https://allthatsinteresting.com/black-holeMccoy since you recently have been sending articles and videos in Black holes and neutron stars, I thought I would send this.
First thing’s first. What is a black hole, exactly? In short, it’s a stellar remnant, or what’s left over after the death of a star. A black hole is incredibly dense and its gravity is so strong that nothing can escape it (not even light). However, don’t expect a black hole to form after every star death. If that were the case, the universe would be nothing but black holes.
They only have the potential to form following the collapse of really, really big stars. When these stars die, they go out in style, causing giant supernovas. This also causes their core to implode. Depending on its size, this can create one of two things: a neutron star (the tiniest, densest star in the universe) or a black hole.
