Astronomers have likely discovered the most massive collision of two black holes ever recorded. The chaotic connection of the two objects took place about 7 billion years ago, and now we have received the signal emitted at that time. Thanks to the LIGO and Virgo instruments, researchers were able to observe the birth of one of the most sought-after objects in the universe. Two actors took part in the performance: a black hole with a mass of 66 solar masses and a second black hole with a mass of about 85 solar masses. The two black holes approached each other, orbiting each other at the end at a rate of several times a second, until a collision occurred, during which powerful ripples of space-time were emitted, which spread out across the universe at the speed of light. In the collision, a black hole with a mass of 142 solar masses was formed. This is an extremely important discovery for astronomers. So far, researchers have been able to detect and indirectly observe black holes t...
