Time feels familiar. It marks every moment of daily life, from the ticking of a wall clock to the changing numbers on a ...

Last week, we touched upon E=mc2, and how Einstein’s theory of relativity turned the world of physics upside-down. Now, we’re using that theory to show why the very concept of time may not be what you ...

Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity. Now a new theoretical study pushes that weirdness into even stranger territory. It ...

In a dual set of papers published in Science last week, an international group of researchers presented an experiment which used relativistic time dilation to measure the curvature of spacetime. The ...

Using one of the world's most precise atomic clocks, physicists have shown that time runs a tiny bit slower if you change your height above the Earth's surface by a minuscule 0.008 inch (0.2 ...
