Can the time-warping ways of Einstein's theory of general relativity be measured by the quantum 'ticking' of an atom? In 2010, researchers at the University of California, Berkeley, claimed in Nature ...

Time feels like the most familiar thing in the world, yet it hides one of physics’ hardest questions: why do we only remember ...

It's 2 a.m., and the noise from your upstairs neighbor is keeping you awake again. Take solace in the fact that by living above you he may be shortening his life, even if only by a tiny fraction of a ...
