Believe a clock that are only late one second each 200 million years

A while ago he spoke of an extraordinary clock that were only delayed one second each six million years. Something incredible although as always in this récords type, one wait is overcome as the technology advances. Now then, the new record overcomes, and for a lot, to the previous one. And you are that American physiques have designed such a precise clock that you won't lose neither you will win neither one second in 200 million years, a discovery to the height of those obsessively punctual.

The clock, described in the magazine Science, fights to transform conjointly into the most exact in the world with the experimental other clock developed in the same lab of Joint Institute for Laboratory Astrophysics (JILA).

"These clocks are improving so quickly that you are impossible to say which the best will be, you said Tom 0Brian, boss of the division of Time and Frequency of NIST.

The clocks of great acuity are vital for the aerospace sailing, where a minimum error can ruin a commission. The secret of the so exact operation is to accelerate the movement of the needles, concretely this clock, carries out 430 trillion movements per second.

Your pendulum uses thousands of suspended strontium atoms in grids of laser light, and this allows the investigators to catch the atoms and to measure the energy movement inside them.

As future applications, these clocks can be used to synchronize the networks of telecommunications and some day to allow other advances as handless on file conduction guided by satellite. "If we can make to move a vehicle in Mars and to request you that you stay in a specific channel, I am for sure we can browse all the cars of the earth with satellites", one of the investigators assures.

"Essentially, we are sounding the structure of energy of the atom. We are sounding how they make the transitions the electrons among different energy" levels. This is the scale of time that were created by the universe. You are very stable", you concluded.
