If there would really be wormholes, did Einstein or anyone else have an estimate on how we would perceive the time elapsed after passing through one? I understand the definition of a wormhole is the entrance is a black hole, the exit is a white hole, that's what I read once. Means one way journey. Maybe we will be able to generate black holes with a white hole to emit ourselves to another place, but that would still not mean we would escape the end of the universe. Unless I understood wrong and a wormhole is not a black and white hole construct, but leading to another universe.

I dunno maybe someone , preferably Michael Nolan , should make a movie depicting such a concept.

  Upon further research, I have found an academic source, the theory unlike my 2 scenarios, it's a mix, quote: "The complete Schwarzschild geometry consists of a black hole, a white hole, and two Universes connected at their horizons by a wormhole." https://jila.colorado.edu/~ajsh/bh/schww.html https://jila.colorado.edu/~ajsh/bh/schww.html

> I understand the definition of a wormhole is the entrance is a black hole, the exit is a white hole, that's what I read once. Means one way journey. This is not the definition. The source of your confusion might be that the simplest solution to the Einstein field equations that contains a black hole (called Schwarzschild solution[0]), also contains a white hole and a separate, let's say, "universe" when considering its so-called maximally extended[1] solution. The two universes (region I and III in the diagram in [1]) are separated by the black hole and the white hole (region II and IV in the diagram in [1]) and there's only an "infinitesimally small" connection between them, called an Einstein-Rosen bridge[2], which is usually considered to be the simplest example of a (non-traversable) wormhole. People have speculated that on the "other side" of a black hole there's a white hole ejecting the matter swallowed by the black hole into another universe (which would kinda be a wormhole) but this is pure speculation.
