The stuff that comes out of Harvard these days and get published in Scientific American used to be tabloid news. What has changed?
As in the Schwinger effect, it is conceivable that a violent irritation of the vacuum potentially could create a baby universe. Whether that’s possible depends on subtle details and is a subject of active research, which I studied recently as the time reversal of a collapse to a black hole, with Paul Chesler, a postdoctoral fellow at Harvard’s Black Hole Initiative.
An artificial birth channel could have interesting implications for our own cosmic origins. If our universe was created in the laboratory of another civilization, one could imagine an infinite sequence of baby universes born out of each other by civilizations that developed the technological womb capable of giving birth to new universes. In this case, the umbilical cord of our big bang has its origin in a laboratory. Avi Loeb, “Endless Creation Out of Nothing” at Scientific American (December 12, 2020)
