Matter is different from antimatter

Physicists Discover Dramatic Difference In Behavior Of Matter Versus Antimatter

“We have observed a clear, strong signal for asymmetrical behavior of matter and antimatter resulting from the direct CP violation mechanism,” said James Olsen of Princeton University, one of the leaders of the analysis.

The new observation of a 13 percent preference for the B meson over the anti-B meson dwarfs a similar effect observed in kaons at only a tiny rate of 4 parts in a million. “The effect we have measured with B mesons is roughly 100,000 times stronger than for kaons,” Olsen said. “The pattern of different types of matter-antimatter asymmetries is starting to come together into a coherent picture.”

As I understand it, this has major cosmological implications. CP violation is essential for explaining why there's any matter at all.

The effect we have measured with B mesons is roughly 100,000 times stronger than for kaons

0.13/0.000004 = 32,500

0.13/0.000004 = 32,500

Bah, that's only a factor of 3. The other numbers may have been rounded, as well.

That's right; 2+2=5 for high values of 2.

thanks for the chuckle this morning!
