Difference between Black hole and Outline of physics

Black hole vs. Outline of physics

A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it. The following outline is provided as an overview of and topical guide to physics: Physics – natural science that involves the study of matterRichard Feynman begins his ''Lectures'' with the atomic hypothesis, as his most compact statement of all scientific knowledge: "If, in some cataclysm, all of scientific knowledge were to be destroyed, and only one sentence passed on to the next generations..., what statement would contain the most information in the fewest words? I believe it is...
