From a quick glance, baryon number is, so far, found to be conserved.
Rubbish.
The observed Baryon Asymmetry of the Universe (A. Sakharov,1967). tells us that Baryon number is not conserved, not GUT + SUSY.
Like I said, theorised about but not observed.
Recently in another topic I mentioned the "two bishops against two knights" chess endgame problem. I claimed it was investigated over two decades ago by a computer program and established that it is a win situation for the two bishops' side. Then I was unable to Google a solid reference for my claim.
I also remember a "Hermes Set Theory". It was something like ZFC, regarded as a valid Set Theory axiom system for 40 years, until a paradox was found inside. Now, I can't Google it out.
And then it was the so called "Baryon number conservation law", which was postulated for a short while in physics. Until it was found that a subatomic decay may in fact in/decrease the number of baryons in the process. I can't Google that one either.
Is that just me, or what?
