Eighty years after the first atomic bombs fell on Hiroshima and Nagasaki, experts and survivors warn that the risk of a new ...

The launch of this new tracking system is set to coincide with the 2025 Doomsday Clock time announcement — a metaphorical warning from the Bulletin of the Atomic Scientists about how close we ...

One of the biggest challenges in modern physics is uniting quantum mechanics and general relativity. A new experiment may ...

This clock would be better than other atomic clocks, according to physicists, because it uses optical light instead of microwaves. The former, because of its higher frequency, provides more ...

Scientists propose using quantum-entangled clocks to test how gravity affects quantum mechanics in curved spacetime.

Up and atom "Today's atomic clocks enable GPS systems with a positional accuracy of a few meters [where 1 meter is 3.3 feet]. With an optical atomic clock, you may achieve a precision of just a ...

The most precise and accurate atomic clock in the world, the ultracold strontium clock at JILA in Boulder, is like a stopwatch that can count the billionths of a nanosecond, or 18 digits past the ...
