In a paper about to be published in Nature,
http://arxiv.org/PS_cache/arxiv/pdf/0904/0904.4649v1.pdf , Revnivtsev
et al have definitively demonstrated that the "diffuse" galactic X-ray
ridge is produced by discrete stellar-mass objects.
The authors speculate that the discrete sources, which have X-ray
luminosities in the 10^29 - 10^30 erg/sec range, may be accreting
white dwarf stars or coronally active stars.
Another possibility was predicted in 1987 [Oldershaw, R.L.,
Astrophysical Journal, 322, 34-36, 1987]. Discrete Scale Relativity
predicted that the galactic dark matter is primarily in the form of
Kerr-Newman black holes with masses of either 0.145 solar masses or
0.58 solar masses.
It was predicted in the ApJ paper that the members of this population
that reside in the galactic disk would emit accretion-generated X-rays
at luminosities of about 10^29 erg/sec to 10^30 erg/sec.
Is there a way to decide whether the discrete galactic X-ray ridge
sources are the more conventional accreting white dwarfs/coronally
active stars, or whether this population is comprised of the more
unconventional population of Kerr-Newman black holes? Happily there is
a definitive test. White dwarfs and coronally active stars would not
be expected to generate much Gamma-ray radiation, but the Kerr-Newman
population would. Possibly the Fermi Gamma-ray telescope has the
capability to sort this out. If the discrete galactic ridge X-ray
sources are Gamma-ray emitters, then a new and almost completely
unexpected stellar population will be revealed
The proposed Kerr-Newman black hole population should be even more
abundant in the galactic halo, where their accretion-generated X-ray
luminosities were predicted to be more in the 10^26 erg/sec to 10^27
erg/sec range. A fairly isotropic high latitude Gamma-ray emission
from the galactic halo might be a signature of the predicted
population of black holes.
The Kerr-Newman Black holes would also offer an empirically consistent
explanation for the MACHO microlensing results, and they offer a
viable candidate for the enigmatic galactic dark matter that has
eluded explanation for so long.

[quote:748c568b7b]Let me rephrase this. Discrete Scale Relativity makes a falsifiable

right?- Hide quoted text -
[/quote:748c568b7b]
Discrete Scale Relativity unequivocally, uniquely and definitively
predicts that the galactic dark matter is primarily composed of Kerr-
Newman objects in three populations with highly discrete mass ranges:
8 x 10^-5 solar masses, 0.145 solar masses and 0.580 solar masses. It
is the ONLY theory to make such a prediction.
The halo of the galaxy is the best place to test the Standard
paradigm, which is committed to unspecified particle-mass dark matter
and Discrete Scale Relativity, which is committed to stellar-mass
ultracompact oblects with very well-specified properties.
If Discrete Scale Relativity is the correct paradigm, and only one of
the two paradigms can be correct, then the galactic disk will contain
sizeable populations of the Kerr-Newman ultracompacts.
I cannot know how many of the 473 discrete X-ray objects identified
by
Revnivtsev et al are the putative Kerr-Newman ultracompacts, so this
is a poor choice of falsification tests, if one is looking for a
convincing and unbiased falsification test. The point is that
Discrete
Scale Relativity predicted discrete stellar-mass X-ray emitters,
predicted that their luminosities would be in the 10^29 to 10^30 erg/
sec range for galactic disk sources, and offers this as a candidate
for what Revnivtsev et al found. It is possible that the Kerr-Newman
population is the much larger population of X-ray emitters with
lower
luminosities [=< 10^29 erg/sec] that must underly the observed
discrete sources at 10^30 erg/sec. Hopefully the Gamma-ray properties
of various populations will offer some guidance.
If you, like me, want a definitive falsification test of Discrete
Scale Relativity, then you will have to wait for a definitive
identification of the galactic dark matter. When that happens, one of
the two paradigms will be shown to be right, and more importantly,
the
other paradigm will be shown to be dramatically wrong.
Hope that helps,
