What was the Bing Bang? The Big Bang theory was first proposed by Georges Lemaître in 1927, without bearing the name we know it by today, which was only attributed to him in the 1950s.
The common name has contributed to a misrepresentation of the beginning of the Universe, often being described as a massive explosion, similar to an epic supernova. But was our Universe really created in a cosmic fireworks display? Or was there another process at play? What was the Bing Bang?
The “Big Bang” was not an “explosion” in the usual sense at all. It didn’t take place with a puff of shrapnel and fire, and there was certainly no atomic mushroom. The Big Bang theory derives from Albert Einstein’s theory of general relativity and the idea that the Universe expanded from a dense collection of energy called a singularity. There was no actual explosion, but a vast expansion of highly condensed material.

Why, then, is this theory described by such a misleading name? Probably to be ridiculed. Sir Fred Hoyle mockingly referred to the theory as the “Big Bang” with the intention of reducing it to absurdity, and the name stuck. Hoyle believed, contrary to the Big Bang theory, that the Universe itself did not have a beginning, only the components within it came into existence. This is called the steady state theory, which has fallen out of favor with the general acceptance of the Big Bang theory.
If the Universe didn’t explode into existence, where did it all come from? According to the theory, the Universe, which includes all space, time, energy, etc., has been condensed into a zero-volume, extremely hot, infinite-density entity called a singularity. In physics, density is calculated by dividing mass by volume, which means that the equation for determining the density of the singularity involves dividing by zero. If this doesn’t make your brain hurt, the following sure will: since all space and time existed within the singularity, the singularity itself did not exist within space or time, writes Britannica.
The universe as we know it is the result of the expansion and cooling of this singularity. Since the singularity is not in a specific location on the planes of space or time, there is no center of the Universe; everything expands from everything else at an equal rate. As to the origins of the singularity, or even what existed before it, scientists are as puzzled as anyone.
