Hosts Joke About Seeing Black Holes
- Josh Clark jokes you can't see black holes because no one has; they're invisible by definition.
- He plays with empiricism to say black holes 'don't exist' to someone relying only on senses.
Black Holes Predicted Before Einstein
- Pierre-Simon Laplace predicted black holes using Newtonian escape velocity long before Einstein.
- If an object's escape velocity exceeds light speed, nothing, including light, can escape it.
Star Life Cycle Creates Black Holes
- Stars balance outward fusion pressure against inward gravity until fuel runs out.
- When fusion stops gravity compresses the core and can create extremely dense remnants.
