Probability Of Aliens Essay

3031 words - 12 pages

Abstract:This essay evaluates through a multitude of examples the overwhelming probability of extra terrestrial life in our Solar System. By describing the requirements of life as the presence of a liquid, an energy source, and organic molecules the probability of life existing elsewhere in our Solar System can be proven. By analyzing different variations of said requirements and going beyond the scope of Earth's environment, the essay displays the multitude of available locations in our Solar System.The wide sweeping nature of organic molecules is evaluated based on their origin from the Kuiper belt; thus proving that their displacement is over most of the solar system.The requirement for an energy source is further evaluated and alternative solutions are provided. These alternate solutions cancel out the need for a planet to be a certain distance from the sun. For example, the use of friction in Saturn and Jupiter's moon as an alternative heat source. In addition, certain adaptions from species on Earth have proven the ability to survive in extreme conditions.A liquid's presence in a living environment is further widened by the possibility for alternate liquids outside the boundaries of water. In addition, the possibility for life underneath the surface is also proven through Mar's similarity with the Antarctic tundra.In conclusion, this essay will give an over arching evaluation of the possibility of life in our Solar System through examples based on conditions within Earth's environment, but also show what variations may arise on other planets.Table of Contents:Title Page: Page 1Abstract: Page 2Introduction: Page 3Body of Paper: Page 3 to Page 11Conclusion: Page 11Work Sited: Page 12Are We Alone?Research Question: What is the probability of the existence of extra terrestrial life in our solar system?For eons, the human race has been fascinated by what lies beyond the boundaries of our planet. As technology evolved, people became increasingly aware of the vastness of our universe. Then the ultimate question comes to the forefront of every explorer's mind: are we alone? The debate over the existence of extra terrestrial life has gone on for centuries, with strong evidence supporting both sides. However, the new evidence that has emerged leans towards that likelihood that life does exist elsewhere in our solar system. Yet, the problems that plague thousands of scientists is simple - where and when? While the technology of our day is extremely meticulous, it does not yet meet the monumental obstacles imposed by space travel. This has left our world relatively blind to potential life elsewhere. Furthermore, mankind's entire existence is but a speck in the almost 14 billion year life of our universe. (Seti Institute, 2) Therefore, while it may be plausible that life exists elsewhere, it is more plausible that this life has not yet begun or already was. Nonetheless, the following evidence supports the theory that the solar system has multiple life...
