those interested, there is an interpretation of |

| scalar
Higgs fields under quantum field theory (see |

| Zeldovich
1986). |

point vacuum fluctations associated with zero |
||||||||||
| point
energies of quantum fields results in a |
|||||||||||
| negative
energy equation of state (having “tension” |
|||||||||||
| rather
than “pressure”). Quantum field
theory can |
|||||||||||
| then
make predictions about the value of a |
|||||||||||
| cosmological
constant – and is off by some 120 |
|||||||||||
| orders
of magnitude! Works for inflationary |
|||||||||||
| period,
but not now. |
