One way we make sense of the cosmos is to study what's in it, objects like this brown dwarf (artist's impression) observed by the ESO's ALMA project. Another way is to watch what happens when tiny particles are smashed together in "labs" such as the LHC at CERN. M. Kornmesser/ALMA/ESO/NAOJ/NRAO hide caption
