1. The basics of the theory are fairly simple. In short, the Big Bang hypothesis states that all of the current and past matter in the Universe came into existence at the same time, roughly 13.8 billion years ago. At this time, all matter was compacted into a very small ball with infinite density and intense heat called a Singularity. Suddenly, the Singularity began expanding, and the universe as we know it began.
2. Two major scientific discoveries provide strong support for the Big Bang theory: • Hubble's discovery in the 1920s of a relationship between a galaxy's distance from Earth and its speed; and the discovery in the 1960s of cosmic microwave background radiation. Based upon Hubble, Einstein, and De Sitter’s works, an astronomer and Catholic priest by the name of Georges Lemaitre proposed in 1927 an expanding model for the Universe. In a sense, he directly contributed to the creation of the Big Bang theory. Though Lemaitre and Hubble are the most credited for the theory, they weren’t the ones to name it. The naming of the Big Bang theory happened randomly during a radio broadcast in 1949 when astronomer Fred Hoyle, creator of the Steady State theory, referred to Lemaitre’s theory as the “big bang idea.”
Though we have an understanding of how the Universe began, we don’t know its exact shape.
Our world seems to have no center or perhaps even edges.
