The quarks, antiquarks, and gluons of the Standard Model have a color charge, in addition to all the other properties like mass and electric charge. All of these particles, except gluons and photons, experience the weak interaction. Only the gluons and photons are massless; everyone else, even the neutrinos, have a non-zero rest mass. (Credit: E.

When the Large Hadron Collider at CERN turned on in 2008, all of particle physics was wondering just what it would discover, and how long it would take to find the new things it was seeking.
In 2012, the CMS and ATLAS collaborations jointly announced the discovery of the Higgs boson: the last undiscovered fundamental particle in the Standard Model, with a mass of ~125 GeV.
But finding the Higgs and measuring its properties hasn’t completed the story of how particles came to exist in our Universe. The baryogenesis mystery remains, and the Higgs may be the key to unlocking it.
In some ways, the deepest question one can ask about our physical reality is simply, “What is the Universe made of?” In the early 1800s, we thought we knew the answer: atoms. By the early 1900s, the answer had grown much richer: atoms themselves were composed of atomic nuclei and electrons, which were capable of both emitting and absorbing photons: particles of light. However, it was the 1932 discovery of the neutron — along with the…

Can any of you fix my flux capacitor, I’m late for a future appointment. ( Sorry mate , I noticed there were no crackpot comments yet and thought you might be missing Peter )🤣
I find it humbling that even after such major discoveries, nature can still leave us with deeper questions. It reminds me that curiosity matters as much as having answers, because every breakthrough can open another mystery⭐⭐⭐
The Higgs Boson is the source of the force of gravity, G and is at the center of the proton. The three quarks are in an upside down triangle, two up, one down, defining the charge shell diameter. The unbound photon and the valence electron are…
