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.
8. Sept. 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.
4. Juni 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.
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 ...
30. Sept. 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. Matter swirling around a black ...

20. Sept. 2018 · Learn about the types of black holes, how they form, and how scientists discovered these invisible, yet extraordinary objects in our universe. ...more. At the center of our galaxy, a...
Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can escape the powerful tug of a black hole's gravity. And...
6. Mai 2022 · Black holes are real, they're some of the strangest objects in space. Discover what black holes are and how they form with our informative black hole guide.
12. Mai 2022 · Nature - The Event Horizon Telescope network has captured the second-ever direct image of a black hole — called Sagittarius A* — at the centre of the Milky Way.
