Einstein’s theory confirmed! Scientists detect low-frequency gravitational waves

After about 15 years of education, An international team of scientists has succeeded in detecting signals from low-frequency gravitational waves for the first time.. Earlier this week, the North American Nanohertz Gravitational Waves Observatory (NANOGrav) had already predicted that it will hold an event this Thursday (29) to unveil the wonderful news in the field of gravitational waves.

According to Chiara Mingarelli, associate scientist at the Center for Computational Astrophysics (CCA) at the Flatiron Institute (United States) and NANOGrav, humanity has been able to detect the ultra-low gravitational wave background for the first time. frequency waves. Therefore, she believes the results open up the possibility of better observing the universe.

The astronomers used data from six radio telescopes, considered the most sensitive in the world, to detect the signals; One of these was the Lovell Telescope at the Jodrell Bank Observatory at the University of Manchester in the United Kingdom. According to the statement, the discovered low-frequency gravitational waves are the strongest of those detected so far.About a million times more powerful than point wave bursts caused by black holes and neutron star mergers.

“The results presented today, The beginning of a new journey across the universe to solve some of its unsolved mysteries. “After decades of work by hundreds of astronomers and physicists around the world, we are incredibly excited to finally see the gravitational wave signature of the distant universe,” said Michael Keith, Professor of the University of Manchester Center for Astrophysics.

low frequency gravitational waves

for Gravitational waves are ripples in space-time produced by catastrophic events in space.like the explosions and collisions of stars and black holes. Physicist Albert Einstein predicted gravitational waves in his most famous publication, The General Theory of Relativity; The first direct detection of waves was made in 2016 by a team from the Laser Interferometer Gravitational-Wave Observatory (LIGO).

Mingarelli also says the discovery is like “a chorus of pairs of supermassive black holes playing at different frequencies.” He explains that NANOGrav only detects the overall gravitational wave background, not the individual frequencies of this black hole “chorus.”

The findings have been published in the scientific journal The Astrophysical Journal Letters, and the team of scientists say the data will help to understand different mysteries of our universe, such as the fate of supermassive black holes or the frequency of galaxy mergers.
