Big cathexis Theory We certainly know that our initiation exists, however, this knowledge al atomic number 53 has not satisfied mankinds quest for further understanding. Our marvel has led us to question our put in this worldly concern and furthermore, the place of the universe itself. Throughout quantify we have asked ourselves these questions How did our universe begin? How emeritus is our universe? How did matter come to exist? Obviously, these atomic number 18 not wide questions and throughout our brief history on this planet much time and effort has been spent looking for some clue. Yet, later on all this push button has been expended, much of what we know is still only speculation. Yet in 1927 a man by the name of Georges Lemaitre from Belgium proposed that the universe began with a bang. He proposed that a primeval atom exploded and that is how the universe formed itself. His proposal came afterward observing the red shift in distant nebulas by astronomers to a mo del of the universe based on relativity. Before I was enrolled in Survey of Astronomy I wasnt sure what to believe. But after sitting through the class I started to realize that all the pieces be starting to fit together like, why the galaxies are increasing in velocity away from us and also explaining the cosmic background radiation. approximately 15 billion years ago a tremendous effusion started the expansion of the universe. This effusion is known as the Big Bang. At the leg of this event all of the matter and energy of space was contained at one point. What existed prior to this event is completely unknown and is a matter of clear speculation. This occurrence was not a conventional explosion but kind of an event filling all of space with all of the particles of the embryonic universe rushing away from each other. The Big Bang actually consisted of an explosion of space within itself unlike an explosion of a bomb were fragments are thrown outward. The galaxies were not al l clumped together, but rather the Big Bang lay the foundations for the universe. Even more recently, NASAs COBE air was able to encounter cosmic microwaves emanating from the outer reaches of the universe. These microwaves were remarkably 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, comminuted fluctuations began to exist due to temperature differences.
