Scientists have achieved a new record in accurate timekeeping by making an atomic clock that loses a mere second ever 15 billion years, which is a span time greater than the estimated age of the universe. The clock measures the oscillation of strontium atoms to create its tick and could become the standard for the official time of the world, which is the standard of UTC, which uses the element caesium at the moment, which are only accurate in the region of one second in hundreds of millions of years.
Otherwise known as the optical lattice clock, the strontium clock has been in development for a number of years and previously broke the timekeeping records in the year 2013. However, a series of modifications outlined in the journal Nature Communications made it thrice as accurate. In fact, the precision level of the clock is so high that raising it just 2 centimeter above the Earth’s surface shows a significant effect, with even this minuscule change in gravity picked up by the tick of the clock.
Despite its insanely accurate properties, some concepts such as measuring the shape of Earth cannot be done by the strontium clock compared to other conventionally used methods, since scientists suggest that it would need to measure an elevation difference of just one centimeter to be useful. Hence, the clock’s creators will have to be satisfied with the other wide range of benefits from the accurate clock such as accurate timekeeping, improving navigation and GPS (Global Positioning System) and pushing the boundaries of quantum physics.
