Hey, you think the black hole is a black hole, and you're done sucking everything in? The recent re-detection of gravity waves has given the black hole a new wave of presence, and the universe's "mystics" have a lot of cold knowledge
The black hole is not really a hole
A lot of people listen to the name black hole, and they think it's definitely a hole. Wrong! It is indeed a heavenly heaven. You think, if you compress the radius of the sun to 2. 9 kilometers, the sun becomes a black hole. Can you still call it a hole? It's called a black hole just because it's so gravitational that it can't even get out of light. And, if we compress the earth to peanut size, it can turn into a black hole. If the black hole is real, then the earth becomes a peanut hole. So don't let that name get to you. The black hole isn't what we thought it was. Do you still insist that a black hole is an ordinary hole
Besides, it's a lot bigger than i thought. The center of many galaxies in the universe is a supermassive black hole, like the center of the phoenix galaxy, which contains 20 million sun mass. This mass, the gravity it produces, is naturally super strong, and the surrounding matter is sucked to death. How can this be a simple hole? So, the idea of a black hole as an ordinary hole really needs to be thrown away。
In conclusion, the black hole, though called a hole, is an object of supergravity and incredible mass, so don't be misled by names
Black holes aren't so black
We all know the black hole because the light can't get out. But it's worth noting that that doesn't mean it can't really be seen at all. While the black hole itself cannot be observed directly, its existence and quality can be seen indirectly, as well as its impact on other things. It's like this gravitational wave that's been detected because of the strong space-time vibrations from two black holes. If the black hole is completely black and nothing can be found, where did these discoveries come from? Can it always be hidden from us? Obviously not。
Moreover, as early as 1974, stephen hawking had introduced the “hodgin radiation” theory, saying that black holes would shrink and disappear because of radiation. What does that mean? It means that the black hole itself is changing, and it's not the same kind of black end. If it's pure black, nothing can be done, then there's still radiation? Can you disappear? So, the black hole's "black" isn't that simple, it has its own "black secret" and is waiting for us to explore it further。
So don't think the black hole is pure black. It has a lot of hidden attributes that we can understand
Where's the information in the black hole? It's a question mark
Everyone knows things go into a black hole as if they were dead. But what about the information? In 1974, hawking indicated that the black hole had spread radiation without carrying any information. If a black hole releases particles, it loses mass, shrinks and gets warmer, gives enough time and the amount of heat, the black hole disappears completely, but the information thrown in is gone? This is so weird. If you burn a book and you can't see it, the message that makes it is still in smoke and ashes. What happened to the black hole? Did it just disappear? That doesn't make sense。
More crucially, scientists have been thinking about this, after all, about a deeper understanding of the universe. If the information is gone, then many theories about the universe might have to be reconsidered. This black hole information paradox is a painful and fascinating question. Maybe one day we'll find something new to solve this mystery, and then we'll have to take a new step up our knowledge of the black hole. Don't you wonder what's going on in this black hole
Anyway, the information in the black hole is still a mystery, waiting for more exploration to solve it

All right, these three black holes are a dead end. The black hole is truly a super mysterious and fascinating existence in the universe, and every time you learn more about it, you feel awe of the vast universe. Next time we talk about black holes, we'll have a lot to talk about, and we won't be able to say the jokes。
But then again, the universe is so big, the secrets of black holes must be a lot more than we can dig. What else do you think we'll find in the future? Let's talk。
