A physicist built a ‘mini-universe’ out of ultracold atoms and watched time being born inside it.
For the first time, a physicist has experimentally watched time emerge from within an isolated quantum system —…
Scientists may have finally solved the black hole information paradox
For decades, physicists have wrestled with one of the deepest puzzles in modern science: the “black hole information…

We tend to think of the universe as roughly uniform, with galaxies scattered in every direction — but the Boötes Void, discovered in 1981 during a redshift survey, is a vast cosmic underdensity up to 330 million light-years across, containing only a few dozen known galaxies where thousands might otherwise be expected
On the scale of the whole observable universe, matter is assumed to be spread out fairly evenly: enough…
