How does a supernova or a black hole get created?

Answer 1

I guess in a way, you could say Supernovas do create black holes. But a supernova is a reaction from a star running out of nuclear fuel and the gravitational pull makes the star collapse in on itself. This creates the supernova, which is like an explosion that can outshine an entire galaxy before fading from view over several weeks or months. Supernovas when at it's brightest, can radiate more energy than our sun emits over 10 billion years.

Blackholes are created in the same way, the supernova is practically the explosion of the star. When a supernova has faded, it will leave behind a supernova remnant. But the supernova will create either a blackhole, and if the star was massive, a supermassive black hole, or a white dwarf. Once faded, the white dwarf will become a black dwarf.

Blackholes are a region of space in which the gravitational pull is extremly great. So great not even light can escape its pull, yet the light can never be sucked in. You could say light travels at speed "C" and a blackhole's gravitaional pull is a power of "C", cancelling each other out, the light goes nowhere. Once having being sucked past a point called "Event Horizon" on a blackhole, theres is really no escape. The Blackhole's gravitaional pull is centered at a point called singularity. There is believed a Supermassive Blackhole is at the centre of the Milky Way, the galaxy we live in. No one knows where a blackhole leads to. It could be a rip in space that could transport us to a different universe or just crush us, which its gravitional pull would most likely do as we got closer to singularity.

Answer 2

all supernovas are created by a star. some black holes can be made by stars. some black holes are created by supernovas.
