Episode notes
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.
Time Slows At The Event Horizon
- The event horizon marks where time effectively stops relative to distant observers.
- Near a black hole time dilates so strongly that at the horizon time appears to stand still.
