A black hole is a region of spacetime where gravity is so strong that nothing, not even light and other electromagnetic waves, is capable of possessing enough energy to escape it. Einstein's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.
Jun 4, 2024 · Black hole, cosmic body of extremely intense gravity from which nothing, not even light, can escape. It can be formed by the death of a massive star wherein its core gravitationally collapses inward upon itself, compressing to a point of zero volume and infinite density called the singularity.
Sep 8, 2020 · A black hole is an astronomical object with a gravitational pull so strong that nothing, not even light, can escape it. A black hole’s “surface,” called its event horizon, defines the boundary where the velocity needed to escape exceeds the speed of light, which is the speed limit of the cosmos.
Black holes are among the most mysterious cosmic objects, much studied but not fully understood. These objects aren’t really holes. They’re huge concentrations of matter packed into very tiny spaces. A black hole is so dense that gravity just beneath its surface, the event horizon, is strong enough that nothing – not even light – can ...

Sep 23, 2019 · A black hole is an extremely dense object in space from which no light can escape. While black holes are mysterious and exotic, they are also a key consequence of how gravity works: When a lot of mass gets compressed into a small enough space, the resulting object rips the very fabric of space and time, becoming what is called a singularity.
Sep 30, 2022 · A black hole is a region of space packed with so much matter that its own gravity prevents anything from escaping — even a ray of light. Although we can’t see a black hole, the material around it is visible. Material falling into a black hole forms a disk, similar to a whirlpool in a bathtub drain.
Anatomy of a Black Hole Event Horizon This is what makes a black hole black. We can think of the event horizon as the black hole’s surface. Inside this boundary, the velocity needed to escape the black hole exceeds the speed of light, which is as fast as anything can go. So whatever passes into […]
