The Creation of the Universe

The Big Bang Theory is believed to be the most probable and reasonable explanation to how the universe was created, is a widely discussed topic among cosmologists and astrophysicists. The Big Bang theory is about an event that explains the origins of the universe. It relates heavily to the sciences of cosmology and astrophysics. It is a widely accepted theory among people all across the world, and is also a widely discussed topic that has not been entirely explained yet. Many are still left wondering and searching for a scientific explanation as to how the universe was created, when it was created, and why certain things work the way they do. In the beginning there was nothing, until came a dense fireball. This so-called fireball exploded which created the universe. The explosion was the biggest blast in the history of the universe as well as the creation of it. In only a second, gravity was created and the universe began to expand rapidly. The universe never sits still. It expands at a gradual rate. In the 1920s, Albert Einstein, an astrophysicist from Germany, had discovered evidence of the expansion of the universe through his Theory of Relativity, which was published in 1915. Following the creation of gravity, subatomic particles, such as protons and neutrons, were formed due to the force of the particles colliding with each other. It was actually around three minutes later that protons and neutrons came into existence. “Three minutes later, when the temperature was a mere 500,000,000 degrees Fahrenheit (277,777,760 degrees Celsius), protons and neutrons formed atomic nuclei” (“Big Bang Theory”). According to most scientists and theorists, the universe began 13.7 billion years ago. The Big Bang was the phenomena that created the universe. Exactly why the universe started as a fireball and why it exploded is unknown, but a few theories in generality of the Big Bang are plausible. The Big Bang obviously occurred in the universe, or rather
