According to scientific concepts a black hole starts it's formation after red hot giant stage. During red hot giant state the outer surface of a star rapidly expands and the inner core rapidly contracts which creates a void space between outer surface and inner core. If the mass of inner core is more than 3 times that of our sun the gravity cannot hold the outer surface and it explodes creating a beam of energy formed due to losing of mass to race in the sky. The inner core then left has so much immense gravity that it pulls everything near it. And hence it forms a black hole.
But I think it is false because how can the core pull everything towards itself which could not pull even it's outer surface before. How can anything get so much energy at a matter of time maybe milliseconds so that it can pull anything near it. For example: think you are giving a examination. You cannot write something which you haven't read or heard about before. It is impossible. To make it easy I will give you another example. I cannot lift 100 kilogramme now then how can it be possible that I will lift 500 kilogramme in next few milliseconds.
I think when supernova takes place the spacetime fabric bends so immensely that it will cause near by objects to fall inside it. Even dark matter since dark matter also tries to expand as every other objects on this universe. When dark matter gets in it tries to oppose other matters from getting inside black hole but the slope made in spacetime fabric keeps on pushing the object inside black hole and hence the object starts revolving around the black hole and finally gets in. Now you may think what about dark matter. Let me say you that mass is the only thing that can replace dark matter. Though it cannot replace dark energy but it can replace dark matter. I think this is how black hole works.
If you have any obligations or questions regarding this subject, please feel free to comment. Your question may make me think twice and go towards the path of truth. THANKS FOR READING............
