How can black holes have no volume and infinte density yet have a finite mass?
In: Physics
Einstein discovered that space itself is bent by the presence of mass within it. You’ve certainly seen the graphic of a bowling ball dropped on a tarp and then a golf ball representing orbit or whatever (if not look it up). A black hole occurs when space is bent so much that it folds in on itself and there are no paths that don’t lead to the singularity and everything, in a run-away reaction of sorts, squeezes down into an infinitesimally small volume.
It’s probably never going to be something you can really visualize or intuitively understand because it is very alien to the human experience. Essentially though it still acts like a mass in space, but it’s weird because space all around it is severely bent, and then if you get too close you realize there is no path through space that doesn’t lead to it’s (so tiny it’s radius is zero) singularity.
