Recently, Australian astronomers discovered a superblack hole with a mass 3 billion times greater than that of the Sun.
Under normal circumstances, a black hole cannot exceed the mass of the sun dozens of times, but this black hole violates this convention, so the mass of this black hole is terrifying.
The existence of super black holes is already terrifying, and this black hole also has an amazing ability to devour other planets.
Take the mass of the earth as an example, because each planet has a certain mass, which is generally called the mass of the earth, so the speed of being swallowed by this super black hole every second on the earth is one earth per second.
This means that as long as a super-black hole appears near the solar system, it is fully capable of swallowing all the planets in the solar system, and may even swallow the sun eventually.
Therefore, as soon as it appears, it will surely cause panic among people across the globe.
But is it still far from a super-black hole appearing in the solar system?
Will it ever happen?
One, one second for one earth.
In ancient times, there was a super black hole, and now there is a super black hole, which is J1144, a super black hole with unprecedented mass in the Milky Way.
It was the emergence of this super black hole that made everything in the Milky Way incredible.
Because as a super black hole, its mass has already exceeded countless times that of the sun, and the mass of this super black hole has reached an astonishing 3 billion solar weights.
This means that if 3 billion is used as the number of "Earths" to be devoured per second, then J1144 can continue to devour at a rate of one Earth per second.
And as the devouring continues, the quality of J1144 will continue to grow, and records will continue to be set.
The discovery of J1144 also puzzled scientists, because under normal circumstances, the mass of a superblack hole would not exceed 20 times that of the Sun, which means that even with an unprecedented mass, it cannot exceed tens of thousands of times the mass of the Sun.
But J1144 defies this law and in every way, poses a huge puzzle to scientists.
Not only that, but J1144 has another amazing feature, which is that it is growing faster than other black holes in the Milky Way, and even in the last 9 billion years, it has grown at the fastest rate.
As such, it is also a candidate for the first super-black hole in the Milky Way.
And the peculiarity of J1144 also makes people wonder about the super black hole, why is it so massive and growing so fast?
What is the reason for this particular phenomenon?
Second, the crisis of proximity.
In the past, if the emergence of superblack holes was only in a small corner of the Milky Way, it would be fine, but now there is more than one superblack hole in the Milky Way, and there are at least 100 million wandering black holes in the Milky Way.
Only stars with sufficient mass can form black holes, but since the emergence of stars was not so common at the beginning of the universe, only relatively rare stars can give birth to black holes.
And the wandering black holes that appear in the Milky Way galaxy are even more surprising, that is, they still retain the mass of the original star.
The reason for this is that none of these black holes have experienced the death of protostars, so they do not eject matter, which means that humans can only detect their existence by observing the stars in them.
So there is no better way to observe the existence of black holes.
The closest black hole to the solar system is Gaia BH1, which is about 5,000 light-years away from Earth, so even if it is out of reach of humans, it will not pose a threat to humans.
Humans also accidentally discovered that there is a potential black hole only 80 light-years away from the solar system, which means that this black hole may be the closest black hole to the solar system.
Through numerous observations, the Gaia satellite has discovered a very different star, which is the star of the closest black hole to the solar system, which means that there is a high probability of a black hole near the solar system.
In addition, it is also difficult for humans to judge whether black holes are a threat to the Earth, so it is also difficult to judge their threat.
But this is not impossible, because the existence of black holes is full of unknowns, so no one knows whether they will pose a threat to the Earth.
Therefore, only by continuing to observe can we judge the threat of black holes to Earth.
3. The existence of black holes.
The existence of black holes is not a guess by humans themselves, but is based on the principles of astronomical observation and Einstein's theory of gravitational waves.
Before the discovery of black holes, humans believed that celestial telescopes were the only way to see the depths of the universe.
However, after Einstein proposed the theory of gravitational waves, the way humans observe the universe has changed dramatically, and in the future, everything in the depths of the universe can be observed by "listening".
But at that time, no one could discover that this was what Einstein called gravitational waves, until the first gravitational waves were discovered in the twenty-first century, which proved that human beings have another means of observing the universe, that is, by "listening".
However, in human observations, only the energy generated by the black hole can be found to be constantly devouring the star, and the loud sound is heard.
There are a billion wandering black holes in the Milky Way, and there may be wandering black holes around the Earth, but humans can only discover them by observing stars and accompanying stars.
And wandering black holes will not pose a threat to the large planets of the solar system, because these planets are huge and have formed stable orbits and will not be swallowed.
At the same time, these black holes have a mass similar to that of the Sun, so they are also not a threat to the Sun.
But the black holes that exist at the edge of the solar system are different, because these black holes are unprecedented super black holes, and their mass will pose a threat to the solar system.
Therefore, if an unprecedented super-black hole were to appear near the Sun, they would pose a threat to the Sun and even swallow it.
epilogue
Humanity's understanding of black holes is not very comprehensive, and we can only continue to work hard.
At present, humans are only observing black holes in the Milky Way, and in the deeper universe, black holes are still a mystery, so only by moving forward can we learn more about black holes.
