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.
Hace 1 día · 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 ...
A black hole is a region of spacetime where gravity is so strong that nothing, including 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.
The Black Hole (en Argentina, en España y en México, El abismo negro; en Venezuela, El agujero negro) es una película estadounidense de 1979 del género de ciencia ficción.

Black holes grow by consuming matter, a process scientists call accretion, and by merging with other black holes. A stellar-mass black hole paired with a star may pull gas from it, and a supermassive black hole does the same from stars that stray too close.
