^ It's not that they "finally found something". They found the particle that they built the large hadron collider to look for. Not to mention the fact that the higgs boson particle is incredibly important to particle physics.
It is an incredible day in the development of physics. Thought it was not found to be THE Higgs Boson. It was found to be a Higgs-like boson. The important part is though that the current model of particle physics predicted that this particle would exist within the determined energy range and they certainly did find a particle in this range which is a great experimental confirmation of the current standard model and gives plenty to research.
