The world’s best clocks may be sensitive to an odd mix of quantum and relativistic effects that would stretch time and test ...

Physicists from Imperial College London have achieved a groundbreaking milestone in quantum physics by reimagining the ...

Atomic clocks record time using microwaves to measure the frequency of quantum vibrations of electrons. They are the basis upon which a second is defined. But there’s a new kid on the block, the ...

Time, not space plus time, might be the single fundamental property in which all physical phenomena occur, according to a new theory by a University of Alaska Fairbanks scientist. The theory also ...
