are trying to sign up 600,000,000 people in the Western hemisphere to jump simultaneously on July 20, 2006, at 7:39:13 PM (Pacific time -- you can find your local time on their website).
Why? Well, according to German researcher Hans Niesward and his colleagues at the Department of Gravitationsphysik at ISA/München, if 600 million people jump all at once, the earth could be bumped into a slightly new orbit. The result: Longer daytime hours, a more habitable average global temperature (particularly helpful to developing countries around the equator), and no more global warming!
Dave labels this effort "...hopeful and slightly melancholy..." I'll definitely be jumping, though -- what the hell!
