That's true, the cosmological constant might be based on some phenomenon we haven't thought of yet. My main point was just that you don't need new physics to explain the fact that galaxies are flying apart alone (without the additional fact of acceleration), since this can be explained just using general relativity without a cosmological constant.TR345 said:Even if the cosmological constant can be used to predict an accelerating universe, that doesn't explain why there is a cosmological constant. So some new weird effect could be at the root couldn't it.
