What Is the Big Bang

Mankind has attempted to explain the creation of the world as we know it with numerous ideas ranging from the Aboriginal people's Dreaming to Christian's belief of the five day creation. However it has only relatively recently that technology has enabled us to form scientifically proven ideas such as the big bang theory. The big bang theory's popularity is due to the overwhelming amount of evidence, such as the Hubble's discovery of the redshift suggesting the distancing of galaxies. Furthermore the presence of cosmic background radiation and the greater understanding of nuclear physics also signifies the big bang theory could be true.

The Big Bang cosmological model states that approximately about 13 billion years ago, the universe rapidly emerged into existence, in an event now called the Big Bang. Prior to the Big Bang, nothing is known of what, where and how it existed, if any thing existed at all. The universe was a collection of the matter and radiation both indistinguishable in dense plasma state billions of billions degrees Celsius all condensed into an area smaller then a size of an atom. The Big Bang states that between 10-33 and 10-32 seconds after the Big Bang, driven apart by an antigravity like antimatter, the universe expanded faster then the speed of light, possibly increasing from being the size of an atom to the size of a galaxy in a fraction of a second. Still less then a thousandth of a second later it had cooled enough for particles such as quarks, neutrons and protons to form, as well as the anti particles arising in constant annihilation of matter, where only one in a billion quarks were spared. Matter consisting of electron and proton bonds were destroyed by the electromagnetic force carried by photon, resulting in the universe resembling a foggy, murky gas. It wasn’t until the universe cooled and universe expanded, that the photons had lost enough energy to allow electrons and protons to bond and create atoms. These first primitive atoms, mainly comprised of hydrogen and helium were the building blocks, arranged and re-arranged in a stable environment for 13 billion years to create what is the universe today.

The fundamental concept of the Big Bang theory states that the universe is constantly expanding. The first and the most crucial piece of evidence of the Big Bang theory supports the supports the argument that the universe is expanding. arises from the study of the quality of light of distant galaxies. It was Edward Hubble who, trying to map large areas of the universe first observed a phenomenon where light emerging from galaxies further away seemed redder then light from closer galaxies. The color of light is directly correlated to its wavelength, where in the spectrum of white light, red indicates light comprised of longwaves and blue indicates light comprised of shortwaves. The fact that galaxies discovered further and further away in all directions are on the positioned further on red light side of the spectrum suggest their wavelengths have been and still are being stretched, only explained by expansion of the universe. Considering the expansion of the universe, if the process was reversed, the universe would contract to one single point in space and time, what we call the Big Bang.

The extreme conditions, temperatures and amounts of energy, needed to support the Big Bang are phenomenal. The Big Bang theory states that in the first few thousand years the universe was too hot and to energetic for any atoms to form,
