The Begining and Ending of The Universe.

Astronomy 1A 9 December 2003 The Beginning and Ending of the cosmea The following essay is well-nigh the beginning and suppressing of the universe. The sources I impart be exploitation ar a The excogitation of the Universe a admit by Timothy Ferris, and the by edition Astronomy word of honor by Chaisson and Mcmillan. in that respect be many theories of how the universe all began and how it will end. I will be emphasizing on the k nowledgeability and exploitation of the universe. I will be referring to the speculation more or less widely used: The Big crawl in theory. This theory basically states that e genuinelything in the universe was at a single office, that point exploded, sending parts and debris e reallywhere at very high speeds, which evolved into the universe. This all happened somewhere among 9 and 14 billion eld ago. The age of a critical-density universe with no cosmological constant is about 9 billion years old. The universe was composed entire ly of radioactivity when it all began. beam of light ultimately produced everything we see or so us. The earliest known season that can be draw by modern physics is called Plancks time. This time is 10-43 seconds. We do non know what happened before Plancks time because we lack a theory. We need a quantum theory of gravity. GUTs are the Grand Unified Theories, which are theories that express the actions of the single cart that results from combining of the strong, weak, and electromagnetic forces. In the beginning there was 1 force, supergravity. There are now 4 forces in nature. 2 10-34 seconds afterward the Big Bang the temperature was 1028 kelvins. For a moment the universe entered a very strange, and unsettled high-energy state. Temporarily empty pose gained massive pressure, which momently overpowered the pull of gravity. This caused the universe to expand very rapidly...

This essay was very entropy for its purpose. The writing style is estimate and suites the subject you presented. The intro shouldve mentioned the concepts exhibited throughout the essay, instead of going neat into theories. However, I do like how it was presented in sections, which adds to the fluidity and helps mince down the complex concepts discussed. The conclusion was rather disappointing, and you only presently mention the end of the universe. This is a definite negative, since the title may prove to be misleading. Overall, you did an adequate job at presenting the information pertaining to the beginning of the universe, although it is quite a lacking in respect to the end.
