. . . and by humans, not God. Today’s New York Times reports that a physics experiment conducted at Brookhaven National Laboratory, and involving the collision of nuclei to create states mimicking those present in the early universe, has succeeded in creating local conditions that violate the laws of physics. The law, in this case, was parity: the principle that other physical laws, and the behavior of particles, are independent of a distinction between left and right. Apparently a violation of parity was seen in the quarks produced by those nuclear collisions, quarks that behaved asymmetrically. (Those collisions also created a temperature of 4 trillion degrees Centigrade!).
I’m not a physicist and can’t vouch for the importance of this result, but I suspect that Sean Carroll will soon be explaining it over at Cosmic Variance.
Update: Sean Carroll did his homework and put up a post on this. In the end, the result doesn’t seem nearly as earth-shaking as the Times made out, but is that a surprise?
