Scientists Create a Nuclear Clock So Precise It Barely Loses a Second in 30 Million Years

A self-stabilizing nuclear clock has achieved precision equivalent to roughly one second in 30 million years, though it still trails the best optical atomic clocks. For a clock that keeps time with laser light, even a slight shift in the laser’s frequency changes its rhythm. Researchers in Vienna have now built the world’s first nuclear [...]
