World's most accurate clocks are synchronised to a quadrillionth of a second - and it could change how we define time

Time may be relative, but physicists are a stickler for accuracy.
While many of us may give a few minutes’ grace to the timepieces in our homes, one group of scientists has successfully synchronised a pair of optical clocks to within a million billionths of a second.
By measuring time to such a fine point of accuracy, physicists could ultimately change the length of a second.
SUPER ACCURACTE CLOCKS  Physicists in the US fired a laser beam between two buildings more than seven miles (12 km) apart.
At either end they used optical clocks to detect regular laser pulses every five nanoseconds –... read more
