"That means that this is a new kinda black hole, formed by another physical mechanism!"
A stellar black hole, 70 times the mass of our sun?

Black holes of such mass should not even exist in our Galaxy, according to most of the current models of stellar evolution. However, the LB-1 is truly of an unprecedented size ever.
Scientists are now scratching their heads at how LB-1 got so monumental.
Scientists have proposed another theory, although a long shot, but possible.
Another possibility is that it formed from a "fallback supernova". The black hole LB-1 is said to be 15,000 light-years from the Earth.
The more mysterious black holes are the ones found within the center of the galaxies, referred to as "supermassive" black holes. They found that the star was eight times more massive than the sun and orbited a black hole 70 times more massive than the sun.
Space explorations have been radically expanding over time. "This remarkable result ... really points towards a renaissance in our understanding of black-hole astrophysics". During the past year there have been other discoveries that have added to this rebirth.
It should be noticed that our Milky Way galaxy has over 100 million stellar black holes.
The University of Florida professor David Reitze said the discovery "forces us to re-examine our models of how stellar-mass black holes form". In that context, the sheer mass of LB-1 is theoretically very unlikely, until new theories are proved.
Another theory is that the debris ejected from a supernova fell right back into the supernova, and in so doing, created a black hole. If this is how LB-1 was formed, then we could have "direct evidence of this process" for the first time, the study said.
Just as Jifeng stated, theorists are now attempting to explain the black hole's formation and so far, they've posited several ideas.
Black holes themselves are hard to spot, of course, but when objects like stars get to close and are torn apart, telescopes can detect the X-ray emissions as the star feasts.
The researchers on the Chinese language Academy of Sciences tried a assorted capacity. "Intriguingly, the black holes involved in such collisions are also much bigger than what was previously considered typical".
But LAMOST, constructed between 2001 and 2008 in north China's Hebei province, allows researchers to detect up to 4,000 stars simultaneously with each exposure, making it one of the world's most powerful ground-based telescopes.
There had been lots of other discoveries over the past year which occupy added to this renaissance.
