big bang theory :: essays research papers

Big sack out Theory We certainly know that our universe exists, however, this knowledge alone has non satisfied mankinds quest for further understanding. Our curiosity has led us to drumhead our place in this universe and further more(prenominal), the place of the universe itself. Throughout duration we have asked ourselves these questions How did our universe begin? How old is our universe? How did government issue go to exist? Obviously, these are not simple questions and throughout our brief account on this planet much time and effort has been spent sounding for some clue. Yet, after tot in ally this energy has been expended, much of what we know is unperturbed only speculation. Yet in 1927 a man by the do of Georges Lemaitre from Belgium proposed that the universe began with a bang. He proposed that a primeval atom blow up and that is how the universe formed itself. His proposal came after observing the red slip of paper in distant nebulas by astronomers to a model o f the universe base on relativity. Before I was enrolled in Survey of Astronomy I wasnt sure what to believe. But after sitting through the severalise I started to realize that all the pieces are starting to fit unneurotic like, why the galaxies are increasing in velocity away from us and also explaining the cosmic background radiation. About 15 billion historic period ago a tremendous explosion started the expansion of the universe. This explosion is cognise as the Big Bang. At the point of this event all of the matter and energy of space was contained at one point. What existed prior to this event is all in all unknown and is a matter of pure speculation. This occurrence was not a conventional explosion but rather an event filling all of space with all of the particles of the embryonic universe rushing away from separately other. The Big Bang actually consisted of an explosion of space within itself inappropriate an explosion of a bomb were fragments are thrown outward. The galaxies were not all clumped together, but rather the Big Bang lay the foundations for the universe. Even more recently, NASAs COBE satellite was able to detect cosmic microwaves emanating from the outer reaches of the universe. These microwaves were unco uniform which illustrated the beginning of the early stages of the universe. However, the satellite also discovered that as the universe began to cool and was still expanding, small fluctuations began to exist due to temperature differences.
