n.
The region, usually described as spherical, marking the outer boundary of a black hole, inside which the gravitational force is strong enough to prevent all matter and radiation from escaping.

event horizon

n
(Astronomy) astronomy the surface around a black hole enclosing the space from which electromagnetic radiation cannot escape due to gravitational attraction. For a non-rotating black hole, the radius is proportional to the mass of the black hole

The solution borrows an idea from string theory that the event horizon contains a three-dimensional hologram (two spatial dimensions and one time dimension) that perfectly depicts the four-dimensional spacetime inside a black hole (SN: 5/31/14, p.
