  Shown is that contrary to common intuition, even an arbitrarily weak
attenuating mechanism is sufficient to make the background sky quite dark
independently of the size of the universe and the Hubble expansion. Further
shown is that such an attenuation already exists in the wave nature of light
due to entrapment and diffusion from successive diffractions. This is a
fundamentally new mechanism to physics, as illustrated by application to the
solar neutrino attenuation, galactic dark matter and gamma ray bursts problems.
It not only provides a big bang-like cutoff, but also appears to explain the
appearance of primeval, metal-deficient galaxies at high redshifts, without
deviating from the Olbers' premise of an infinite universe.
