Default The Failure of Mainstream Cosmology

I made two more comments but Adrian Cho rejected them:

HYPOTHESIS: As the photon travels through the viscous vacuum (in a STATIC universe), it loses speed analogously to a golf ball losing speed due to the resistance of the air.

On this hypothesis the resistive force (Fr) is proportional to 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 effect, 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 initial and f' the measured (redshifted) frequency. For short distances the following approximations can be made:
I
f' = f(exp(-kt)) ~ f(1-kt) ~ f - kd/λ

where d is the distance between the light source and the observer and λ is the wavelength. The equation f'=f-kd/λ is only valid for short distances and corresponds to the Hubble law. The equation f'=f(exp(-kt)) shows that, at the end of a very long journey (in a STATIC universe), photons redshift much less vigorously than at the beginning of the journey. This provides an alternative explanation of the observations that brought the 2011 Nobel Prize for Physics to Saul Perlmutter, Adam Riess and Brian Schmidt.

Here is a similar interpretation:

http://arxiv.org/pdf/physics/9911069.pdf
Eugene I. Shtyrkov, The Evolved-Vacuum Model of Redshifts: "There are also alternative models of redshifts which obey the redshift-distance relation and based on an idea of gradual change of light parameters due to interaction between light and matter while the light is traveling gigantic distances through space for a very long time. There are two candidate ways for such interaction to cause redshifts: gradual energy loss by the photon due to absorption during propagation of light with a constant velocity (tired-light model, see, for instance, [8]) and propagation of light with the variable velocity and without absorption in free space (variable-light-velocity models). [...] Thus we come to a very important conclusion: the induction wave, and hence the light one, must travel in vacuum with conservation of wave length even when the parameters are time dependent. [...] ...we obtain a simple differential equation for the light velocity: dc(t)/dt = -Ho.c(t) (15) [...] Although reproducing the conclusions of the tired-light model, namely, about simultaneous decreasing the electric field strength and frequency, this model has a different physical interpretation. Instead of energy loss due to absorption at constant light velocity, this mechanism is based on gradual change of the vacuum parameters that results in declining of the electric field strength. The electromagnetic wave is gradually slowing down, with conservation of the initially shifted wavelength (lambda)_shift. The frequency perceived by observers at any point on the light path depends on the light velocity at the observation time."

Clearly variable-speed-of-light interpretations of the Hubble redshift (for a STATIC universe) converge to an equation of the type dc(t)/dt = -Ho.c(t) (I presented it as dV/dt = -K'V).

Dark energy is a fudge factor - now other fudge factors will replace it. Unlike special relativity, general relativity is empirical, not deductive. It was not deduced from postulates (has no postulates). General relativity was the result of endlessly changing and fudging equations until some final version managed to match known in advance experimental results and pet assumptions. And fudge factors belong to the essence of general relativity.

Can one introduce a fudge factor analogous to the cosmological constant in Lorentz transformation equations? One cannot, and the reason is simple: Special relativity is DEDUCTIVE (even though a false assumption and an invalid argument have spoiled it from the very beginning) and fudging is impossible by definition - one has no right to introduce anything that does not follow from the postulates.

The only alternative to deductive theory is empirical concoction (a "theory" that is not even wrong) - Einstein clearly explains this he

Albert Einstein: "From a systematic theoretical point of view, we may imagine the process of evolution of an empirical science to be a continuous process of induction. Theories are evolved and are expressed in short compass as statements of a large number of individual observations in the form of empirical laws, from which the general laws can be ascertained by comparison. Regarded in this way, the development of a science bears some resemblance to the compilation of a classified catalogue. It is, as it were, a purely empirical enterprise. But this point of view by no means embraces the whole of the actual process ; for it slurs over the important part played by intuition and deductive thought in the development of an exact science. As soon as a science has emerged from its initial stages, theoretical advances are no longer achieved merely by a process of arrangement. Guided by empirical data, the investigator rather develops a system of thought which, in general, is built up logically from a small number of fundamental assumptions, the so-called axioms."

Special relativity was indeed "built up logically from a small number of fundamental assumptions" but general relativity was, to use Einstein's words, "a purely empirical enterprise". Einstein and his mathematical friends changed and fudged equations countless times until "a classified catalogue" was compiled where known in advance results and pet assumptions (such as the Mercury's precession, the equivalence principle, gravitational time dilation) coexisted in an apparently consistent manner. Being an empirical concoction, general relativity allows Einsteinians to introduce, change and withdraw fudge factors until the "theory" manages to predict anything Einsteinians want. Then the prediction turns out to be confirmed by observations (surprise surprise).

The fudge-factor activity is inglorious and Einsteinians don't discuss it openly, but sometimes the truth comes out inadvertently. So conventional dark matter models based on general relativity "need four free parameters to be adjusted to explain the data" (how many fudge factors LIGO conspirators needed in order to model the nonexistent gravitational waves is a deep mystery):

Quote: "Verlinde's calculations fit the new study's observations without resorting to free parameters – essentially values that can be tweaked at will to make theory and observation match. By contrast, says Brouwer, conventional dark matter models need four free parameters to be adjusted to explain the data.
