It seems that there really is nothing new under the Sun. A question in the religion forum got me to thinking about gravity and why it is only attractive, unlike electro-magnetism. Nature seems to like symmetry. I then thought, why couldn't there be a repulsive counterpart to gravity and where might we find it? Thinking on it further, it occurred to me that if matter generates gravity, it might be possible that anti-matter generates anti-gravity. The idea is that matter attracts other matter, anti-matter attracts anti-matter but matter and anti-matter repel each other. Sure enough, after doing a quick google search, others have already had a similar idea:

There would be implications for dark matter and dark energy if such a conjecture had any validity. If normal matter compresses space then perhaps anti-matter expands space and this might be the explanation for dark energy. The problem is that this would require a lot of anti-matter in the universe. It's lack of interaction with normal matter could be explained by the repulsive effect but there would still be a difficulty with its distribution. Why didn't it clump together like normal matter? Perhaps its space expanding properties prevented clumping so that all we have is anti-hydrogen distributed relatively evenly throughout space (away from galaxies)? Another difficulty is that it wouldn't explain the accelerating rate of expansion of space.

As for dark matter, this conjecture might do away it since the missing mass could be explained by lots of anti-matter in inter-galactic space. What about the anomaly with the rotation of galaxies I hear people ask? Yes, there are some big unanswered questions although the article above tries to address this in a way I don't fully understand.

Any thoughts?

Empty space is just unattached ethons. Matter is just ethons in rotation around a no spin ethons. Suns create matter by pushing ethons together which stops them spinning. Matter is destroyed in the centre of galaxies in large black holes and ejects ethons at 90 degrees both north and south to the galactic plane. This ejected material recombines into new galaxies at a distance of 300 million light years.

The universe is observed to be expanding at an accelerating rate. If only gravity were at work, it could be expanding but not be accelerating. Dark matter is therefore postulated to have a repulsive force that overcomes gravity at large distances. As far as I know, the dark matter force is claimed to be independent of gravity, and not negative gravity or anti-matter gravity. It's another fundamental force in the universe.
