A random blobby universe of dark matter.
Hundreds of scientists have carried out the largest survey of dark matter in the universe, and released the first tranche of results. It's a staggering bit of research, involving observations 100 million galaxies with some of the finest astronomical imaging gear on the planet. And guess what? Einstein was wrong! Or, well, that's what some headlines screamed. The reality is a little more nuanced: there are some intriguing discrepancies between models and experiments, and lots more work to do.
