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]

The development of atomic clocks has led to many scientific and technological advances such as precise global and regional navigation satellite systems, and applications in the Internet, which depend critically on frequency and time standards. Atomic clocks are installed at sites of time signal radio transmitters. [103]
International Atomic Time (TAI) [12] is the primary physically realized time standard. TAI is produced by the International Bureau of Weights and Measures (BIPM), and is based on the combined input of many atomic clocks around the world, [13] each corrected for environmental and relativistic effects (both gravitational and because of speed ...
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 ...
Humanity is closer to destroying itself, according to atomic scientists who revealed on Tuesday that the famous “Doomsday Clock” was set to 89 seconds to midnight — the closest it has ever been.
One marvel of the 21st century is that anyone with an internet connection and device newer than the year 2000 can at any point pull up satellite imagery of the entire world. Even more, if the area ...
