Exact Clock with secondsPrecise clock with second indication
Ticktering times are sensed by microwave waves radiated by an electron around an atom that jumps from a lower to a higher trajectory as it absorbs and then loses power from a lasers.
However, these watches are limited in their accuracy, because when cesium-electrons jump from one state to another, they are emitting rays with a mere 9 gigahertz or 9 billion cycles a second. At 429,500 giga-Hertz, the electron in streontium atom emits rays. "In 2014, the world's most precise visual clock would not loose or win a second in the whole era of the universe," says Jun Ye of the University of Colorado at Boulder.
So far, esium watches have kept the exact timing over a period of 300 million years. Now Yes Group has constructed a chronometer that is so accurate that out of 10 trillion tricks, only 3.5 would be out of synch - the first ever astronomical clock to achieve this accuracy.
In order to make a more accurate clock, Ye and his crew created a 3-D design that allows them to suddenly detect multiple atomic signatures within the width of the ray. However, if you wrap too many, the collision between electrons can blur the collision between them. Trellis allowed scientists to study much more tightly packaged atomic structures - 10 trillion atom s/cubic cm in comparison to earlier watches with 10 billion atom s/c cm - and to better monitor the interaction of these atom s/c, thereby minimizing the frequency of their collision.
Closer timepieces will allow us to test theory such as Einstein's general theory of gravity - which says that timepieces run differently when they are subjected to different gravity powers - and look for gravity surges that change the course of motion of our times in deeper spaces. Though it is the most precision atomic clock ever made, it hasn't run long enough to tell how exactly it will stay over the course of anything, Ye says.
Lisdat from the Physikalisch-Technische Bundesanstalt in Germany is interested in how the 3-D grid layout will affect the precision of the clock, but he is confident that the results are correct. We' ve adjusted the mechanisms of the nuclear clocks.
