How does a black hole form from a massive star?

Answer 1

Stellar black holes form when the pressure of the massive star is too great.

Over the course of its existence, the massive star fuses hydrogen into helium. When the hydrogen is exhausted, the star continues to fuse elements, such as helium into lithium and so forth, until iron is formed. Because iron is too heavy for the star to fuse, there is a breakdown wherein the core is compressed to an infinitely small point, its density (along with its gravity) increases tremendously, and a black hole is formed, ripping the star apart.

Answer 2

A black hole is formed when the core of a massive star collapses under the force of gravity after running out of nuclear fuel. If the mass of the core is greater than the Tolman–Oppenheimer–Volkoff limit, which is approximately 2-3 solar masses, the collapse will result in a singularity.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
