hyperspace travel. it only takes the right style black hole.

In the middle of each black hole is a point of infinite density, the singularity. It's what gives black holes their strong appeal. For decades, scientists thought that the singularities are all the same, so everything that crossed the horizon of the event is destroyed in the same way: by stretching and pulling like an infinitely long piece of spaghetti.

However, this changed in the early 1

990s when several research teams in Canada and the US discovered a second singularity known as the "mass inflation singularity". It still has a strong appeal, but it would only stretch you by a finite amount and possibly NOT kill you, which means you could survive the journey through a black hole. Specifically, through a large, rotating black hole where such singularities exist.

Now, astronomers obviously can not travel through a black hole to test this theory. The best place to test this is indeed the supermassive black hole at the center of our home galaxy, the Milky Way, which is 27,000 light-years away. Not practically nearby.

That's why scientists are doing computer simulations to see what would happen if we reached an isolated, rotating black hole. Now a team of scientists at UMass Dartmouth and Georgia Gwinnett College has done just that.

Lior Burko: "You would feel a slight increase in temperature, but it would not be a dramatic increase, it's just that you do not have enough time to respond to the very strong forces, it would just go quickly through you. "

Narrator: He added that passing a faint singularity is like a quick fingering through a candle flame, which is 1,000 degrees Celsius. If you hold your finger in the flame long enough, you will be burned, but let it through quickly, and you will hardly feel anything. If you go through a weak singularity with the right pace, the right moment, and the right time, you may not feel much.

What exactly happens when you get to the other side, no one really knows, but Burko has his own ideas. He says that one possibility is that we might come to another remote part of our galaxy, possibly light-years away from planets or stars, but a second, and perhaps more intriguing, possibility would be for us to arrive in another galaxy altogether. That is if you even come so far.

Scientists say there is a need for further research before we approach a successful breakthrough through a black hole. But if we're ready, one of the safest passes could be the supermassive black hole at the center of our galaxy Sagittarius A *, and it could just be our Milky Way ticket.
