We live in a determinate expanding universe that has not existed forever and that all matter, energy and space in the universe was once compressed into an infinitesimally small volume, which exploded in a cataclysm " Most scientists today believe that the Big Bang became known as the Big Bang. Furthermore, the Big Bang is a rapid expansion of matter from a state of enormously high density and temperature which, according to current cosmological theories, marked the origin of the universe. The phrase is coined by Fred Hoyle during a radio broadcast in 1949. Say no to plagiarism Get a custom essay on "Why Violent Video Games Shouldn't Be Banned"? , "explosion" is just an often used analogy and is slightly misleading as it conveys the image that the Big Bang was somehow triggered at some particular center, however, the same pattern of expansion would be observed by any part of the universe, so there is no particular location in our current universe that can claim to be the origin. The Big Bang is usually believed to be a theory of the birth of the universe, although it does not technically accurately describe the origin of the universe. Nor does it try to explain what started the creation of the universe, or what happened before the Big Bang, or even what lies outside the universe. All this is normally considered to be outside the scope of physics, and more of the interest of philosophy. . Since time and space as we understand them began with the Big Bang, the phase “before the Big Bang” is as meaningless as “north of the North Pole.” Therefore, to those who argue that the idea of ​​a Big Bang violates the First Law of Thermodynamics, also known as the Law of Conservation of Energy, which states that matter and energy cannot be created or destroyed, supporters respond that the Big Bang does not address the creation of the universe, only its evolution, and this, since the laws of science break down anyway as we approach the creation of the universe and there is no reason to believe that the First Law of Thermodynamics would apply. The Big Bang theory is the model that describes how the universe expanded from a state of very high density and high temperature and offers a complete explanation for a wide range of phenomena that include the abundance of light elements, the cosmic background microwave radiation (CMB), Hubble's law and large-scale structure.
