If we use the Friedmann-Lemaitre-Robertson-Walker model for a vacuum dominated universe, we see that time may be a function of a length, the so called co-moving distance. In the FLRW model, this function is injective, so for each time t there is one co moving distance a(t). Straightforwardly, we can assume that time has the dimension of a length, even if, in a fourdimensional universe, the four dimensions are not isotropic. Taking account of this hypothesis, we can solve the EPR paradox for entangled states. Moreover, a simple model of antimatter can also be made: antimatter deforms the universe inwards while matter deforms the universe outwards. Dark matter is also deduced to be a track of massive moving objects within the local curvature of the universe. And finally, taking account that our universe is fourdimensional and that time may be the fourth dimension and has the dimension of a length, the mystery of dark energy is solved. Indeed, in a fourdimensional universe, what we call dark energy has a positive pressure which comes naturally from the expansion of the universe.
