Doomsday Clock Moved Closer

401642 05: Using a slow camera exposure to simulate clock movement, the hands of the Bulletin of the Atomic Scientists "Doomsday Clock" are seen at 11:53 p.m, two minutes closer to midnight, displayed February 27, 2002 at the University of Chicago. The hands of the Doomsday Clock, for 55 years a symbol of nuclear danger, were moved two minutes closer to midnight February 27 reflecting the possibility of terrorism, relations between India and Pakistan, and other threats. The symbolic clock, kept by the Bulletin of the Atomic Scientists, had been set at 11:51 since 1998. (Photo by Tim Boyle/Getty Images)
