astroengine writes: "It's to be expected when pushing the frontiers of physics, but the LHC's epic "will it or won't it" saga continues. Due to an unforeseen construction mistake, the LHC will cease experiments for a year (starting around late-2011) so repairs and upgrades can be carried out. For now, accelerated particles will have a maximum energy of 7TeV (half the power of the LHC's design maximum), which is ample for at least 18 months of experiments before shutdown."

"The fundamental principle of science, the definition almost, is this: the
sole test of the validity of any idea is experiment."
