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 de sept. de 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.
Un agujero negro es una región finita del espacio descrita en las ecuaciones de Einstein, cuyo interior posee una concentración de masa lo suficientemente elevada como para generar un campo gravitatorio tal que, salvo por un determinado tipo de procesos cuánticos, ninguna partícula ni radiación —ni siquiera la luz — pueden escapar de él [ 1] (...
20 de sept. de 2018 · At the center of our galaxy, a supermassive black hole churns. Learn about the types of black holes, how they form, and how scientists discovered these invisible, yet extraordinary objects...
Learn what black holes are, how they are detected and studied, and what they are not. Find out about the latest discoveries and news on these mysterious cosmic objects.
29 de jun. de 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.
Learn what black holes are, how they form, and how astronomers detect them. Find out about the four types of black holes, from stellar to supermassive, and their effects on space and time.
