Expansion does have the appearance of "pushing away". But, as noted, to explain "dark matter", one would observe "anti-gravitational" separations in inert gase

- 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.
