WebbThe big bang occurred roughly 13.8 billion years ago, giving birth to everything in existence today. In the beginning, a singularity contained all matter; at one moment, this singularity exploded outward in a period of cosmic inflation that lasted for only a fraction of a second but propelled matter at the speed of light in every direction.

Webb20 mars 2014 · The original Big Bang theory was really a theory of the aftermath of the bang. The universe was already hot and dense, and already expanding at a fantastic rate. The theory described how the universe was cooled by the expansion, and how the expansion was slowed by the attractive force of gravity. WebbThe Big Bang event is a physical theory that describes how the universe expanded from an initial state of high density and temperature.
