(Before It's News)

They say ‘A flat ocean is an ocean of trouble. And an ocean of waves… can also be trouble.’ So, it’s like, that balance. You know, it’s that great Oriental way of thinking, you know, they think they’ve tricked you, and then, they have.” –Nigel Tufnel

When you travel towards an object like a moon, planet or star, the closer you get, the larger it appears. Halve the distance and its angular size doubles; reduce the distance to a quarter and it appears four times as large. But for black holes, their gravitation is so strong that relation no longer holds as you approach the event horizon.

Instead, the region of “blackness” increases much faster than you’d expect, eventually taking over a full half of the sky as you crossed the event horizon and causing all the light-paths to contract down to a point behind you the instant before you hit the singularity. Even less intuitive is what happens to the gravitational field, which would show the singularity in all directions once you crossed over the event horizon.
