Examples of these are modified [[Newtonian dynamics]], [[entropic gravity]], [[modified gravity]], theories of large-scale variations in the matter density of the universe, [[bimetric gravity]], scale invariance of empty space, and decaying dark matter (DDM). > **See**:: [[physics]] ##### ^dataviews > [!dataview]+ Related unlinked notes > > No results to show for list query. > [!dataview]- Other unlinked mentions > > - [[expanding universe]]
