... Given that protons have a lifetime of at least 1031 years, this ratio has had the same value for much of the history of the universe; that is: [baryon number density] ~ R -3 [photon number density ] ~ T 3 ~ R -3, so the ratio is independent of the length scale factor R. What about today's anti-baryo ...

With that foundational framework established, I then present the simple argument from quantum principles for the natural tendency of neutrinos to oscillate. ...

Compact Muon Solenoid

The Compact Muon Solenoid (CMS) experiment is one of two large general-purpose particle physics detectors built on the Large Hadron Collider (LHC) at CERN in Switzerland and France. The goal of CMS experiment is to investigate a wide range of physics, including the search for the Higgs boson, extra dimensions, and particles that could make up dark matter.CMS is 21.6 metres long, 15 metres in diameter, and weighs about 14,000 tonnes. Approximately 3,800 people, representing 199 scientific institutes and 43 countries, form the CMS collaboration who built and now operate the detector. It is located in an underground cavern at Cessy in France, just across the border from Geneva. In July 2012, along with ATLAS, CMS tentatively discovered the Higgs Boson.
