Crisis in Particle Physics Forces a Rethink of What Is ‘Natural’ | Quanta Magazine
For three decades, researchers hunted in vain for new elementary particles that would have explained why nature looks the way it does. As physicists confront that failure, they’re reexamining a…
“Taken together, the new UV-IR mixing models illustrate the myopia of the old paradigm — one based solely on reductionism and effective field theory — and that may be a start.
“Just the fact that you lose reductionism when you go to the Planck scale, so that gravity is anti-reductionist,” Dubovsky said, “I think it would be, in some sense, unfortunate if this fact doesn’t have deep implications for things which we observe.””Posted on 2022-03-02T08:00:23+0000
