Scientists from the National Institute of Standards and Technology in Boulder, Colorado, have invented a new clock that can even detect dark matter. The clock is extremely precise that won’t gain or lose more than a second in a span of 14 billion years.
New Atomic Clock – An Exceptional Tool for Scientists
The clock can calculate the exact shape of Earth’s gravitational field and can measure the gravitational waves that flow across the universe. However, any individuals on regular basis do not require this type of precision. But it can be useful to for scientists, physicists, and similar others in the same profession. Moreover, by using this clock, the scientists can investigate the mysteries of the cosmos.
In 1960, an atomic clock was used to measure the time that mainly used natural oscillation of a cesium atom as a pendulum. To understand more clearly, take it as a watch whose hand ticked nine million times per second. On the other hand, the optical lattice clock developed by Ludlow and his colleagues measured faster oscillation of an ytterbium. The atomic pendulum in it clicked ten thousand times faster. The speed of the pendulum was five hundred times per second.
The optical lattice clocks are in existence from last 15 years, and it is still in its development stage. Scientists are continuously tinkering with them and increasing its accuracy with every new adjustment.
Moreover, the experiment performed by the team is to understand similar types of gravitational waves that were witnessed in the LIGO observatory. It is done to affirm Einstein’s signature theory.
