I am a big fan of Slashdot's science section, and there are a lot of interesting theories discussed in the articles. Someone suggested that we may already be living in a black hole as well as the existence of a black hole in another black hole's event horizon, it makes sense due to a poster mentioning that the event horizon is relative to an entity's position.
How do we disprove that the universe is not already inside a black hole's event horizon? I remember watching a documentary on string theory and it suggested that the source of gravity was in another dimension and that is why the force has less strength in our universe than in its own dimension; weak nuclear force, etc... are stronger than the graviton. How do we know that the 'dimension' that was spoken about is not a black hole?

A black hole with the wikipedia mass has an event horizon radius of approximately 1.9E+26 meters. Compare with the radius of the observable universe, which is umm.. approximately 1.3E+26 meters. In other worse, if the wikipedia mass is correct, then we are inside a black hole assuming that the Schwarzschild equation for calculating event horizons is correct. I think the existance of dark energy has changed the game tho, such that we certainly cont be confident of the Schwarzschild radius calculation at such large scales.
