Huge if true – dark energy doesn’t exist, claims new study on supernovas

An illustration of the death of a massive star. NASA/Goddard Space Flight Center/Dana BerryBy looking at light from distant exploding stars called supernovas, in 1998 astronomers discovered the universe isn’t just expanding – its expansion is speeding up. But what’s behind this acceleration? Enter dark energy. It’s one of the most debated and intriguing missing puzzle pieces of modern physics – a mysterious form of energy believed to uniformly p…

Ask Ethan: Can a lumpy Universe explain dark energy?

Our Universe isn't just expanding, the expansion is accelerating. Instead of dark energy, could a "lumpy" Universe be at fault?
