The latest wave of gravitational waves says Black holes can absorb neutron stars – BBC News, BBC Thailand

A team of scientists from the LIGO gravitational observation device in the United States and VIRGO in Italy reported finding gravitational wave signals. The latest wave of gravitational waves on April 24th The signal may indicate that a black hole event absorbs neutron stars in deep space

Detect this event Considered as the first time that astrophysicists can confirm that black holes and neutron stars with huge mass and high density can live together in a binary system and meet

Astrophysicists believe that the black hole event absorbs the neutron star. Occurs about 1,200 million light-years away from Earth and is expected to release both light waves.

Professor Patrick Brady, spokesman for Lyoko, said that Still need to prove again that such gravitational wave signals come from the system of black holes – real neutron stars. No signal of other interference waves

"It's like we're trying to listen to a person's whisper." At the coffee shop, there's a lot of enthusiastic discussion – the risk that this gravitational wave will become a mistake is about 14%, "said Professor Brady.

Proof that this method uses light waves that occur in the same event that, if it exists, can be seen by telescopes on the Earth This radiation can also indicate the size of the black hole and the characteristics of the light. absorption of the neutron star. Large black holes are less dense and have less gravity on the outer edges. Cause the neutron star not to collapse at risk before being absorbed What in the case of a small black hole is the opposite

Recently The Lago-Verko gravitational wave observing device that offers superior efficiency Can detect gravitational waves from deep space often Whose this wave is a space-time ripple (space-time) that radiates from 39, a violent collision of a huge space object Last April, it was able to detect up to 6 times, including the gravitational waves of colliding neutron stars. Which was detected for the second time last April 25

The neutron star is caused by the collapse of a large nucleus of stars after the explosion of the supernova. There is a high density due to the compression of the huge mass that equates to 2 or 3 suns gathered in an area equivalent to a small town of 20 kilometers in diameter. The outer surface of the star is always composed of all the neutron particles. Which is stronger than tens of millions of steels
