    • an excellent void; an abyss: the federal government produced a bureaucratic black-hole that swallows up individual effort.
    • A gravitationally domineering celestial human anatomy with a meeting horizon from where also light cannot escape; the essential thick product into the universe, condensed into a singularity, usually created by a collapsing massive star.

    • An astronomical item whose mass can be so condensed your gravitational force will not allow any such thing, also light, to escape from its exterior limit (the function horizon). The presence of these types of things was first recommended from theoretical considerations. Because light cannot escape from such things, they usually have perhaps not yet been recognized with certainty (1998), but a number of "prospects" being observed whose properties highly claim that they truly are black colored holes. Some theorists declare that the centers of numerous galaxies might have big black colored holes at their cores. See also escape velocity.
    • a spot into which things may enter, but can never ever emerge.
