"In fact, the vacuum is full of various particles that are continuously fluctuating in and out of existence. They appear, exist for a brief moment and then disappear again. Since their existence is so fleeting, they are usually referred to as virtual particles."

"...space should be grainy at the smallest scales, like sand on a beach. (...) According to calculations, the tiny grains would affect the way that gamma rays travel through space."

"At present it is ascertained that vacuum is not an "empty space" - rather, it is a certain material continuum with quite definite although still unknown properties. This has been confirmed by observation of vacuum effects such as "zero-oscillations", vacuum polarization, particle generation by electromagnetic interactions. Therefore it is reasonable to suggest that physical vacuum could have internal friction due to its own small but real viscosity, which in the end produces redshift. (...) ...the differential equation for the speed of light dc/dt=-Ho*c(t)"
HYPOTHESIS: As the photon travels through space (in a STATIC universe), it bumps into "virtual particles" or "tiny grains" and as a result loses speed in much the same way that a golf ball loses speed due to the resistance of the air.
On this hypothesis the resistive force (Fr) is proportional to the the velocity of the photon (V):
Fr = - KV
That is, the speed of light decreases with time in accordance with the equation:
dV/dt = - K'V
Clearly, at the end of a very long journey of photons (coming from a very distant object), the contribution to the redshift is much smaller than the contribution at the beginning of the journey. Light coming from nearer objects is less subject to this difference, that is, the increase of the redshift with distance is closer to LINEAR for short distances. For distant light sources we have:
f' = f(exp(-kt))
where f is the original and f' the measured (redshifted) frequency. (The analogy with the golf ball requires that it be assumed that the speed of light and the frequency vary while the wavelength remains unchanged.) For short distances the following approximations can be made:
f' = f(exp(-kt)) ~ f(1-kt) ~ f - kd/L
where d is the distance between the light source and the observer and L is the wavelength. The equation f'=f-kd/L is only valid for short distances and corresponds to the Hubble law whereas the equation f'=f(exp(-kt)), by showing that later contributions to the redshift are smaller than earlier ones, provides an alternative explanation, within the framework of a STATIC universe, of the observations that brought the 2011 Nobel Prize for Physics to Saul Perlmutter, Adam Riess and Brian Schmidt. The analogy with the golf ball suggests that, at the end of a very long journey (in a STATIC universe), photons redshift much less vigorously than at the beginning.
