Particle physics is stuck
In reality particle physics is nowhere: 80 years of nonsensical claims have passed and the culmination was a fake claim that assigned the 4 rotation proton to the Higgs particle...
The culmination of the above nonsense video is the claim that new particles live in the phase space...The phase space is accessed over symmetries and per definition something you find as being a symmetry is nothing new just a projection of something known.
But even such simple things did never work out in the standard model as so called projected particles just follow the most simple logic e.g. spin,charge or some fake features called charm or color. But these projections always have unknown rules for predicting their mass or related the live time etc..
So SM is crap and will end (as a potential contamination...) on the dungheap of history.
