How they know this is beyond me, but according to U.S. physicists they’ve crafted a clock that will neither gain nor lose a second in the next 200 million years. The unnamed clock even out performs the U.S Commerce Department’s National Institute of Standards and Technology clock, which promises to keep time accurate to the second for 80 million years. So what are these clocks used for? Deep space navigation where a slight error could disrupt and destroy a mission. Other uses include synchronizing telecommunication networks ‘that some day lead to things like hands-free driving in satellite-guided cars.’ If you ask me, it all sounds like a bunch of smoke, but I’m not a scientist.
