An Israeli scientist has concluded that gamma-ray bursts
from collapsing supermassive stars will "sooner or later"
wipe out nearly all life on Earth, the BBC reported
Thursday. Arnon Dar believes that such bursts of gamma rays
and accompanying energetic particles, while rare, would be
powerful enough to wipe out life even deep in the ocean and
underground. "The few who might survive will wish they had
died," said Dar. "They will struggle, forlornly, on a
wrecked planet."
