Have you ever wondered how the universe was created? Or how it came to be the seemingly infinite place it is today? Myself and many others are intrigued by this same concept, known as the Big Bang Theory. The Big Bang Theory was a dominant scientific theory that revolved around the knowledge of the origin of the Universe. Astronomers, scientists and cosmologists believe that the Universe we know today was created when a massive explosion came about, that not only created the majority of matter, but the physical laws that govern our non-stop expansion of cosmos. In 1927, a Belgian catholic priest named Georges Lemaître based his theory off the work of Einstein’s Theory of Relativity. Lemaître noted that an expanding universe could be traced back in time to a single, originating point. Georges Lemaître’s theory of an expanding Universe was confirmed by Edwin Hubble 2 years later, in 1929. Hubble theorized that all outlying clusters and galaxies are retreating away from our vantage point with an apparent velocity proportional to their distance. This meaning that the farther they are, the quicker they move away from us, no matter what the direction. After the initial expansion, the scientists theory sustains that the Universe cooled adequately to allow the development of subatomic particles, and later atoms. Huge clouds of these primordial elements later fused through gravity to construct galaxies and stars.
Roughly 13.8 billion years ago all of the present and past matter in the Universe began to exist. Around this time, all matter was coagulated into a tiny ball with severe heat and a never-ending density familiarized as a Singularity. As the Singularity started to expand, the Universe itself then began.
