Professor Brian Cox explains the science behind black holes and the beginning of the universe.
Virtually all cosmologists and theoretical physicists endorse the idea that our universe started with the Big Bang. However, problems with dark matter, dark energy, and cosmic expansion have some astronomers rethinking what we know about the early universe.

Our Universe appears to be expanding and cooling, having originated some 13.8 billion years ago in a hot Big Bang. However, it's plausible that what we see from inside our Universe is simply the result of being inside a black hole. This is one of the most fascinating, and yet least discussed, possibilities in modern physics.

Brian Cox and James Beacham discuss the possibility of our whole universe existing inside a black hole.
