Cosmological Tests of Gravity:
Hence, looking for modifications to GR(广相引力的修正) on large scales is tantamount to looking for the effects of fifth forces in an unscreened regime. This is uncharted territory and one of the few pristine arenas in which we might find evidence for new physics.
Dark Energy Versus Modified Gravity:
Generic modifications lead to new physics on small scales. Indeed, all known modifications to Einstein gravity introduce new degrees of freedom in the gravitational sector. These new particles mediate a fifth force, so the theory must employ some screening mechanism in order to evade local tests of gravity, which are very constraining.
