Universe began with Big Bang from "summary" of A Breif History of Time and the Universe in a Nutshell by Stephen Hawking
In the early 20th century, scientists were puzzled by the behavior of galaxies in the universe. They observed that galaxies were moving away from each other at great speeds, indicating that the universe was expanding. This led to the idea that if the universe is expanding now, then it must have been smaller in the past. The concept of an expanding universe led scientists back in time to the idea of a singularity – a point of infinite density and temperature – from which the universe began. This singularity marked the beginning of time itself. It was an event of such immense energy and heat that the laws of physics, as we know them, break down. This event is what we now call the Big Bang. It was not an explosion in a particular place in space, but rather the sudden appearance and rapid expansion of space itself. The u...
