Scientists have failed to confirm that the merging of black holes generates antineutrinos

The general theory of relativity (GR) states that the interaction of any objects with a mass greater than zero

leads to the emergence of gravitational waves.Let us recall that gravitational waves are changes in the gravitational field that propagate like waves. They are emitted by moving masses, but after radiation they break off and exist independently of them. Mathematically related to the perturbation of spacetime metrics and can be described as "spacetime ripples". In other words, these are vibrations of space-time that propagate at the speed of light. For the first time, scientists managed to record them five years ago using the LIGO gravitational observatory. Later, scientists began to use the VIRGO detector.

During the previous cycle, bothObservatory, which began in the spring of 2019 and ended last March, almost all Earth observatories and neutrino detectors were connected to observations of the sources of gravitational waves. The goal is to understand in which galaxies are the sources of space-time oscillations. Also, scientists sought to verify the predictions of general relativity.

Calculations by theoretical physicists show thatBlack hole mergers should almost never leave visible traces. Even bursts of X-rays and gamma rays. And yet, the theory of relativity allows that as a result of such events, powerful beams of neutrinos or antineutrinos can still arise. Theoretically, these particles can be picked up by ground-based detectors.

In a new physics study led byProfessor of Tohoku University (Japan) Kunio Inoue tried to check whether this is so. They compared data collected by LIGO, VIRGO and the KamLAND neutrino observatory.

Data analysis.which was collected between 2016 and 2020, showed that none of the sixty bursts of gravitational waves recorded by LIGO and ViRGO over four years were accompanied by any statistically significant fluctuations in the number of antineutrinos and other low-energy particles.
