Japanese invented the most accurate clock.

The world's most accurate clock: Scientists create way of measuring time that loses just one second every 16 BILLION years

• Japanese researchers have created super-accurate optical lattice clocks
• They are 1,000 times more precise than the most accurate atomic clocks
• They are made using super-cooled atoms held in a lattice of laser beams
• Scientists say their clocks would have lost less than one second if they had running from the moment the universe was born with the Big Bang
• They say the devices could help understand and predict earthquakes
