What is the Big Bang Theory? Well, it's more of a half-constructed theory to give atheists something to believe. So why believe it? We believe this because the science education system is constantly evolving and really shouldn't be taught in schools, but scientists create the curriculum for science lessons instead. Nothing solid actually. But this is going astray. Let's talk about the Big Bang! Say no to plagiarism. Get a tailor-made essay on "Why Violent Video Games Shouldn't Be Banned"?

During that time, the entire Universe was inside a bubble thousands of times smaller than a pinhead, and it was insanely hot and dense. Out of nowhere this little bubble started to expand. This expansion created what we know as the Universe. In such a short time the Universe went from the size of an atom to the enormous, ever-growing galaxy we have today. According to the Big Bang theory, the universe appeared as a singularity. Singularities are believed to exist at the centers of black holes. These zones of infinite density are called “singularities”. Our universe is thought to have started out extremely small, infinitely hot, and infinitely dense. The more time, the more content. This observation demonstrates that each galaxy took the same amount of time to move from its initial position to its current position. This observation is called “Hubble's Law,” after Edwin Hubble (1889-1953) who discovered it in 1929. Edwin Hubble's evidence supports the expansion of the universe and suggests that the universe was once compact. Third, if the universe was as insanely hot as the Big Bang suggests, scientists should be able to find some of this remaining heat. In 1965, scientists made use of the cosmic microwave background radiation that permeates the observable universe. Finally, the discovery of large quantities of helium and hydrogen led to support for the Big Bang theory. Please note: this is just an example. Get a custom paper from our expert writers now.

In the fractions of the first second after initial creation, what was once void began to expand into the universe. Immediately after the Big Bang, the universe was tremendously hot like an open fire, due to the movement of matter and antimatter in all directions. (For each type of matter particle, there is also a corresponding antimatter particle. Antimatter particles look and behave just like the corresponding matter particles, except they have opposite charges.) When it began to cool there was an equal abundance of matter and antimatter. . However, antimatter disappeared and is rarely found today, leaving only matter to fill it.
