How atomic time-travel could reveal the mysteries of dark matter and more

Physicists from the University of Colorado have created an atomic clock so precise it can measure gravitational time dilation over distances as small as one millimeter. This record-breaking measurement could have implications reaching as far as redefining exactly how long a second is or discovering where all the dark matter in our universe is hiding. Up front: Einstein figured out that time functions differently depending on how close to a “gravity well” the observer is. So, for instance, if you’re standing on the Earth wearing a watch it’ll run a tad bit slower than if you’re out in space. This…
