Have you heard of a supernova?  If you haven’t, it’s what happens when large stars (larger than our sun) fuse atoms together to make iron, which doesn’t create energy, ending the star’s life, and the gravity of the star crushes it and then makes it explode outward.  But what happens when you have a much, much, MUCH bigger star?  Just watch this:

Now are stars that big common?  No.  You might hear about those types of stars more since they’re pretty interesting to humans, but they aren’t that common.  But you might be wondering: what happens when a star goes supernova instead of hypernova?  Well, it doesn’t create a smaller black hole.  Instead, the core becomes something called a neutron star.  ——–> A neutron star has a ton of gravity, just like a black hole, but not nearly as much.
