AI Comes Up with Bizarre Physics Experiments. But They Work. | Quanta Magazine Artificial intelligence software is designing novel experimental protocols that improve upon the work of human physicists, although the humans are still “doing a lot of baby-sitting.”

LIGO, and bizarre experiments designed by AI [via @quantamagazine.bsky.social] 🧪🔭💡🔬🌌⌚

"[it] used a counterintuitive trick to achieve its goals [,adding] a [] 3-km-long ring between the main interferometer and detector"

The Large Hadron Collider Discovers Mysterious Antimatter Physics The LHCb experiment has observed a new difference between matter and antimatter in particles called baryons

Antimatter behaving badly (who doesn't?) at the LHC [via @sciam.bsky.social] 🧪⚛️🧑‍🔬➰💥

Always exciting when cracks in the Standard Model appear... “charge conjugation–parity symmetry,” more to come!

Is Gravity Just Entropy Rising? Long-Shot Idea Gets Another Look. | Quanta Magazine A new argument explores how the growth of disorder could cause massive objects to move toward one another. Physicists are both interested and skeptical.

Gravity as 'Entropy maximizer' gets another look [via @quantamagazine.bsky.social] 🧪🔭🍎🌍🌌

"the idea that gravity is a collective effect — not a fundamental force, but the outcome of swarm behavior on a finer scale — still compels physicists."

Epic Effort to Ground Physics in Math Opens Up the Secrets of Time | Quanta Magazine By mathematically proving how individual molecules create the complex motion of fluids, three mathematicians have illuminated why time can’t flow in reverse.

Review: The Strangest Man by Graham Farmelo Review: The Strangest Man by Graham FarmeloBritish physicist Paul Dirac had a brilliant mind, but the joys of daily life flummoxed him, discovers Robin McKie

'Why do you dance?' Dirac asked. 'When there are nice girls, it is a pleasure,' Heisenberg replied. Dirac pondered this notion, then blurted out: 'But how do you know beforehand that the girls are nice?' #physicsky www.theguardian.com/books/2009/f...

Supersymmetry Was the Next Big Thing in Particle Physics. What Happened? Supersymmetry, long considered the golden child of theoretical physics, has officially lost its luster at the world’s reigning particle accelerator

SUSY's long fall from grace [via Scientific American] 🧪⚛️💥🌌👨‍🔬👩‍🔬

"Posited super-partners were [] candidates for particles of #dark #matter, and SUSY offered possible routes for a #theory of #quantum #gravity."

*another big ol' rip*

The Big Bang precedes everything, and at that moment *everything* is local. All interactions are causally downstream and are thus also also local. Any perceived locality violation is a failure of framing
