Physicists imagine a day when they will be able to design a clock that’s so precise, it will be used to detect subtle disturbances in space-time
or to find the elusive dark matter that tugs on everything yet emits no light. The ticking of this clock will be almost perfect.
That dream may not be far off: A group of researchers has created a clock that, with some tweaks, could be four to five times more precise than the world’s best clocks. To put that into perspective, if today’s most precise clocks…
