Picture a clock ticking so steadily that it doesn’t lose a second, even after running for 1 billion years. Scientists are now closer than ever to realizing that level of timekeeping precision ...

Many modern atomic clocks use oscillations of strontium atoms rather than cesium to measure time; the most precise of these is accurate to within 1/15,000,000,000 of a second. This means that ...

Picture a clock ticking so steadily that it doesn’t lose a second, even after running for 1 billion years. Scientists are now closer than ever to realizing that level of timekeeping precision ...

Atomic clocks are the world’s most precise timekeeping devices, and they are essential to staples of modern life such as global positioning systems, telecommunications and data centres. The most ...

Scientists have found that Earth is spinning slightly faster than normal, resulting in shorter days, though the reason ...

Atomic clocks only deviate by one second in millions of years. Nevertheless, even more precise timepieces are sometimes needed for basic research. Researchers at the Vienna University of ...

Optical atomic clocks function not through gears and pendulums but through the orchestrated rhythms between atoms and excitation laser. QPN poses a fundamental obstacle to the precision of these ...

The clock – using quantum technology – records time with the precision of losing less than one second over billions of years. The ‘Demonstration of Advanced Timing Apparatus’ (DATA) is part of a ...

Traditional atomic clocks, although precise, use microwaves to measure time. Optical atomic clocks, on the other hand, use laser light for even greater precision.

The researchers said a nuclear clock would have major advantages for clock precision over current technology. Atomic clocks measure time by tuning laser light to frequencies that cause electrons ...
