On the galactic scale, my hunch is that the sorting dynamic would be very strong, and you would basically have g+ and g- galaxies. Which would be very interesting, but doesn't solve the dark matter issue.
I think that this would also create a lot of other complex behavior that we don't see. For example, I think we would expect to see many cases of two galaxies or even two galaxy clusters pushing away from each other, because one is g+ and the other g-.
- thyrsus 9y agoExpansion does have the appearance of "pushing away". But, as noted, to explain "dark matter", one would observe "anti-gravitational" separations in inert gases at local scale, which has never been reported.
- dwaltrip 9y agoAh yeah nice idea. However, the expansion we see is stronger when things are farther away. Gravity gets weaker at a quadratic rate as distance increases, so I don't think opposite gravity signs could be contributing significantly to the observed expansion.
