I aspire to understand all of this some day. The best part: “The negative square root solution outisde the horizon represents another Universe….The inhabitants [of the two Universes] can meet… and soon meet with regularity.”
White Holes and Wormholes
By Andrew Hamilton, 2001
The complete Schwarzschild geometry consists of a black hole, a white hole, and two Universes connected at their horizons by a wormhole.
The negative square root solution inside the horizon represents a white hole. A white hole is a black hole running backwards in time. Just as black holes swallow things irretrievably, so also do white holes spit them out.
