How terrible is the biggest black hole in the universe? Scientists have discovered a huge black hole 40 billion times the mass of the sun in the bar spiral galaxy Cetus, about 700 million light-years away from earth.
It’s the black hole at the center of homberg 15A.
And the story of it begins with the world’s most powerful Observatory, the parina observatory.
In June 2019, a joint working group of astronomers came to the parina Observatory in southern Chile, and began a one month academic research on the homberg 15A Galaxy 700 million light-years away.
According to the telescope image, there is a bright star in its galaxy, which is rotating around the center of the galaxy at an extremely fast speed. Astronomers speculate that there may be a supermassive black hole in it.
Later, using more accurate and complex calculations, astronomers found that sub black holes did exist.
Its mass is 40 billion times the mass of the sun, and the size of the black hole is so huge that its radius even exceeds the sum of the orbits of all galaxies in the solar system.
According to scientists’ conjecture, this black hole and ton 618 in the constellation of Orion can become the largest known black hole. Research shows that it is formed by the merger of two early galaxies, and this type of Galaxy merger is very rare.
This provides a new idea for scientists to study the formation of supermassive black holes. In about 4 billion years, our galaxy will also collide with Andromeda galaxy, and this collision is likely to produce larger black holes.
In the early 20th century, astronomer Vesto Melvin sliber first discovered the phenomenon of Galaxy redshift, that is, according to the spectral lines, the luminous colors of space objects are different, depending on whether they are close to or far away from us.
The red shift is the far shift, and the purple shift is the near shift.
Based on the discovery of this phenomenon by sliber in 1913, scientists observed that Andromeda galaxy appears purple and is approaching the Milky way at the speed of 120 kilometers per second.
If this theory is correct, the two galaxies will merge into a larger elliptical galaxy in about 7 billion years.
In fact, in this kind of Galaxy collision, the stars and other celestial bodies contained in the galaxy will not really have physical collision contact, because the galaxy itself is very scattered.
For example, the nearest star to the sun, the nearby star, is even 4.2 light-years away.
Theoretically speaking, it is possible for our solar system to be released from the merged Nova system during this collision.
In the early stage of Galaxy collision, it may even become a part of Andromeda galaxy, but due to the distance between stars is very far, this kind of thing will not have any negative impact on the solar system itself.
However, Xiaobian believes that since the sun will enter the red giant stage in 4 billion years, the earth at that time will no longer be suitable for survival.
If human beings can complete the interstellar migration project and continue it, they are likely to witness the collision process of the two galaxies, and this collision has a great chance of forming a larger and record breaking super black hole in the universe.
