Physicists have now seen waves “bounce” off a sudden change in time itself—a twist that flips their direction and shifts their pitch. It isn’t time travel, ... Continue Reading → ...

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 ...

Clocks might be far more fundamental to physics than we ever realized. A new theory suggests what we see around us – from the smallest of quantum actions to the cosmic crawl of entire galaxies – could ...

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 ...
