The Origin of The Universe

We live in a determinate expanding universe which has not existed forever, and that all the matter, energy and space in the universe was once squeezed into an infinitesimally small volume, which erupted in a cataclysmic “explosion” which has become known as the Big Bang are believe by most of scientists now Furthermore,Big Bang is a quick 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 1949 radio broadcast .

In reality, “explosion” is really just an often-used analogy and is marginally misleading in that it conveys the image that the Big Bang was triggered in some way at some particular centre. In fact, however, the same pattern of expansion would be observed from anywhere in the universe, so there is no particular location in our present universe which could claim to be the origin.The Big Bang is usually deliberated to be a theory of the birth of the universe, although technically it does not precisely describe the origin of the universe. Neither does it try to explain what initiated the creation of the universe, or what came before the Big Bang, or even what lies outside the universe.

All of this is normally considered to be outside the remit of physics, and more the concern of philosophy. Given that time and space as we understand it began with the Big Bang, the phase “before the Big Bang” is as meaningless as “north of the North Pole”. Therefore, to those who claim that the idea of a Big Bang violates the First Law of Thermodynamics which also known as the Law of Conservation of Energy ,state that matter and energy cannot be created or destroyed, proponents respond that the Big Bang does not address the creation of the universe, only its evolution, and that, as 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 describes how the universe expanded from a very high-density and high-temperature state,and offers a comprehensive explanation for a broad range of phenomena which including the abundance of light elements, the cosmic microwave background (CMB), Hubble’s law and large scale structure.

According to the standard theory, our universe sprang into existence as “singularity” around 13.7 billion years ago. “Singularity”a point or region of infinite mass density at which space and time are infinitely distorted by gravitational forces and which is held to be the final state of matter falling into a black hole.
