Physicists have created atomic clocks, in detail, that can measure deformations over time, according to the new study.
We do not spend the same period of experience as time goes by, closer to a giant gravitational approach, as Albert Einstein is familiar with. In fact, since gravity usually interprets the massive circulation of space, the exact atomic clock is sufficient, the object can serve as a scientific tool for measuring the shape of the surrounding space.
"We measure two watches, initially, to enable our account [this effect] On the Earth's surface, "said Andrew Ludlow, a physicist at the Boulder, Colombian National Institute of Standards and Technologies, said Gizmodo.
They are just tools that measure how much time they spend in real time, swinging pendulum or vibrating atom. Optical cable networks, like those used in the research, work the same way, but not so much.
Scientists use Lasers for the first time to configure the atom capture zone as a cup row. Thousands of ytterbium atoms make up each cup. If the laser is directly applied to the right frequency, the electrons will fall between two energy levels, very large (almost a quadratic), but a precise amount of seconds per second. Once the laser is tuned to the perfect frequency, this oscillation begins to move to another component, called the optical frequency comb. This is basically a watch gear, making the laser light a signal so you can use the electronic signature.
Here, the researchers basically have high accuracy in measuring high frequencies, which measure how influenced the gravity measures, according to the paper published in Nature. A couple of optical ytterbium watches have detailed the frequency of Ytterbium transitions in the 10s-18 Actual frequency, changing up to 3.2 x 10-19, the frequency of two watches is approximately 10%-19. The watches with these accuracies would last more than the age of the universe (13.8 million years) to lose a second.
But the clocks were characterized so that the Ytterbium watches slowed Earth's gravity, and decided to determine the Earth's gravitational field accurately within a centimeter. It is better than the state of the earth measuring systems. Ludlow has explained that the team does not compare the clocks in two different locations, yet. Such a test marks the speed of the higher clock faster, as the object of gravity on the Earth decreases gradually as the object moves at a higher altitude.
World efforts are the only end result of the best atomic clocks. But it's a fantastic development, said Andrei Derevian, theoretical physicist at the University of Nevada, Reno, but he did not participate in this research, but he worked in the theory behind these clocks. As Gizmodo said, with this level of precision watches are still looking for a "killer app".
But the fact that the physicist uses these ideas, especially when hunting the dark matter that we see directly from the eyes and telescopes, seems to create a gravity force throughout the universe. Perhaps these clocks could detect dark matter, their gravity changes their space time. Perhaps space spots called gravitational waves can also be seen. Or maybe it's moving to atomic clocks in space, because local differences in the gravity of the Earth cause less. It's hard to say.
No, you can not hang your watch on your wrist or hang it on your wall, still a laboratory-based setup. But if you can not, it may be quite ill to tell your friends late, because their local potential gravity is too high.[Nature]
