I keep hearing this dubious term that is used to explain away discrepancies in the calculation of galaxy angular momentum as it relates to mas estimations. So far computor simulations are postulating that galaxy spin should be significant slower.

Maybe the damn formula is just plain wrong!!

p. 885 “According to inflationary cosmology(1-3), the universe expanded exponentially quickly for a fraction of a second very early in its history— growing from a patch as small as 10 ^(-26) m, one hundred billion times smaller than a proton to macroscopic scales on the order of a meter, all within about 10^(-35) s- before slowing down to the more stately rate of expansion that has characterized the universe’s behavior ever since.. .
.. . in fact inflationary cosmology leads to several quantitative predictions about the present behavior of our universe—predictions that are being tested to unprecedented accuracy by a new generation of observational techniques. So far agreement has been excellent.. .

[predictions] First, our observable universe should be spatially flat [BOM the geometry of the universe according to Einstein’s theory will depend on the ratio of the critical mass density of the universe to the actual mass density (called omega). If omega >1 the universe will be a sphere, if omega > 1 the universe will be “saddle shaped” only of omega =1 will the universe be flat].. . Although general relativity allows any value for this ratio, inflation predicts that Ω = 1 within our observable universe to extremely high accuracy. Until recently uncertainties in the measurement of Ω allowed any value in the wide range of 0.1≤ Ω ≥ 2, with many observation seeming to favor Ω =0.3. A new generation of detectors, however has dramatically changed the situation. The latest observations, combining data from the Wilkinson Microwave Anisotropy Probe (WMAP), the Sloan Digital Sky Survey (SDSS), and observations of type Ia supernovae, have measured Ω = 1.012 (+0.018, -.022) (10)- an amazing match between prediction and observation.. .
.. .
The second main prediction of inflation is that the presently observed universe should be remarkably smooth and homogeneous on the largest astronomical scales. This, too, has been measured to extraordinary accuracy during the past decades. Starting in the 1960s, Earth-bound, balloon-borne, and now satellite detectors have measured the cosmic microwave background (CMB) radiation, a thermal bath of photons that fills the sky. .. . After adjusting for the Earth’s motion, CMB photons measured from any direction in the sky have the same temperature to one part in 10^5 (12).
.. .
A third major prediction of inflationary cosmology is that there should be tiny departures from this strict large-scale smoothness and that these ripples (or “perturbations”) should have a characteristic spectrum. Today these ripples can be seen directly as fluctuations in the CMB. Although the ripples are believed to be responsible for the grandest structures of the universe- galaxies, superclusters, and giant voids- in inflationary models they arise from quantum fluctuations usually important only in atomic scales or smaller.. . Cosmologists parameterize the spectrum of primordial perturbations by a spectral index, ns. A scale-invariant spectrum would have ns = 1.00; inflationary models generically predict ns = 1 to within `10%. The latest measurements of these perturbations by WMAP and SDSS reveal ns = 0.977 (+0.039, -.025) (10).

No! Dark matter does not equal ether. Ether was designated as the medium through which light waves/photons travelled. It was all wrong because no such medium exists.
