Dark energy mystery is finally SOLVED - as scientists come up with a radical new theory to explain the mysterious force

Daily Mail  

Dark energy, one of the most mysterious concepts in astronomy, has baffled the world's greatest minds for decades. Lead author professor David Wiltshire says: 'Our findings show that we do not need dark energy to explain why the Universe appears to expand at an accelerating rate.' Scientists claim to have solved the mystery of dark energy by showing why we …
