New Atomic Clock 1000 Times More Accurate

Posted by CowboyNeal on from the chronographs-and-tickers dept.

stevelinton writes "The UK National Physical Laboratory has a new atomic clock potentially 1000 times more accurate than current cesium clocks: to within 1 second in about 30 billion years! This could lead quite soon to a new definition of the second, and in a while to improved resolution in GPS successor systems. More interestingly, there are theories that some of the universe's fundamental dimensionless constants may have changed by a parts in a million over the last 10 billion years or so. These clocks are so accurate that they should be able to detect these changes over a year or two."

    Fuck metric!

    For example, no observer could stand outside the universe, because there's nothing outside the universe.

    You know this for a fact? You have directly observed that we are not, in fact, a giant simulation being carried out in a higher level of reality (the real, or more real world)? You can see that we are not 1 of zillions of parallel universes. (Oxymoron, I know.) That is awesome! Now I know there is a God - You! Only Deity could be so intimately aware of everything that is, was or ever will be. Only Deity could be so absolutely, perfectly, amazingly omniscient! Thank you for sharing with us your Divine knowlege, and telling us humble earth dwellers what we could never know for certain on our own.
