fit with the laws of general relativity, which describe the universe on the largest scales? The optical lattice clock, one of the most precise timekeeping devices, is becoming a powerful tool used ...

Precision equipment manufacturer Shimadzu Corp. said it has created the world’s most accurate time device: a clock that won’t ...

Optical lattice clocks, the pinnacle of timekeeping, are key to exploring the relationship between quantum mechanics and gravity, advancing fundamental physics.

Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short description from the ...

General relativity states that all matter in a black ... Likewise, there is no clock that divides the passage of time into arbitrarily fine intervals—it progresses in steps, like the second ...
