Evidence For Antimatter Anomaly Mounts

Posted by samzenpus on 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."

    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.

      All knowledge begins with "Why does X. I don't know, let's find out."

      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"
