I'm pretty sure it's a name given to the Higgs boson, right? That's what I've heard about it anyway. I think it was given that name because, if people could find it and understand it, they'd understand many of the fundamental principles of physics and the universe and junk.
...That's just what I've heard. I'm not sure if my explanation is totally accurate.
I definitely don't doubt the Higgs boson exists, not at all.
