Evidence For Antimatter Anomaly Mounts

Posted by samzenpus on Wednesday February 29, 2012 @08:00AM from the nature-of-things dept.

sciencehabit writes "The big bang created a lot of matter—along with the same amount of antimatter, which wiped out everything and brought the universe to an untimely end. That's what accepted theoretical physics tell us—though things clearly didn't work out that way. Now, results from a U.S. particle smasher are providing new evidence for a subtle difference in the properties of matter and antimatter that may explain how the early universe survived."

So then, its like populating the roads with an equal number of Priuses and Lincoln Navigators?

  Yes. The Navigators, being made by Lincoln would decay at a faster rate than the Priuses made by Toyota.
  Therefore eventually there would be more Priuses on the road than Navigators.

Lol so the very fact that there is a universe, in which we can contemplate the laws of physics, is itself a phenomenon that the standard models can't yet explain? Nice. Seems like a minor hole :)

  And at one point we couldn't even model two point particles interacting in a collission. Just because we don't know how it works today doesn't mean we never will.

  The standard model also doesn't explain dark matter, gravity, quantum physics and pile of other things. However, it does explain a lot of things really well, so until we can come up with the Grand Unified Theory of Everything, we're stuck with what we got.
  It's like how Newton's equations of motion work extremely well for general everyday human-scale physics, but fail when you go really small or really fast.
  Lots of things we understand in physics have limitations, and as long as we observe them, they do hold up.

  Hell .. I don't even think there is an understanding as to what gravity is. And thats a lot less existential than "existence/non-existence"

Summary goes a bit too far... by Anonymous Coward · 2012-02-29 08:49 · Score: 5, Informative

The research is certainly interesting and important (at least to physicists), but it demonstrates CP violation only in certain relatively rare particles, the neutral D mesons. CP violation has been known to exist for a while (in K and B mesons), so that really is not that ground breaking. On the other hand, as far as I know, these effects are far too small to account for the matter/antimatter imbalance in the universe and additional mechanisms are required.
