If other universes exist, they predate or parallel to ours. Previous if the universes have collapsed successively on themselves into a Big Crunch before reborn almost instantly from a Big Bang, as a perpetual chain reaction of expansions followed by contractions. Parallels if our universe, like so many others existing at the same time, was the result of the exit of a black hole, without possible return to the original universe, like so many spatial-temporal dead ends aligned with each other. Einstein’s black holes that swallow everything and nothing escapes from Hawking’s quantum radiation that predicts that information can be freed from it. The quantum computer was trying to finally separate the two geniuses.
