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.
The Big Bang is a scientific theory about how the universe started, and then made the groups of stars (called galaxies) we see today. The universe began as very hot, small, and dense, with no stars, atoms, form, or structure (called a  singularity ).he Big Bang is a scientific theory about how the universe started, and then made the groups of stars (called galaxies) we see today.
