世界末日?

At the recent AAAS meeting, Stony Brook University’s Robert Crease talked about a doomsday scare involving Scientific American and Brookhaven National Lab’s Relativistic Heavy Ion Collider, or RHIC:

“As the accelerator neared completion in 1999, Scientific American ran an article about RHIC, called ‘A Little Big Bang,’ with the title referring to the machine’s ambition to study forms of matter in the early universe.”

A reader wrote in wondering if black holes might be created. Sci Am printed the letter with a considered response from physicist Frank Wilczek.

“Wilzcek said that the black hole scenario was incredible. But he also said that there’s a more likely possibility that it might create strangelets, which would swallow ordinary matter and described that as [merely] not plausible. That then prompted a series of headlines including this from the Sunday Times of London, entitled ‘Big Bang Machine Could Destroy Earth’.”

Scientific American, Brookhaven and the Earth survived. Wilczek won the Nobel Prize in 2004 for his earlier work.
