Gravitational waves continue to be discovered after the collision of two black holes

On September 27, scientists announced the fourth time they had measured gravitational waves after two giant black holes merged at a place in the universe 1.8 billion light-years from Earth.

The gravitational wave was predicted by scientist Albert Eistein in general relativity from a century ago but the evidence of the presence of this type of wave was only discovered by American scientists in 2015.

New gravitational waves of scientists at Virgo Observatory are located in the European Space Observatory (EGO) in Italy and two observatory stations of the Laser Interferometer (LIGO) observatory August 14 after two black holes had masses of 31 and 25 times the mass of the Sun collided at a distance of 1.8 billion light-years from Earth. The two black holes after the collision created a black hole that weighs 53 times the mass of the Sun.

Discovering gravitational waves will help people learn more about black holes.

The Virgo Observatory is located deep underground, operating under the measurement of interference waves, sensing vibrations in space and capturing "super sound" emitted from gravitational waves. Although not as sophisticated and complete as the LIGO gravity observatories located in Louisiana and Washington, Virgo has the capacity to measure gravitational waves. This is also the first time Virgo has caught the signal of gravitational waves only two weeks after it has re-activated after the upgrade.

Gravitational waves are a convincing evidence for Albert Einstein's famous theory of relativity , suggesting that the universe moves continuously, like a giant swimming pool in which planets and stars in the universe move as well. forming waves - is gravitational waves. The discovery of gravitational waves is expected to give humans important applications, and the potential to travel through space and time is feasible. Not only is it applied to physics, gravitational waves also help humans gradually reveal the mysteries in the universe.

For millennia, we observe planets only by light waves . But with the determination of gravitational waves, we can track objects that do not emit light in the universe, typically black holes. Therefore, the discovery of gravitational waves will help people learn more about the black hole, thereby creating a premise for the deep study of the formation of the universe and further research into the possibilities of these another universe.
