An event horizon is an extremely powerful energy field. This field surrounds certain astronomical phenomena, such as black holes, singularities and wormholes.
At the event horizon, the escape velocity equals the speed of light, making escape from the gravity well impossible under normal circumstances.
In general relativity, an event horizon is the part of a black hole where light cannot escape. To any object in the event horizon, time slows down upon approach and comes to a standstill as the object reaches the center of the event horizon.
The idea of a "breach" in an event horizon is impossible, as an event horizon is a mathematically defined distance from the center of a massive object rather than a physical object.
