Accelerating Universe, Cosmological Constant and Dark Energy

Abstract

We present a space-velocity theory of gravitation in a 4-dimensional curved space. The solutions of the field equations yield 3 possibilities for the universe expansion but only the accelerating one is possible. Although the theory has no cosmological constant, we exract from it its equivalent value which is shown to be in agreement with measurements. No pressure is used in the theory.
