In the Universe for the first time found a gravitational and wave background

Scientists of North American nanohertz observatory of gravitational waves of NANOGrav for the first time found a background of the gravitational waves which have arisen because of facing supermassive black holes in the Universe. About it it is reported in article published in the The Astrophysical Journal Letters magazine. Researchers, watching frequency of pulsars, revealed huge waves of space time which make a background of gravitational waves. They bear approximately a million times more energy, than the waves revealed by LIGO and Virgo, and are ultralow-frequency as on lifting and recession of one wave can leave...
