WebFeb 24, 2024 · The most well-understood black holes are created when a massive star reaches the end of its life and implodes, collapsing in on itself. A black hole takes up zero … WebIn black holes of all sizes, something strange can occur near the inner edge of the accretion disk. A small amount of material heading toward the black hole may suddenly become rerouted into a pair of jets that blast away from it in opposite directions. WebGravity wins out over the internal pressure of the star, because that pressure was produced by a normal, hot gas, and that gas is losing energy as the star radiates energy from the surface. The star may thus end up as a black hole. It just depends upon whether or not the collapse is stopped at some smaller size once another source of pressure ... grad studies university of windsor
