Slight caveat: I think we can be quite certain that GR is wrong on some level, but we can also be extremely confident that the way in which it's wrong cannot explain dark matter. Our confidence that the way in which it's wrong doesn't explain dark energy is a little less certain, but it still seems likely that the answer is not a modification of gravity.IcedEcliptic said:I may be miscommunicating in this case; I personally believe that dark matter is composed of WIMPs, or Sterile Neutrinos, or both. I do not believe GR has such holes in it, that we're just "off the mark." Dark energy, I do not know. It seems there is a positive cosmological constant, and vacuum expectation energy would explain both, but it is far from being shown to be. I am disputing your certainty, not your conclusions.
