How much do you know about black holes?
What would happen if you fell into black hole?Say one day you were exploring space, looking for a new planet for humans to inhabit, but came across a black hole and decided to check it out. Would you have any chance of survival? How would you get out? Will there be a shortcut to another universe? This is what if? And here's what would happen if you fell into a black home: Despite being black and a hole, a black hole is not a dark, empty space. In this theory of relativity, Einstein predicted how black holes are formed.
When a massive star dies, it leaves a smaller remnant core behind. If the course mass is at least three times greater than the mass of our son, gravity overwhelms all other forces and turns the core into a black hole. but don't let its name for you. A black hole isn't a hole at all, but rather a huge amount of matter packed into a very small space. Think of the sun, with its gravitational field twenty-eight times stronger. If you were to walk on the sun, you'd be twenty-eight times heavier than you are on earth. Now, imagine squeezing four sons into something that's just fifteen miles in diameter. the distance you can cover in a thirty-minute drive. What would the gravity be there? In a black hole, gravity is so strong that even light can't get out. That's why you'll never see one, but you can detect it from gamma ray bursts to the holidays. These birds, discovered by Stephen Hawking, now carry his name, Hawking Radiation. Stephen Hawking himself believes that black holes can be passages to other universes.
If you were to fall into one, would you find yourself in an alternate dimension? Every black hole has an event horizon, the point at which gravitational pull becomes so strong that you can't escape from it. to the point of no return. If you found yourself outside of that point, you'd see that stars are twisted around a perfect circle of darkness. As you start being pulled toward a black hole, you will be moving faster and faster, accelerated by the force of gravity. That is the first piece of bad news for you, brave space traveller. gravitational force of a black hole is very, very strong. If you fell feet first, your legs would feel a stronger gravitational pole than your head, and your body would be in part. The most common black holes are called stellar. They can stretch about nine miles across and be as heavy as twenty songs. If you were drawn towards a stellar black hole, you would be completely torn apart before you even reached the end. make sure to choose a supermassive one, the one that's a million times heavier than our son. In this case, your body would remain unharmed as you crossed the event horizon as gravity would be pulling both your feet into your head with almost the same strength. And if you're wondering where to find one, you don't have to look too far. There's one right at the centre of our Milky Way galaxy. Luckily, it's one hundred and sixty-five, quite a distance from us, and will not suck in either the sun nor the planets.
But don't pack your suitcase just yet. Crossing the event horizon is just the beginning of the challenge. There is a gravitational singularity at the black hole where density becomes infinite. You will be squashed into that centre and become one with the black hole. A person observing you from outside the event horizon, on the other hand, will see a very different picture as you fall into a black hole. They see you slowing down, getting dimmer, and the writer, in the end, just freezes, never crossing the eventually. This is because space and time in a black hole swap the rules at the event horizon. Time comes to a standstill, while space, on the other hand, moves forward. You wouldn't be able to turn around and escape the black hole any more than you could travel back in time, even when the black hole eventually died, emitting all the particles that had absorbed them, including your body. It would be impossible to tell whether those particles were Stephen Hawking, however, found a way in which the information about your body wouldn't be lost. He theorised that there were alternative universes with different histories. This means, in one reality, you fall into a black hole in the second one. There wasn't a black hole. From outside of the event horizon, it's impossible to know whether there's a black hole or not until you fall into it. If you cross the event horizon, if you happen to be in a reality where the black hole didn't exist, you would still be alive, just in a different universe. There would be no way for you to get back to us. Would you delay the possibility?
