Summary
PKS 2131-021 is a special type of black hole, it is called a blazar. According to a NASA statement, both have been continuously moving towards each other for the last 100 million years and these two supermassive black holes are on the verge of colliding. . Billions of years ago, two black holes collided. At that time the age of our universe was half that of the present time.

Expansion
According to a NASA statement, both have been moving towards each other continuously for the last 100 million years. Now both of them have come in a binary orbit. According to scientists, the two revolve around each other every two years. According to the study published in the ‘Astrophysical Journal Letters’, after 10,000 years, the two black holes will merge with each other. The gravitational waves emanating from their collision can change the cycle of space time.
The great scientist Albert Einstein had already predicted the change in space-time. Black holes, which are called supermassive in scientific language, are extremely deep, dense and millions of times more powerful and bigger than our sun. These are usually found in the middle of all galaxies. However, space scientists do not yet have the exact reason why black holes grow from small to large. But it can be detected based on the study of PKS 2131-021.
charged particle thrown towards the earth
PKS 2131-021 is a special type of black hole called a blazar. There is such a black hole that is throwing a wave of highly charged particles directly towards the earth. The material in this jet is formed from the middle of the hot gas. When this gas comes out into space due to the strong gravitational force, it takes the form of a stream. That is, a thin beam of hot plasma floats in space at the speed of light.
Waves were also felt in the year 2019
In the year 2019, scientists had detected gravitational waves coming from far away in the universe. It was speculated that these waves may have been caused by the merger of two star systems. One of these would have been a black hole 23 times bigger than the Sun and the other 2.6 times bigger.
There was a collision billions of years ago
Billions of years ago, two black holes collided. At that time the age of our universe was half that of the present time. It was detected with the help of gravitational waves. The black hole produced by the union of these two had a mass equal to 150 suns.
