Today, the consensus among scientists, astronomers and cosmologists is that the Universe as we know it was created in a massive explosion that not only created the majority of matter, but the physical laws that govern our ever-expanding cosmos. This is known as The Big Bang Theory.
Cosmogenesis redirects here. For the Obscura album, see Cosmogenesis (album). The Big Bang theory, which states that the universe expanded from and was a singularity whose radius was zero, is widely accepted by physicists. Cosmogony (or cosmogeny) is any model concerning the origin of either the cosmos or universe. Developing a complete theoretical model has implications in both the philosophy of science and epistemology.
