The NANOGrav consortium of astronomers has discovered the first evidence of the backdrop of long-wavelength gravitational waves, or “ripples” in the fabric of space-time, filling up space. In this respect reported On the website of the U.S. Aeronautics and Space Administration (NASA).
The movement of black holes and other massive objects in space can create ripples in the fabric of the universe, otherwise called gravitational waves. Scientists believe these waves are created by supermassive black holes billions of times the mass of the sun.
Metaphorically, scientists liken detecting the background of gravitational waves to listening to the hum of a large group of people speaking at a party, without distinguishing any particular sounds.
The background detected by NANOGrav could help scientists better understand how gravitational waves are created and what happens to them as they propagate through the universe, according to a NASA statement. they can also
use it to study supermassive black hole mergers that can take millions of years. Experts believe that such mergers occur in most galaxies and have influenced their evolution.
In 2017, he was awarded the Nobel Peace Prize “for his decisive contribution to the LIGO detector and to the discovery of gravitational waves”. considered worthy Representatives of LIGO and VIRGO collaborations are Rainer Weiss, Kip Thorne and Barry Barish.
