The Latest Breaking News from Radiation

The universe is smoother than the standard model of cosmology suggests – so is the theory broken?

Given how unfathomably large the universe is, it is perhaps understandable that we haven’t yet cracked all its secrets. But there are actually some pretty basic features, ones we used to think we could explain, that cosmologists are increasingly struggling to make sense of.
