Rather, they think there could be an issue with general relativity and Einstein\u2019s theory of gravity and how it works on the scale of the observable universe. Within this explanation, scientists think that it\u2019s possible to modify our understanding of gravity in a way that explains observations of the universe made without the need for dark energy. Einstein actually proposed such an idea in 1919 called unimodular gravity, a modified version of general relativity that scientists today think wouldn\u2019t require dark energy to make sense of the universe.<\/p>\n<p>Dark energy is one of the great mysteries of the universe. For decades, scientists have theorized about our expanding universe.
