It looks like the search for the elusive Higgs particle is getting close. The so-called Standard Model of particle led to the existence of the Higgs being proposed 1964 as an explanation of how elementary particles get their mass and it is the final particle of the model to be yet directly detected. If it is not found, that would require us to re-think some important theories of particle physics.
They are hoping for something definite to emerge within the next year. But if the Higgs is not found by then, the search may drag on longer because concluding that something is not there is more difficult than concluding that it is.
