singularity
Quick Summary
A singularity, in astronomy, is a point of zero volume and infinite density. It is thought to be the incredibly dense center of a black hole, formed when a massive star collapses inward after a supernova. This extreme density warps space-time, causing time to slow down dramatically near the black hole's event horizon.
The concept of a singularity is also central to the big bang theory, which posits that the universe began as a singularity—an extremely hot, dense point containing all of space, time, and energy. This singularity then underwent a vast expansion, not an explosion, to form the universe we know today. The exact origins of this initial singularity remain a mystery.

Penrose also developed a method of mapping the regions of space-time surrounding a black hole. (Space-time is a four-dimensional continuum comprising three dimensions of space and one of time.)…

…in a vanishingly small volume—a singularity—gravity will become so strong that nothing pulled into the surrounding region can ever leave. Even light cannot escape. In the rubber sheet analogy, it as if a tiny massive object creates a depression so steep that nothing can escape it. In recognition that this…
