Matter's Place in Supernovas and etc.
How a Supernova Happens
A supernova happens extremely rarely. This is because it's only when two stars collide; which only occurs when said stars come into range and the star with the larger mass or greater density sucks in the one with the lesser mass and density. When this happens, their chemical compositions create a collision that results in a massive explosion.
Another way a supernova can happen is if a star runs out of hydrogen and helium fuel. Needless to say, when a star runs out of fuel in its core, it dies. When a star dies, a supernova occurs.
Like the sun, it eventually runs out of hydrogen from its core (where the stars collided) but it does have enough mass and pressure to fuse/produce carbon. Also, much much time after the supernova happens, there's a good chance it can create a black hole. The mass of the supernova can change the size of the black hole.
Black holes, on the other hand, can also be made when a massive star at least 20 times bigger than our sun runs out of fuel. The size of the star can either make a supernova, a black hole, or both. A single-stellar black hole can grow exponentially, consuming stars and planets alike. Stars can collide during this and create even more supernovas/black holes.
