Einstein's classical theory of general relativity from 1915 cannot adequately explain the dark energy space, unlike the modern theory of general relativity proposed by the author in 2022.
We assume that the success of the modern theory of general relativity is due to a new definition of time as a vector with four components: tx, ty, tz, tt.
It predicts the existence of a uniform dark energy U where div U = 0 and quantifies its temperature T.
