- Abstract:
A recent article in New Scientist discusses the development of the most accurate clock in the world, which can maintain its accuracy for 40 billion years. The clock, created by Alexander Aeppli and his team at the University of Colorado Boulder, is based on the oscillations of strontium atoms cooled to near absolute zero. The clock's accuracy is eight parts in a tenth of a billionth of a billionth, or less than 1 second in 40 billion years. While the clock may not immediately lead to new discoveries, it sets a standard for atomic clocks and has potential applications in detecting dark matter, improving GPS precision, and studying tectonic plate movements.
