In this brief review article, the author is going to discuss two of the most intriguing questions that physicists face in the present times, based on two of his previously published articles. Firstly, why our universe is composed entirely of ordinary matter and why there is hardly any free anti-matter that can be observed. Secondly, what the origin is of dark energy. For solving these two problems, he has previously proposed a hypothesized model with at the heart of it a primordial S-particle responsible for the formation of our universe . The S-particle together with its anti-particle counterpart were created immediately following the Big Bang, around 13.8 billion years ago. The S-particle differentiates itself from its counterpart through its course of rotation. The angular rotation of the anti-particle, in accordance with space-time rotation, together with the counter rotation of the S-particle, resulted in a time difference in the formation processes of both our universe and its dual counterpart (formed by the anti-particles). This led to a large distance between the spatial locations occupied by both universes (our universe and its counterpart) in the same space-time continuum.
