Dear John,
It is instructive to look at the reasons why all this phantom
matter/energy was postulated to exist in the first place! IIRC, it started
when it was noticed that the radial (?) momentum distribution of galaxies
did not follow the predictions of a gravity only model.
Dear Stephen,
thanks for the considerate reply and the basic consent. The facts you
mentioned are indeed well known and at their onset I was also enthused
(I am old enough for that) when I rethought all the gravitational
discrepancies (galaxies would fall apart etc.) at that time.
That was then,
