Gibbsa, Thanks for your comments. As I stated in my initial post this is a "possible" explanation of dark matter, not necessarily the only one. (so your "seed" comments are irrelevant). Obviously it needs to be confirmed by comparing the predicted warping to the actual dark matter observations. And of course that needs to be done around galaxy clusters as well as individual galaxies. It is obvious that the effect will be complex due to the complexity of distribution of mass in space rather than just geometrically perfect halos.
But,of course expanding one side of a continuous space but not the other will lead to a boundary warping. That's simple geometry. Thus it should inevitably have some gravitational effect and that effect should be fairly significant due to the 13.7 billion year history of the Hubble expansion. Time for plenty of warping to have occurred. Edgar On Tuesday, January 21, 2014 9:18:16 AM UTC-5, [email protected] wrote: > > > On Monday, January 20, 2014 4:01:03 PM UTC, Edgar L.
