Graduate Student's Reagents-The most accurate atomic clock developed by American physicists in 5 billion years is not less than one second

American physicists have developed the most accurate atomic clock to date, and will not deviate by 1 second for 5 billion years.

This "Strontium Lattice Clock" was developed by the United States Astrophysics Joint Laboratory (JILA) co-founded by the National Institute of Standards and Technology (NIST) and the University of Colorado. 50%.

The researchers wrote in a report published in the journal Nature that they placed thousands of strontium atoms in a very stable red laser. The precise frequency of the laser induced the strontium atoms to oscillate between the two energy levels. Researchers have discovered that strontium lattice clocks can "walk" 430 trillion "ticks" per second.

The British "Daily Mail" quoted researchers on the 22nd and reported that they plan to further improve the accuracy of atomic clocks, "you can expect our clock to achieve more breakthroughs in the next 5 to 10 years."
