Dark matter: our review suggests it's time to ditch it in favour of a new theory of gravity

Null

We can model the motions of planets in the Solar System quite accurately using Newton’s laws of physics. But in the early 1970s, scientists noticed that this didn’t work for disc galaxies – stars at their outer edges, far from the gravitational force of all the matter at their centre – were moving much faster than Newton’s theory predicted. This made physicists propose that an invisible...
