On Tuesday, the clock was set at 89 seconds to midnight — the closest the world has ever been to that marker, according to the Bulletin of the Atomic Scientists, which established the clock in 1947.
The Bulletin of the Atomic Scientists set the clock to 89 seconds before midnight - the theoretical point of annihilation. That is one second closer than it was set last year. The Chicago-based ...
The Doomsday Clock of the Bulletin of the Atomic Scientists, set at 89 seconds to midnight, is displayed before a news conference at the United States Institute of Peace, Tuesday, Jan. 28, 2025 ...
The Doomsday Clock is a symbol that represents the estimated likelihood of a human-made global catastrophe, in the opinion of the members of the Bulletin of the Atomic Scientists. [1] Maintained since 1947, the Clock is a metaphor, not a prediction, for threats to humanity from unchecked scientific and technological advances. That is, the time ...
An atomic clock is a clock that measures time by monitoring the resonant frequency of atoms. It is based on atoms having different energy levels . Electron states in an atom are associated with different energy levels, and in transitions between such states they interact with a very specific frequency of electromagnetic radiation .

The Doomsday clock was set at 89 seconds to midnight on Tuesday morning, putting it the closest the world has ever been to what scientists deem is "global catastrophe." The decades-old ...
International Atomic Time (abbreviated TAI, from its French name temps atomique international [1]) is a high-precision atomic coordinate time standard based on the notional passage of proper time on Earth's geoid. [2] TAI is a weighted average of the time kept by over 450 atomic clocks in over 80 national laboratories worldwide. [3]
