The supermassive blackholes at the center of galaxies.

If you want to learn about black holes, I suggest you either read the Wikipedia article with the title "black hole", or you search for YouTube videos on "black holes".
There are two ways blackholes form:Massive blackholes - these are formed by collapse of stars having more than 3 times the mass of our sun, when the stars die.Micro blackholes - these could have only formed in the big bang. Their event horizons are roughly the size of a proton and their mass is similar to that of a mountain. Unlike massive blackholes, which last forever, these evaporate then explode giving them a limited lifetime.
Sufficiently large gravitational bodies... blackholes are the most common.
When you get close to a black hole, it will stretch you to where all your insides get crushed.
