WebBlack Hole. A black hole is a region of spacetime where gravity is so strong that nothing—no particles or even electromagnetic radiation such as light—can escape from it. The theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole. The boundary of the region from which no escape is ... WebFact 3: Black holes have a very high density. You could picture it as trying to fit Earth into a small sphere of about 9 millimeters in diameter.
