China claims to have captured ‘legendary’ space signal

The FAST telescope located in Guizhou – China has found the first evidence of some kind of cosmic signal that can help humanity reach supermassive objects “through the air” in the early universe.

Online publication in an international scientific journal Research in astronomy and astrophysicsChinese scientists say that by observing pulsars, they found Important evidence for the existence of nanohertz gravitational waves..

The nanohertz gravitational ball is theoretically known, but its direct capture is difficult. It has extremely low frequencies, wavelengths up to several light years.

ƑAST is one of the most powerful radio telescopes in the world, capable of observing long-term objects “difficult” like millisecond pulsars, one type of neutron star – massive star corpses – is extremely active, with a rotation period of only 1 to 10 milliseconds.

Theo CGTN, Taking advantage of FAST’s high sensitivity, researchers led by the National Astronomical Observatory of China, Chinese Academy of Sciences (ƝAOC) under the China Pulsar Time Array (CPTA) project tracked 57-millisecond pulsars with a steady beat for 41 months.

This tracking inadvertently revealed signs consistent with the “legendary” signal known as nanohertz gravitational waves, with a false alarm probability of just 2 parts per million.

“Nanohertz gravitational waves open an important window for human observation of the universe, which will certainly lead to many major discoveries in physics” – ƝAOC manager Chang Jin confirmed.

Chang Jin said the discovery will be applied to studying supermassive objects in the universe, including black holes. “freak”the formation – evolution – fusion of galaxies, the structure of the primordial universe…
