Has Jupiter been leading science astray?
In 1998 astronomers had a bit of a shock when it was revealed that our universe was not behaving as it ought. They had believed that since the Big Bang hurled our universe into existence, its expansion must, inevitably, have been gradually slowing down. It came as no small surprise then when it was revealed that its expansion was actually accelerating and that we seem to be missing some 96 per cent of its matter.
To explain this curiosity, cosmologists summoned up a mysterious, invisible and undetectable force, called ‘dark energy’, and a barely detectable, invisible material called ‘dark matter’ (see next page). And everyone lived happily ever after (except for those who disagreed and thought it was all just imaginary bunkum). Until now.
