essay about ufos

Often categorized as monster-like beings with animal instinct qualities and the urge to either destroy the human race or feast on human blood, ufos have taken in a big part of the nation's entertainment business, Alien vs. Predator, Independence Day, Cloverfeild, these are just a few of many films what Hollywood has delivered over the years as its perspective of what UFOs are but Since Ufos are usually described as these monsters, people often categorize Ufos as fantasy or nonexistence, when infect there is scientific evidence that there is extraterrestrial life in the universe.

People who have spotted ufos have described them as disk shape objects normally silver and a few hundred feet in the sky, just floating like a fish in mid air, this phenomenon isn't very new to us. there have been many cavemen painting of men on squared objects looking down at people, how did prehistoric being even have the mentality of thinking of something so complex of their time, unless they truly did see that and recorded it onto their paintings. Many painting and carving of similar form as the one described can be found through many countries like North Africa, Italy, Egypt and countless other countries in different regions and also eras, the most recent claimed sighting was recorded on April 2010. A famous story about a couple who claim to not only witness a ufo, but they claim to have been abducted on one. Betty and Barney Hill were a couple in 1961, they had been Even though people claim to see the same thing all the time they have never caught any physical evidence, besides poor picture and video quality recordings, but even though many people have not seen them, Scientist have been determine to prove otherwise.

Scientist Paul Wrey came up with the anthropic principal in 1940's with a equation to show the possibilities of life on other planets. "N = R F_p N_e F_l F_i F_c L" is the equation and he explains that if "N" was the number of civilizations with we can contact and "R" the rate of star formation, there is about ten starts per year and if "F_p" was the fraction of starts that develop planets and "Ne" was the planets suitable for life, "F1" planets that developed life, "Fc" meant the civilization that could communicate, "L" meant the stage where civilization could process. Scientist have only connects the variables "R,Fp and Ne" the rest of the calculation is still undetermined due to insufficient evidence, because scientist need to find a way to observe how the life process occurs. But Scientists have came up with two hypotheses that can explain the origin of life.

The first one explains how scientists believe that some molecules might be capable to self-reproduce and develop into a combination of different compounds, but based on the calculation this is highly unlikely to happen, because even though some compounds that can be easily made in a lab, have difficulties reproducing on their own, and molecules like RNA who need hundreds of amino acids which are the few of many compounds that cant reproduce, can not be made without amino acids, so the possibilities of this happening is slim. The second hypothesis is the Copernican principle which is best defined as the principle of mediocrity, this principal assumes that we as a world of intelligent beings are nothing special, and that there is an ordinary mechanism that life is developed, but we haven't been able to unveil this mechanism. this hypothesis also believes that if there truly is aliens out there, it is impossible that they will resemble us as a society.
