Paradox Solved? How Information Can Escape From a Black Hole
Science & Tech  (tags: space, black holes, astrophysics )

Gravity isn't just a pain when you're climbing up a long flight of stairs or careening out of control down a hill on skis - it's also a nuisance for scientists such as Stephen Hawking, who are trying to understand how this force works in the universe.

Giana
- 276 days ago - news.yahoo.com
Physics cannot describe what happens inside a black hole. There, current theories break down, and general relativity collides with quantum mechanics, creating what's called a singularity, or a point at which the equations spit out infinities.
