Crossing the finish line in first place, I’m happy†¦until the moment my eyes look up at the clock. It wasn’t enough. My time was just shy of that seventh varsity spot on the Cross Country team. My family comes to congratulate me and I force a smile. They remind me that I’d done my best that day†¦if only my time had been a little bit faster. Next time, I know to focus only on my individual goals and running for my team. Math tests are back today and I have to do well. This can’t be like the last one where I only got a 94%. With that score, I didn’t make it up onto the board where my teacher shows the highest grades. He’s walking towards my pod, handing back tests. He drops my test faced down on my desk. I slowly inch my way towards it until my finger touches the edge.

My score is written in black letters and circled on the top: a 98. I’m happy. I studied hard, I went in for help, and I completed all the homework. My hard work finally paid off. My teacher turns on the SMARTboard and I skim the top scores, searching for my name. One percentage point. That’s all it would’ve taken to get my name on the board.

In chasing perfection, it was difficult for me to accept anything less than perfect. When I did well, I looked to others who obtained higher grades. After being fixated on the fact that nothing was ever good enough, I gradually realized my best is good enough.

Free Essays on Big Bang

We know that our universe exists, however this knowledge alone has not satisfied mankind for further understanding. Throughout time we have asked ourselves, how did our universe begin? How old is our universe? How did matter come to exist?- It seems to be that the questions will always continue to exist. It is important to keep in mind that all of this information is constantly being questioned in order to understand the universe more clearly. What is THE BIG BANG Many once believed that the universe had no beginning or end and was truly infinite. However according to the Big Bang theory, universe is not considered to be, infinite. About 15 billion years ago a tremendous explosion started the expansion of the universe. This explosion is known as the Big Bang. At the point of this event all of the matter and energy was placed at one point. The Big Bang actually consisted of an explosion of space within itself unlike an explosion of a bomb. According to the Big Bang theory the universe is expanding in every direction. Since the Big Bang, the universe has been continuously expanding and there has been more and more distance between clusters of galaxies....

Free Essays on Big Bang Some 12 billion years ago the universe emerged from a hot, dense sea of matter and energy. As the cosmos expanded and cooled, it spawned galaxies, stars, planets and life. Since the beginning of human civilization, people have always questioned the origins of their existence and the creation of the universe. Cosmology, the scientific study of the large scale structure and evolution of the universe, has developed and evolved in response to the human need to know our roots (Silk, Big Bang 1980 456). Within in this field of study, the Big Bang theory has become the most prevalent theory, because the majority of evidence from a variety of different investigations make it extremely likely that something like the Big Bang occurred. The Big Bang theory of cosmology assumes that the universe began from a singular state of infinite density. As Joseph Silk defines the Big Bang theory, it is a model of the universe in which space-time began with an initial singularity and subsequently expands (Silk, Cosmic Enigmas 56). The theory first referenced in Alexander Friedmann's complete solution of Albert Einstein's equations, in 1922. In 1927, George ¡Ã‚ ¦s Lemaitre used equations to devise a cosmological theory that incorporated the concept that the universe has been expanding from an explosive moment of creation. However, the term "Big Bang," as a name for the initial cataclysmic event, was chosen by two men named George Gamow and R.A. Alpher due to their discovery of background radiation, a low-temperature radiation that penetrates the universe at microwave wavelengths (58). Its source is now believed to have been the extremely hot fireball with which the universe began, according to the Big Bang theory. Since its in itial introduction, much evidence has helped to strengthen its case, and other theories have been added to it, such as the Inflationary theory. This theory seeks to account for the physical events, which took place in the very first momen... Free Essays on Big Bang The mystery of the beginning of our universe has puzzled mankind since the dawn of time. This mystery is especially relevant to astronomers, who construct hypotheses called cosmological models to try to find the answer to this ancient question. This paper will focus on two of these models: The Big Bang Theory and The Steady State Model. The Big Bang model postulates that about fifteen to twenty billion years ago, the universe violently exploded. Scientist believe that before the Big Bang, all of the matter and radiation of our present universe was packed together in a primeval fireball. This fireball was in an extremely hot dense state. From this the universe rapidly expanded.1 As this expanding matter cooled, several million years later it condensed into galaxies. The universe has continued to expand, and the galaxies have continued moving away from each other ever since. Today, the universe is still expanding, as astronomers have observed. The Steady State model states that the universe does not evolve or change in time, meaning there was no beginning in the past, nor will there be change in the future. This model assumes the perfect cosmological principle. This principle states that the universe is the same everywhere on the large scale; at all times.2 It maintains the same average density of matter forever. There are observational evidences found that can prove the Big Bang model is more reasonable than the Steady State model including, the redshifts of distant galaxies. Redshift is a Doppler effect which states that if a galaxy is moving away, the spectral line of that galaxy observed will have a shift to the red end. The faster the galaxy moves the more shifts it has. If the galaxy is moving closer, the spectral line will show a blue shift. If the galaxy is not moving, there is no shift at all. However, as astronomers observed, the more distant a galaxy is from Earth, the more redshift it shows on the spectru...
