To get the observed particle masses, the background Higgs field that exists throughout the universe has to have an incredibly high density of energy and mass. Which one might expect would have a huge gravitational effect—in fact, enough of an effect to cause the universe to roll up into a tiny ball. Well, to avoid this, one has to assume that there’s a parameter (a “cosmological constant”) built right into the fundamental equations of gravity that cancels to incredibly high precision the effects of the energy and mass density associated with the background Higgs field.

And if this doesn’t seem implausible enough, back around 1980 I was involved in noticing something else: this delicate cancellation can’t survive at the high temperatures of the very early Big Bang universe. And the result is that there has to be a glitch in the expansion of the universe.

A few days old, but this post by Stephen Wolfram really made the whole Higgs Boson situation much clearer to me. Particle physics is basically science bent asymptotically towards the point of magic.
