What is Dark Matter? In astrophysics and physical cosmology is called dark matter to hypothetical matter, which does not emit enough electromagnetic radiation to be detected with the current technical means, but whose existence can be inferred from the effects gravitational it causes in visible matter, as well as in the anisotropies of the cosmic microwave background present in the universe. This work responds to each of the known characteristics of dark matter, based on matter and physics known. To respond to the dark matter, we must first understand how originated the matter in the universe, the explanation most accepted is the known as the big bang, this explains that the entire universe and matter come from a singularity infinitely dense and mathematically paradoxical, when you questions that is a singularity infinitely dense, the answer for singularity, is a place where the laws of nature (physics, chemistry and mathematics) do not exist or are not valid, then questions t...
