In 1999, two groups of astronomers made a remarkable discovery; the expansion of the Universe was accelerating not slowing as expected. In just over a decade, this amazing observation has been comprehensively confirmed and is now rewarded with a Nobel Prize in Physics in 2011. But why is the Universe accelerating? The answer to that question remains elusive but has fuelled the imagination of thousands of scientists across the globe. In this talk, Bob will give a lighthearted summary of the science behind the discovery of the accelerating Universe and review his (small) part in confirming this phenomenon. He will conclude with speculation about what could be causing all this fuss.
