As of early 2013, I don't think it has been≥
Higgs boson was created in 2011.
We are not sure if the theorized Higgs boson is real or not. If it is, it would be provide some support to ideas about what mass (and, therefore, gravity, which is associated mass) really is. We're still looking for experimental support that the Higgs boson is real, and now that the Large Hadron Collider is up and running, all (interested) eyes are on CERN and awaiting results.
The "Higgs Field".
It will prove the existence of the Higgs Boson. So far it is only theory. This is a groundbreaking result as particle physics has been without new data for over a decade to decide what theories are correct.
The Higgs boson was first discovered on July 4, 2012 at the Large Hadron Collider (LHC) at CERN in Switzerland. The discovery was a significant milestone in particle physics and confirmed the existence of the Higgs field, which gives particles mass.
The Higgs boson, is well, a boson. All bosons follow Bose-Einstein statistics and are therefore CAN occupy the same quantum state (as opposed to fermions, i.e. matter, which cannot.) So basically, no. The Higgs boson does not occupy any space.
The Higgs Boson is called the "God" particle because it would help explain on of physics biggest mysteries: how gravity works. Can both God and the Higgs Boson exist? Yes, if God exists, then he could have created the Higgs Boson, like he created other particles.
the Higgs Boson
not yet
It is a boson, a type of particle, that is a part of the Higgs mechanism, a theory of how particles can have mass if they are just energy
The facility that found the most unambiguous evidence for the reality of the Higgs Boson is CERN.
