Black Hole Shock: Theories revolve around the discovery of a "physically impossible" black hole science | news



A black hole is an extreme region of space-time with gravitational acceleration, so that nothing – even light – can escape. Now the gravitational wave detectors LIGO and Virgo have seen the signal of a frighteningly massive black hole. It is speculated that gravitational wave detection is the result of a cosmic collision involving a black hole of extraordinary size – supposedly as heavy as 100 suns.

However, LIGO Virgo scientists have so far refused to confirm or deny the alleged detection as physically impossible.

Professor Stan Woosley, astrophysicist at the University of California, told Quanta Magazine, "The prediction is not a black hole, not even a few."

"But of course we know that nature often finds a way , "

Hebrew University physicists in Jerusalem discovered in 1

967 that the core of a dying star does not collapse gravitationally into a black hole when it is very heavy forming" evidence for the previous universe "?

The star will instead be exposed to a "paired instability supernova", an explosion that can almost extinguish it right away.

A pair instability Super Nova occurs when the nucleus becomes so hot that light is converted into electron-positron pairs.

The radiation pressure of the light had kept the nucleus of the star intact. When the light changes to matter, the core rapidly shrinks due to the pressure drop and becomes even hotter, which further accelerates the pair production and triggers a domino effect.

Eventually, the core becomes so hot that oxygen ignites and the implosion of the core reverses an explosion.

For nuclei with a mass between 65 and 130 times the sun's size, the star is likely to be totally destroyed.

Cores of between about 50 and 65 solar masses pulsate and shed mass in a series of explosions until they fall below the area where pair instability occurs. That is, there should be no black holes with masses in the 50-to-130 solar mass range.

On the other side of the mass gap, black holes may exist that weigh more than 130 solar masses, since the out-of-control implosion of such heavy star cores can not be stopped, instea d, they continue to collapse and form black holes.

However, because stars are deposited in their total mass life, a star would have to be born that weighs at least 300 suns to end up as a core with 130 solar masses, and those with this size are rare.

For this reason, most experts took the size limit for black holes discovered by LIGO and Virgo would be 50 solar masses, the lower end of the mass gap.

The supermassive black holes with a mass of millions of millions and billions anchoring the centers of galaxies formed by another process in the emerging universe. [19659004] LIGO and Virgo can not detect the collisions of such supermassive black holes.
