Relativity at human scales

The nice people at Ars Technica wrote about a Science paper published today. Through the use of precise optical clocks, researchers were able to show the effects of relativity for objects in motion and at different distances from a massive object (i.e. Earth). Traditionally, effects become “obvious” and large when objects move at near light-speed. It is interesting then to see that macroscopic objects (like huge clocks and by extension, things and people) can also experience relativity, albeit with inconsequential effects. Researchers were able to show that moving a clock at 22 mph or placing a clock about 1 ft higher off the ground will result in that clock ticking slower. Both are good reads.
