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. [2] . Einstein 's theory of general relativity predicts that a sufficiently compact mass can deform spacetime to form a black hole.

In astrofisica, un buco nero è un corpo celeste con un campo gravitazionale così intenso (ovvero, una regione dello spaziotempo con una curvatura talmente alta) che dal suo interno non può uscire nulla, nemmeno la luce [3] essendo la velocità di fuga superiore a c . Il buco nero è il risultato di implosioni di masse sufficientemente elevate.
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 space-time from which nothing, not even light, can escape. According to the general theory of relativity, [3] it starts existing when spacetime gets curved by a huge mass. There is a sphere around the black hole. If something goes inside the sphere, it cannot leave. This sphere is called the event horizon.
8 set 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.
