Neither schwarzschild nor einstein believed this object was anything other than a mathematical curiosity it took a much better understanding of the lives of stars before black holes were taken. It not only explains the motion of the planets it can also describe the history and expansion of the universe, the physics of black holes and the bending of light from distant stars and galaxies.

Star formation in the early universe may have resulted in very massive stars, which upon their collapse would have produced black holes of up to 10 3 m ☉ these black holes could be the seeds of the supermassive black holes found in the centers of most galaxies [105.
Black holes are the strangest objects in the universe a black hole does not have a surface, like a planet or star instead, it is a region of space where matter has collapsed in on itself this catastrophic collapse results in a huge amount of mass being concentrated in an incredibly small area.
