the location, frequently described as spherical, establishing the exterior boundary of a black opening, inside that your gravitational power is powerful enough to avoid matter or radiation from escaping.
The gravitational world of a black hole within that the escape velocity is higher than the speed of light, causing time to virtually stop.
A point of no return, by analogy towards the astronomical consumption
the boundary surface surrounding a black opening, from outside which absolutely nothing inside may be observed, because nothing inside that surface, even light, can escape beyond it. See additionally black-hole and escape velocity.
the location, usually referred to as spherical, marking the exterior boundary of a black opening, inside that your gravitational force is strong enough to avoid matter or radiation from escaping.
The gravitational sphere of a black gap within that your escape velocity is greater than the rate of light, causing time for you practically stop.
a spot of no return, by analogy towards astronomical consumption
the boundary area surrounding a black opening, from away from which absolutely nothing inside could be observed, because absolutely nothing inside that area, also light, can escape beyond it. See in addition black hole and escape velocity.
