Einstein's theory of general relativity holds that a massive body like Earth curves space-time, causing time to slow as you approach the object—so a person on top of a mountain ages a tiny bit faster than someone at sea ...

(Phys.org)—While hypothesized dark energy can explain observations of the universe expanding at an accelerating rate, the specific properties of dark energy are still an enigma. Scientists think that dark energy could take ...
Thanks to the presence of a natural "zoom lens" in space, University of Chicago scientists working with NASA's Hubble Space Telescope have obtained a uniquely close-up look at the brightest gravitationally magnified galaxy ...
