Physics Professor Gerald Gabrielse??s trip to north of the Arctic Circle in Finland to give the opening talk of a conference placed him “right in the path of the unexpected volcanic dust from Iceland,” he wrote in an e-mail to his quantum mechanics class...
...Posner’s credit, Catastrophe does anticipate Gabrielse??s counter-argument. Posner writes that “a cosmic ray hitting a fixed target such as the moon will tend to scatter the nuclei that it hits, making it less likely that they will clump”—and thus produce strange matter—“than if the collision were head on,” as it would be inside RHIC. So, the fact that the moon has existed for 4.5 billion years without condensing into a tiny ball does not necessarily...

Chair of the Department of Physics John Huth called Gabrielse??s work a “tour de force.” “It would be a rather tremendous discovery if he found that there were distinct differences between the properties of hydrogen and antihydrogen,” he adds...
...addition, Gabrielse??s team was able to measure the distance between the positron and antiproton in an antihydrogen atom by the magnitude of the voltage required to pull the two particles apart, enabling them to better map the internal structure of the atom...
