Before and after the Big Bang: Why does the Universe Expand at an Accelerated Rate, where did Antimatter Go? Problem of “Dark Matter”

Abstract

The observed accelerating expand of our universe can only be explained by the presence of an unknown, dark energy. According to the current idea, the existence of unknown energy is understandable assuming the giant energy concentrate formed before the Big Bang is not the result of the spontaneous fluctuation of the vacuum, but of the fluctuation of unknown energy that originally filled the universe in a homogeneous way.
