This seems very plausible as an explanation for dark matter but I'm confused as to whether the author proposes it as an explanation for dark energy as well.
Are there not galaxies on opposite sides of the universe, expanding away from each other too fast for them to ever interact?
- jfengel 7y agoThe case is specifically being made about dark matter, and in particular about the galactic rotation curves that are the primary motivation for the dark matter hypothesis. Dark energy has a completely different basis that wouldn't be subject to this particular alternative hypothesis -- though the very general point of "maybe the approximations we're using are too simple" does still apply. Though really they apply to pretty much any open question.
