The discovery of glueballs would provide direct evidence that gluons can interact with themselves, researchers say. This is a key prediction of quantum chromodynamics

This led me on a 1.5 hours long, entertaining chat session with Gemini learning about stuff in Physics - hopefully without much hallucinations. But definitely with a lot of typical - "You have arrived at a great insight.." like egging on by the AI :D

But learned a bunch about bosons, fermions, QCD, gluons, Kugelblitz, composite bosons and finally Noether’s Theorem on symmetry. Was a wild ride

Isn't it significant in some sense that this was discovered in China first, and not the US?

In the sense of: we didn't know splitting the atom would change warfare forever, back when Einstein and others published on it. We don't know if there are discoveries of similar impact lying in wait somewhere. If China gets to such a discovery first, we are in Sputnik territory, to say the least.

Interesting how should someone uses it IRL at the end of the day

are we going to have force-fields now?

Oh no. A new particle. Who would have guessed %]

And here I am, thinking I discovered "glueballs" in elementary school when we were given rubber cement to use.
