Sorry, but I cannot get excited about the Large Hadron Collider (LHC). I find it hard to see how it is going to reveal the secrets to the universe, or even to produce new scientific insights comparable to the expense and effort involved.
First, I find it hard to believe that the Higgs boson will not be found. My limited knowledge of particle physics and the standard model is that it just has to be there. Spontaneous symmetry breaking and the associated dynamical mass generation is well established in other areas of physics (e.g. the Meissner effect in superconductors can be viewed as photons acquiring mass, as first emphasized by Anderson). Hence, I won't be surprised if it also works / is present in the Standard model via the Higgs boson.
On the one hand, the LHC (search for the Higgs boson) is an experiment that should certainly be done, in a world in with almost unlimited resources for science.
On the other hand, I remain to be convinced that the LHC is a much better investment than "tabletop science." The latter has produced Graphene, violations of Bell inequalities, spin ice, fractional statistics in the quantum Hall effect, and cuprate superconductors. To me anyone of those is of comparable importance to confirming the Higgs boson is really there.
An earlier post considered the second of Two questions physics can no longer avoid, asked by Martin Gutzwiller in a Letter to Physics Today, published in August 1994.
His first question was, "Has particle physics fulfilled its promise?"
