1The Doomsday Clock
The Doomsday Clock is a theoretical clock maintained by the Bulletin of the Atomic Scientists since 1947 and the dawn of the Cold War. It represents how close we are to Nuclear Armageddon, with 12:00 am being “Doomsday.” The closest the Clock got to midnight was 11:58 pm in 1953 - the farthest was 11:37 in 1991. It currently stands at 11:55 and that is one alarm we don't want to go off!
