Abstract

Today the space of our universe is filled with invisible stuff matter which expanding under the action of gravity which was dark matter. In 1990’s astronomical observation and theoretical calculation was leading astrophysicists to believe that not only the dark matter but also there is vacuum empty space filled in universe that is dark energy. It is suggested that the apparently disparate cosmological phenomenon attributed to so called “dark matter” and dark energy arise from quantum level of space -time itself. This creation of space time results in metric expansion. A recent modification of Einstein’s theory of general relativity by Chadwick, Hodgkinson and McDonald incorporate space time expansion. Recent evidence predicts that apparent amount of dark matter increases with age of universe. In addition proposal leads to the same result for the small but non-vanishing cosmological constant, related to dark energy.
