A shocking news was released today and has to do with our space. Two detectors separated by thousands of kilometers picked up the same signal that corresponds to the most powerful gravitational wave source ever observed.
As reported by El País, the signal was captured on May 21 of last year and lasted barely a tenth of a second. After more than a year of study, the pattern that this characteristic vibration produced in the laser light beams of the LIGO detectors, in the USA, and Virgo, in Italy, has allowed us to reconstruct how this phenomenon occurred.
According to what is explained today, the wave comes from the merger of two black holes and would be the largest captured to date. The collision occurred about 7 billion years ago, before the formation of the solar system and the Earth, when a black hole with a mass 85 times that of our Sun collided with another equivalent to some 66 solar stars.
With the laws of general relativity and what is known about the physics of stars, this phenomenon is impossible to explain: either the theory of stellar evolution must be changed or the black holes involved have an unknown and still mysterious origin.
