What if Nobel Prize winning science was wrong? And not wrong in a small way… Wrong in a way that changes everything we think we know about the Universe. That's the big argument that’s raging in cosmology right now. In 1998, two teams of astronomers discovered that the Universe isn't just expanding, the expansion is accelerating. Dark energy is pushing it apart faster, but we still don’t really know what it is yet. That’s what won the Nobel Prize in Physics back in 2011, and has since become one of the pillars of our best model of the Universe. But recently a group of cosmologists, Son et al., have claimed the supernovae data used to make the discovery has been hiding a bias for thirty years. Which when you correct for that bias, switches the acceleration of the Universe’s expansion rate to a deceleration. At the heart of this latest scientific discussion is a question that every cosmologist recognises as a big problem: do we really understand the supernovae we've been using as our c
