The Big Bang theory is an effort to explain what happened at the very beginning of our universe. Discoveries in astronomy and physics have shown beyond a reasonable doubt that our universe did in fact have a beginning. Prior to that moment there was nothing; during and after that moment there was something: our universe.

Then it would rebound as a white hole. Georges Lemaitre, a Belgian astrophysicist and Catholic priest, came to be known as the "Father of the Big Bang". Lemaitre proposed that the universe began as a single primordial atom of energy, something hot and dense that exploded, causing space to expand outward.In the late 1940s, George Gamow, a Russian-American physicist, conceived of the Big Bang theory as we know it today. La respuesta corta: El Big Bang es cómo los astrónomos explican la forma en que comenzó el universo. Es la idea de que el universo comenzó como un solo punto, luego se expandió y se estiró para crecer tanto como lo es ahora, ¡y todavía se está extendiendo! Saturn is the sixth planet from the Sun and the second-largest planet in our solar system. Like fellow gas giant Jupiter, Saturn is a massive ball made mostly of hydrogen and helium. Saturn is not the only planet to have rings, but none are as spectacular or as complex as Saturn's. Saturn also has dozens of moons. .
