This video is a “debate” between a string theorist and two actual physicists (including a Nobel Laureate) over the legitimacy of the multiverse model of reality. It’s really quite embarrassing. The string guy sounds like a penny stock broker trying to hawk his wares by touting the “research” that is just around the corner and right at the edge of proving all the ridiculous tenets of his unprovable or inconsistent or even haphazard concepts.
The other two physicists and the moderator all seem exasperated by repeatedly slapping down both the substance of his argument and the sleight of hand attempts to conflate the standard understanding of quantum mechanics with the string theory basis for the multiverse model. In fact, these physicists provide arguments against both of these things separately and still the string guy keeps on coming up with cutesy analogies for using space-based probes to look for the equivalent of the “ultrasound image of the gestating baby universe in the first microseconds after the Big Bang.” He even manages to talk about the umbilical cord of this fetal universe. It’s beyond silly.
If you’re interested in watching a string theorist getting slapped around this video might be of interest to you. I know I enjoyed it. String theory seems to be the physics equivalent of communism. It’s a theory that has never worked but provides its practitioners with a funhouse version of reality that they can bloviate about and if they manage to get put in charge of resources waste them endlessly until they bankrupt their host.
Highly amusing. I was especially amused to hear that the string guy works at my alma mater. Ah, the pride is back.
