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…

Scientists thought the universe was uniform. New evidence says otherwise
The shape of the universe is not something we often think about. But my colleagues and I have…

In 1851, a French physicist suspended a metal ball from a 67-metre wire, and it became one of the first direct proofs that the Earth rotates |
Most of us accept that the Earth rotates because we have been taught it since childhood. We have…
