The most confusing part of space has been the biggest black holes in the universe. Scientists have been wondering how black holes have formed for years. There has been new evidence recently that says they could have been started “inside giant cocoon-like stars”. This is completely different then the theory that large black holes are “created by the clumping together of smaller black holes.”
The galaxy scientists are looking at is NGC-1097 that has a huge black hold that is surrounded by stars in its center. University of Colorado scientists think that the biggest black holes have been created by huge stars that were formed soon after the Big Bang.
But astrophysicist, Mitchell Begelman, of the University of Colorado at Boulder, thinks they have been formed “in the middle of even larger supermassive stars that could have held tens of millions times the mass of our sun.” He says “until recently, the thinking by many has been that supermassive black holes got their start from the merging of numerous, small black holes in the universe, this new model of black hole development indicates a possible alternate route to their formation.”
Begelman has been studying how the stars have formed and how they could have given a rise to huge black holes. The stars could have been formed a few hundred million years after the Big Bang. Begelman feels the “cores of the giant stars had burned all their hydrogen, they would have collapsed, forming dense black holes.”
The gas from the stars would have remind but over time the black holes would “have swallowed all remaining stellar matter within their reach, ballooning rapidly to staggering weights. Begelman thonks that it is possible that both methods could have happened.
I tought this was really interesting because black holes are seen as a mystery to what happens after things get sucked up into them. Maybe if finding a new way they were formed can help us figure out what really happens.
