  • How Does Alien Life Exist

    universe. Astronomers believe this to be true because they have yet to discover anything in the universe that would indicate the existence of a civilization that would register on the Kardashev scale. The Kardashev scale, named after Russian astronomer Nikolai Kardashev in 1964, is a scale system used to determine the degree of advancement of a civilization based upon its mastery of energy sources in the universe. A Kardashev I civilization would be a civilization that has mastered the use of nuclear and renewable energy sources, such as solar energy or geothermal energy, whereas a Kardashev II civilization has mastery over harnessing the energy generated by entire planets and stars. At the top of the scale is the Kardashev III civilization, which is capable of harnessing the energy of entire galaxies. Astronomers theorize that a civilization capable of such grand technological feats would produce very large amounts of some form of emission such as gases or heat along with many other forms of waste in the process. Therefore, scientists attempt to locate these civilizations by searching for anything that would indicate the use of large amounts of technology that would be required to make use of all of that energy. However, astronomers have found nothing that would indicate the existence of either a Kardashev II or III level civilization. Astronomers look to humanity as the reason why such a civilization has yet to be found. The current theory amongst most scientists estimates…

  • The Pain Scale By Eula Biss Analysis

    The measurements of our world strive to quantify the quality of our lives. The scales we use to measure ourselves and how we feel, fail to understand the concept of life itself. The tears of joy felt by a mother; the symphony of silence held by a survivor; the loudness of a murmur spoken as a prayer. Life is a composition, led by a melody, woven piece by piece, tied by our hopes and colored by our sorrows. Like darkness is the absence of light, pain is measured by the absence of happiness.…
