There’s something very odd going on in space – something that shouldn’t be possible. It is as though vast swathes of the universe are being hoovered up by a vast and unseen celestial vacuum cleaner. Sasha Kaslinsky, the scientist who discovered the phenomenon, is understandably nervous: ‘It left us quite unsettled and jittery’ he says, ‘because this is not something we planned to find’. The accidental discovery of what is ominously being called ‘dark flow’ not only has implications for the destinies of large numbers of galaxies – it also means that large numbers of scientists might have to find a new way of understanding the universe. Dark flow threatens to re-write the textbooks. Does it herald a new era of understanding, or does it simply mean that everything we know about the universe is wrong? DID YOU KNOW? Nasa scientists discovered that distant clusters of galaxies seemed to be shifting towards the same spot in the sky, beyond the boundary of what we can see. The flow cannot be accounted for by the observed distribution of matter in the universe. |
