Large Scale Universe Essay Example for Free

Large Scale Universe EssayCosmology, as defined by Encarta Dictionary is the philosophical study of the nature of the human beings. This concern with viewing the universe and its vast issues and meaning takes the pass into a mysterious spectrum. The very foundation of Cosmology began with Astronomer Edwin Hubble in 1929. He discovered that airer(a) galaxies existed in the universe and determined that these galaxies were moving away from to each one other at a valuate that was constant with the distance between them. The farther away from Earth the wandflower was, the faster they would be travelling away from us. In realizableness, this also proved that universe was expanding.This discovery assisted the profound astronomer with formulating Hubbles Law, which directly contri only whened to giving astronomers the keys to discovering how old our universe is and proving that the universe is expanding. The bigger Bang theory is the most celebrated theory about the creatio n of our universe, which happened more than 14 billion years ago. The process began to expand from particles released from the sea captain explosion and dropping temperatures. The process started as a small speck of result and formed into a dense object as large as Earth from radiant energy and exotic particles called quarks or antiquarks.As the temperature dropped during this process, things such as protons and neutrons began to form together creating helium nuclei over a period of a few hundred thousand years. More than two billion years after the Big Bang, galaxies began to form as gravity started to collect and mass together irregular progeny forming a sponge image structure. Our galaxy, the Milky Way, forms one billion years after this mark. Star clusters form from inside a lusus naturae sphere of gas and spiral arms take shape as settling gas forms into a disk shape displaying a centered core like formation.One example scientist conducted to prove the Big Bang Theory were scientist Arno Penzias and Robert Wilson, who discovered cosmic microwave radiation in 1965 from the Holmdel antenna in freshly Jersey. They discovered that residue left over from the Big Bang explosion was forming low-level radiation pockets end-to-end the universe. This discovery along with Hubbles Law stating that galaxies were traveling away from us, builds a sturdy case in defy of the big bang theory. The Milky Way galaxy is only one out of billions of galaxies floating throughout this vast space.It is flat in shape with a central bulge spiral shaped galaxy that carries more than 100 billion stars and is 100,000 light years in diameter. According to the Cosmic Perspective, If dark national is indeed the most common form of massing galaxies, it must have provided most of the gravitational attraction creditworthy for creating the protogalactic clouds. The hydrogen and helium gas in the protogalactic clouds collapsed inward and gave birth to stars, while weakly interacting da rk matter remained in the outskirts because of its inability to radiate away orbital energy.According to this model, the luminous matter in each galaxy must still be nestled inside the larger cocoon of dark matter that initiated the galaxys formation, just as observational evidence seems to suggest. Dark energy, discovered in 1998 by a team of three Astronomers, Saul Perlmutter, Brian Schmidt and Adam Riess, observed exploding stars to gather numbers for data to accommodate the expanding universe. While attempting to grasp a better understanding of supernovaes, they stumbled across evidence that supported the universe was expanding, but at an accelerated pace.This discovery, in an ongoing effort, changed our view of the expanding universe. Scientist do not know exactly wherefore the universe is expanding at this rate, but dark energy seems to be forcing galaxies and large amounts of matter apart. The destiny of our universe relies on whether gravity can hold this force back from expanding rapidly. However, evidence shows that gravity is growing weaker unconstipated when matter is factored in. This proves that the rapidly expanding universe is not only increasing, but also will not lug increasing. The Theory of Everything stated by Brian Greene, is the theory to end theories.He states, For the first time in the record of physics we therefore have a framework with the capacity to explain every fundamental quality upon which the universe is constructed. For this reason string theory is sometimes described as possibly being the, theory of everything (T. O. E. ) or the ultimate or final theory. These grandiose descriptive terms are meant to signify the deepest possible theory of physicsa theory that underlies all others, one that does not require or yet allow for a deeper explanatory base (Brian Greene, Theory of Everything, October 28, 2003).This theory projects a meaning for everything created in the universe level to the smallest particle all the way up to the largest particle, including all matter and its fundamental principles would be explained down to the deepest explanation at microscopic levels. This final theory would represent an unwavering support of rationality that would unendingly declare that the universe is an absolute intelligent source.
