One wonders why this simple observed fact does not percolate down to the masses that

Planck scale 'foaminess'!
The zero point energy of a field is negative for bosons (like photons) and positive for
fermions. The theory predicts _+_hbar*w/2 for each degree of freedom (e.g. 2 for a
photon). This is what produces what Weinberg called the "worst prediction in theoretical
physics". But if you use the holographic principle and count only the degrees of freedom
proportional to the surface area (instead of volume) of the hubble sphere you get an
energy density close to the observed dark energy value.
