Will Black Holes Really End in Singularities… Or Something Even Stranger?

Will Black Holes Really End in Singularities… Or Something Even Stranger?

General relativity predicts that everything falling into a black hole crushes to a single point of infinite density. But that prediction is also where the theory stops working, spitting out infinities instead of answers. This video traces the century-long argument over whether that point is real, from Einstein rejecting the idea to Penrose proving singularities are unavoidable under classical physics, and then to the quantum gravity frameworks — Planck stars, fuzzballs, firewalls, holography — built to replace the collapse with something finite.
