I don’t really get how somthing that’s small makes it a black hole.
In: Physics
Every atom has a certain amount if gravitational pull, very small but it adds up when atoms are in close proximity.
If all the atoms in an object are densly packed together, then they are all adding their gravitational pull to pull objects into a very small area. Sort of like a focused lens for gravity.
If all the atoms are spread out, then that same gravitational pull is spread out over a larger area, meaning that all the atoms are fighting with each other to pull the object closer to them, some of the forces end up cancelling out.
When things become so immensely packed with atoms they have a gravitational pull so large that not even light can escape. That’s a black hole.
In your example, shrinking something down would make the atoms more dense and focus the gravitational pull until it is able to pull in more atoms to create even more focused gravitational pull.
