How close are we to doomsday – the destruction of the planet and the end of life as we know it? The Doomsday Clock is a symbolic way to answer this question. In 1947, a group of scientists who had worked on the world’s first atomic bomb started tracking how close the world is to doomsday. They marked the end of the world at midnight on their metaphorical Doomsday Clock. The clock is adjusted yearly according to political instability and environmental dangers that threaten the safety of the world.
