Yeah, right (i mean you read right)Scientists have built a clock which is 100,000 times more precise than the existing international standard(the atomic clock) called as (drum roll…..) Quantum Logic Clock)
The quantum-logic clock, which detects the energy state of a single aluminum ion, keeps time to within a second every 3.7 billion years as compared to the current standard Cesium Fountain clock which loses one in sec in every 100million years. The new timekeeper could one day improve GPS or detect the slowing of time predicted by Einstein’s theory of general relativity.
The clock could help resolve questions about the universal physical constants, such as the speed of light in a vacuum, or Planck’s constant, an important value in quantum physics.
Physical constants are supposedly fixed over time, but some theories suggest they may vary slightly.
Global positioning devices also rely on extremely precise atomic clocks, so “if we have better and better clocks then we can tell our position, to a better and better precision.
And the clocks could also show the effects of general relativity by detecting how much gravity warps time.
