                                    People age faster—very, very slightly faster—the higher above ground they live, according to scientists testing Einstein's theory of relativity. Researchers using ultra-precise atomic clocks found that time, as Einstein predicted, is slowed down by gravity even over minuscule distances. The scientists found that just moving a couple of...
