The youngest black hole ever observed by humanity is the first one we know with an exact date of birth and can "watch it grow" – watching it form from a supernova explosion more than 50 million years ago and grow up in the 31 years since its birth.
Its iconic significance lies in:
1. Human beings have obtained the first set of measured data on the formation process of black holes, and can have a specimen and continue to observe the process of capturing the surrounding matter and accumulating its own mass. This will greatly help us gain insight into the mechanisms of black hole formation and development.
2. Because the mass of the stars that form this black hole is small, close to the lower limit of the mass of a star that can theoretically form a black hole, scientists may be able to more precisely delineate the statistical ratio of whether a supernova will form a neutron star or a black hole after a supernova explosion.
3. Referring to the X-ray characteristics of this black hole, we can find many other black holes - maybe they are widely distributed, but we didn't know that such X-ray sources were black holes.

There is a point in physical research, what is the formation of black holes, the concept of time and space, I am a layman, and I may know something about Hawking and Einstein when I look at ...... things
-
A black hole is a portal built by newcomers.
-
If someone breaks the silence, I will signal destruction.
-
Meaning, the end is not far off!
-
Black holes are very powerful beings, and black holes can devour everything in matter. Of course I know about black holes, and I think black holes are a very scary existence.
-
A very magical existence, the value of existence is particularly high, giving people a special feeling of mystery, special magic, and a certain degree of unknownness.
-
Black holes are a very magical existence in the universe, a kind of celestial body in the universe that can devour stars, and it can be said that it has a lot of energy.

In advance, the black hole, everyone's first reaction is that its attraction is extremely strong, even light cannot escape, it is a celestial body with a large curvature of space-time that light cannot escape from its event horizon, and with a strong gravitational attraction the entire galaxy spanning hundreds of thousands of light years orbiting it.
Black hole is a kind of celestial body that exists in the universe in the modern general theory of relativity, which cannot be directly observed, but its existence and mass can be known by indirect means. Today, we will introduce those objects that are more terrifying than black holes.
1. Giant gravitational sources (super black holes).
The attraction of black holes is already terrifying, but there is one that can attract more than black holes, also known as "super black holes".
A black hole can attract hundreds of thousands of light-years of galaxy bodies to orbit it, while a super-black hole can attract thousands of galaxies within 1.2 billion light-years to "fall" into it.
What is this concept? It's a super black hole equivalent to the energy of tens of thousands of black holes, have you ever seen a white blade with empty hands? That's pretty much it.
2. Supernova explosion (destruction together).
Supernova is the process by which some of the larger stars accumulate and contract after the evolution of iron, and collapse sharply inward to release energy released by impacting together.
A supernova explosion releases as much radiation energy as the sun has in its lifetime, and its brightness is 570 billion times that of the sun, and once ** is projected around at a speed of 30,000 kilometers per second, it will sweep everything around.
3. Gamma Storm (Terminator of Civilization Destruction).
Gamma rays have a strong penetrating power, extremely destructive to the human body, once irradiated by gamma rays, lesions and even death will occur, gamma ray burst is an instantaneous high-energy electromagnetic radiation, the energy released in a few seconds is equivalent to the energy released by hundreds of suns in a lifetime, if irradiated to the earth will reduce the ozone layer and produce acidic nitrogen oxides, thereby changing the chemical properties of the atmosphere, and eventually causing serious damage to the biosphere, there is a mass extinction event.
Scientists speculate that Earth's first mass extinction may have been caused by high-energy radiation from gamma bursts light years away.

Black holes are mysterious celestial bodies
Black holes have very peculiar properties
The inside of a black hole is full of possibilities
-
I don't know much about black holes, except that they are unfathomable "holes", and no one has been able to tell what exactly is inside them.
-
I feel that black holes are very wonderful and wonderful, and you don't know if there are unknown creatures in them. So it can arouse our curiosity.
-
We usually think of a black hole as a one-way valve that consumes everything it encounters. But they are also powerful engines, emitting radiation and sending high-energy projectiles into space.
You ask him if he still loves you, if he is love, then you ask him why he pushes, if his squeaky whine, then you break up with him directly, and sincerely wish you: I hope you can find your true love as soon as possible!
It's hard to say, maybe she's just thanking you for inviting you to dinner, but it doesn't rule out that she has an interesting feeling about you. You can choose to either confess to her and say that you like her, or you don't talk to her about feelings first, and see how the two of you develop in the future!
That's because he really likes you, don't think about the future, because he's afraid that you think too much, he will lose you because of it, he wants you to spend every day happily, he doesn't want you to always think about the things that will separate in the future, he means: as long as you love each other, no matter how long it takes, he will always be with you, he will meet you, you will always be together, not separated, and meet the sun tomorrow together. >>>More
It's hard to say, it may be that he has been hit by something, it may be a family matter, it may be that things at work are very unpleasant, so he feels that life is very ethereal, and he doesn't even know what he will do in the next second! He may have said this unintentionally, because when people are in a sad mood, they will also speak more pessimistically, which will cause you to misunderstand. >>>More
