Hint: A star is made up of a large number of heavy hydrogen atoms. Hydrogen atoms fuse into helium at their centre, producing a significant amount of energy. The released energy, in the form of radiation, pushes against gravity, keeping the two forces in a delicate equilibrium.
Complete answer:
As long as there is fusion in the core, a star is stable enough. The heat and pressure at the core of stars considerably more massive than the Sun allow them to fuse into heavier elements until they create iron. Iron accumulates in the core until it reaches a critical threshold, at which time the equilibrium between radiation and gravity is disrupted. The core collapses and implodes into itself as a result of this. It feeds even more mass into the core as it travels at approximately a fourth of the speed of light. All of the Universe's heavier elements are created at this precise time. Depending on the mass of the star, it turns into a black hole when it dies in a supernova explosion.
It was only recently discovered that black holes exist. Of course, whatever we know about them is based on our observations of them. We can see the closest black hole to us in the core of the Milky Way Galaxy, but there is too much matter between us and it for us to see it.
Everything we know about black holes is based on theoretical considerations. A black hole is a mystery because it defies physics' principles. That is, after you cross beyond the event horizon, space and time begin to warp until disappearing entirely where a "singularity" exists. It is uncertain what happens to matter when it approaches the singularity.
Some scientists believe that the "bottom" of a black hole is a portal to another dimension, while others believe it is a portal to another universe, but no one knows for sure, and no one will ever know because we can't get near enough to sort these things out.
Note:
That black hole is said to be a gigantic garbage. The majority of what gets in is destroyed. They defy our fundamental knowledge and physics rules. As far as we know, there is nothing on the other side. As previously said, everything is hypothetical; we have no clue what a black hole does other than have a huge gravitational pull and cause our galaxies to spiral.
