How are 'black holes' formed?

Answer 1

Black holes are formed when a really big star dies out. When that happens, the outward force of the star's nuclear fusion cannot overcome its gravity, so it collapses. If the star has more than about four times the mass of our sun, nothing can stop the star's collapse, so it becomes smaller and denser until it becomes a singularity. The singularity's gravitational force is so strong that nothing, not even light, can escape it. This is called a black hole.

Whether a star will turn into a white dwarf or a black hole depends on the original mass of the star. The largest stars result the smallest spheres. If is less than 1.4 times the suns mass ,the the gravity among its particles wont be able to overcome the tendency of the electrons, protons,and neutrons to remain separate. the forces will balance when the star has become a white dwarf,a neutron star, or a black hole.

This information comes from a literature worksheet
A star died and blew up creating a gamma ray flare which is so powerful you can see one from across the entire universe I know this because NASA detected one so strong you can see without a telescope and that my friend is where black holes come from. Like the one at the center of our galaxy

Answer 2

Black holes are formed when a really big star, more than eight times the size of the sun dies out. They have an incredible gravity pull, that pulls all matter in it's range towards it Even light can't escape it. however gravity can.
Black holes are most commonly formed by the explosive death of a supernova.
=== === There is a black hole...but idon't know how it is made..so yeah...look it up on Google!!HEHE

Answer 3

Black holes are formed when massive stars exhaust their nuclear fuel and undergo a supernova explosion. If the star's core is sufficiently massive, it collapses under its own gravity, forming a singularity surrounded by an event horizon which defines the "point of no return" for anything crossing it.
