The Cosmos: Creation :: essays research papers

The Cosmos CreationWhere is the creation from? Where is it going? How is it put together?How did it get to be this way.These are Big questions. Very easy to affect but almost impossible to answer.We want answers for philosophical reason having nothing to do with science. Noone will get rich from discovering the structure of the universe unless theyright a book virtually it.The area of science dealing with Big questions is called cosmology. Thereason for its study is found in the fact thatThe universe was born(p) at a specific time in the past and has expanded eversince.The Expansion of the UniverseEdwin Hubble established the existence of other galaxies. He famous that thelight from these galaxies was disruptioned toward the red. That is its wavelengthwas longer than that of the light emitted from the corresponding atoms in thelab. Furthermore he found that the farther away the galaxy was the more it wasshifted toward the red end of the spectrum. Hubble attributed this shift t o thedoppler effect.Hubble saw this and concluded that all galaxies are rushing away from us andthe universe is expanding as a whole. Modern equipment has observed andverified this so-called Hubble amplification exists throughout the observableuniverse.This shows three important things. First in that respect is no significance to thefact that earth seems to be the center of the universal magnification. In everygalaxy it would look as if you were standing still and all others were rushingaway from you. Second the movement of the universe is not like an explosion.Galaxies are not moved through the universe but expand with the universe. Thirdthe galaxies themselves do not expand only the space between them.Finally if you ask where the expansion started the only answer is everywhere.In the words of the fifteenth-century philosopher Nicholas of Cusa, "theuniverse has its center everywhere and its edge nowhere."This theory has one fact that is inescapable. The universe was not alwaysthere but did have an beginning. This has come to be known as the Big-Bangtheory.Universal FreezingWhen the universe was younger it was smaller. When matter and energy arecompacted the temperature inevitably rises. thence when the universe was youngerit was hotter. We can see six crucial events called "freezings" where thefabric of the universe changed in a fundamental way.The most recent occurred when the universe was about 500,000 years old,about 14,999,500,000 years ago. After 500,000 years permanent atoms started toform. Before 500,000 years matter existed as loose electrons and nuclei in a
