Most Precise Clock In The World Created: 100 Million Years Of Running, 'Only Gain Or Lose About A Second'

The most precise clock in the world has been created in the U.S. whose ticking rate varies less than two parts in one quintillion, or 10 times better than any other.

This clock is now the most precise in the world because a pair of atomic clocks made from ytterbium that has just set a new record for precision.

According to newscientist.com, this most precise clock in the world can allow an object that is one centimeter above another might age differently, as prescribed by Einstein's theory of general relativity. It could also set a new standard definition for the second.

"We've reached a new level, an order of magnitude improvement over what had been done before," Andrew Ludlow of the US National Institute of Standards and Technology in Boulder, Colorado, who led the work, told the website.

The staggering preciseness of this clock is something Ludlow noted is hard to believe, but vows how accurate it really is.

"If you were to run this clock for around 100 million years, it would only gain or lose about a second," Ludlow says. These clocks are accurate because we've identified their sources of error and eliminated most of them, so physicists can be confident that its ticking is true.

The "ticks" of atomic clocks are the hyper-regular switching of a group of atoms between two energy levels. The most accurate definition of a second is currently the amount of time it takes for a group of caesium atoms to swing between two states 9,192,631,770 times, according to newscience.com.

This clock has the potential of being more accurate than the caesium clock. It is a more updated version of this clock and overtime is set up to be more precise.
