- Two black holes collided in space
- The collision resulted in The biggest explosion humans will ever see He can
- The The gravitational wave can still be felt on Earth It can be measured
Scientists continue to discover new black holes moving across the galaxy. Its mass is so dense and compact and it generates such strong attraction that it eats up all the matter in its environment. So far, however, little is known about the phenomenon of voracious space. Researchers have now succeeded in observing a previously unprecedented process: Collision of two black holes.
Black holes collide: Scientists are observing their collision
The collision occurred about seven billion light years from Earth. The two black holes merged and created a new black hole. The result of the collision was the presence of a new black hole GW190521, about 142 times the size of the sun. In the process, masses of energy were released that they disrupted the universe. “It is the largest explosion since the Big Bang – the largest explosion humanity has ever seen,” says the study report in the Journal of Science Material Review Journals.
The massive release of energy on Earth can also be felt. As the scientists explained in their study, at the moment of collision, the continuity of space-time expanded, collapsed and vibrated. This created gravitational waves that were also measurable on Earth on May 21, 2019. The signal lasted only a tenth of a second.
Also interesting: Just last year, researchers discovered a massive black hole that eats up the Sun’s mass every day and is growing at a record pace.
A new genus of black holes: GW190521, the first celestial body of its kind
It’s also possible that the size of a newly created black hole is remarkable. Until now, science has divided celestial bodies into two categories: black holes ten times the mass of the sun and black holes between 100,000 and several billion times the size of the sun.
With GW190521, astronomers have seen the birth of a new genus of black holes: “medium mass” black holes. Some potential celestial bodies of this type have already been discovered, but the formation of GW190521 is now the first direct evidence of their existence.
