BLACK HOLE

I’ve talked about the speed of escape, and it’s  to be a major player in the ongoing events of the fall star-studded context. In short, it is the speed at which you need to throw something in the face of an object in order to escape. On Earth, the escape velocity is 11 km / sec. Find something that moves so fast, and it is no more; The Sun, which has a much lower gravity than the Earth, has an escape speed of more than 600km / sec. A neutron star, with the massive power, can have an escape of the speed of 150,000 km / sec - that's part of the speed of light! Keep that in mind, and let's go back to the center of the falling star. As it decreases, its gravitational pull becomes stronger. That means its escape speed is increasing. If it is equal to the neutron stars, the escape velocity is half the speed of light, but if it is more than 2.8 times the size of the Sun, the context will continue to fold. When its size decreased slightly, dropping about 18 km, an amazing thing happened: The speed of escape from its surface was equal to the speed of light.

And then, that's the problem, because in our Universe, nothing can move faster than the speed of light. Not rock, not rocket, not even light itself. When the star's core is reduced to a minimum, it cannot escape. It doesn't matter how it comes out, so it's like an endless HOD, and no light can come out, so it's DARK. We have to come up with a quick name for something like that. The black hole is the final shape in the backbone of the highest star. Anything that happens in a black hole LIVES in a black hole. That space, the one around the black hole where the escape speed is the speed of light, is called EVENT HORIZON for that reason. Any internal event cannot be identified. It is beyond our imagination. Black holes are confusing with our ideas of space and time. The mathematics and physics of black holes are so incredibly complex, that even after studying for a few decades, scientists still debate many of them. This has led to many misconceptions about them, too. All right, let's get this over with: The Sun can't be a black hole. It takes the stellar core at least three times the size of the Sun to overcome the pressure of neutron degradation.

That means the original star must have something like 20 times the weight of the Sun or more. So we are safe in that particular scifi situation. Here is another misconception: Many people think of black holes as cosmic cleaners, which absorb everything around them. But that is not true at all. They have a strong magnetic field, yes, but only if you are very close to one another. The power of the black hole comes from its weight, of course, but it is so important for its HELP. Or, in fact, its lack of size. From 150 million miles [150 million km], the Earth does not care whether the Sun is big or small. We are so far away that it doesn’t matter. It gets bigger when you get closer. Remember, from the gravitational force you feel in an object depends on how big your distance from its center. The closest you can find in the Sun is to touch it, it is more, about 700,000 kilometers from its center. The closer you get to its place, the MORE you are. Content OUTSIDE of your position is no longer degrading so the gravitational force you hear will actually decrease.

But if the Sun were to fall to the ground about 6 km across it would be a black hole. You can get closer to 700,000 miles [700,000 km], and as you do so you will feel a stronger and stronger pull as you approach it. So from a distance, a black hole, say, ten times the weight of the Sun can weigh you down just like a normal star with that weight. You can go around a dark hole, too, as long as you keep a safe distance between you and it. Surrounding the black hole of ten solar therapies would be like circling a star of ten ounces of solar energy… except that it is very hot and bright. The dark holes are strange enough without the misconceptions. Black holes also come in a variety of sizes. The type I was talking about has almost three times the value of the Sun, and it may be about ten or more times the weight of the Sun, if the parent star was large enough. We call these black holes as stellar-mass. In the event of a further collapse, the situation escalates, and the horizon of the event also increases. A black hole grows bigger.
