There is an excellent response on the BBC site to those questioning the expense of the LHC in general, and by the current head of the British Association for the Advancement of Science in particular. The LHC is a marvellous endeavour and suggesting that the money would be better spent on climate change, or medical research is missing the point. We need to do both, and more. Humanity needs to explore. We need to probe the quantum realm. We need to explore the cosmos. We need to research for new medical advances. We need to find new cleaner energy sources. We need to do lots of things, but not at the expense of basic research into the way the Universe functions. The money spent on the LHC is not that much in comparison to other national expenditure. The UK contribution is equivalent to the cost of a pint of beer per head per year. It’s peanuts. Both figuratively and in a real sense. More is spent in the UK on peanuts every year than the UK contributes to the LHC. Maybe we should stop pouring money down the Iraq rat hole if we want to save. I’m looking forward to many years of interesting data and results from the LHC.
