Cosmology Free Essays and Papers Example
Modern cosmology is a child whose siring is credited to Edwin Hubble, the first person to show that there are other galaxies out there. For centuries, the thought was that what notion mankind had of his universe was the only one present; however, Hubble went on to show that the universe was vast and growing in his 1926 work, ‘the realm of the Nubilae’ (Hubble, P. 236). This finding broadened view of the world that man had thought was his entire universe and also opened new dimensions into our outlook of outer space and the world as it is.
It is from these observations by early man that modern cosmology sprung from. From Aristotle to Ptolemy, to Galileo who was the first man to glimpse into outer space through the aid of an instrument other than the eye, the telescope, modern cosmology has had a lot to learn from the successes and mistakes made by those other theories and concepts that preceded it in that it had a basis to stand upon and theories to prove and disapprove.
The scientific discoveries since the time of Hubble have taken gigantic steps toward recognizing the world as it is, aided by advanced technology that enables scientists to view far off objects and determine their correlation with each other. As Adler (2006) says, the galaxies are like a the beads of a necklace, so many, expanding into a world that man with all his advanced technology has yet to glimpse.
Modern cosmology tries to explain the after effects of the big bang theory, but what exactly is the big bang theory? The big bang theory is what is described as the beginning of the universe. The universe is said to have sprung from a singularity, a form that defies all laws physics and what is harder to explain is where this singularity came from than what it did afterwards. It is believed that other forms of singularities abide in the black holes that are the voids in the galactic system our universe is part of (Hawking and Ellis, p. 25).
The big bang theory is described as the point when the form that came to be the universe started expanding rapidly, filling out, creating space and matter, and without adhering to the laws of physics as they are now, went on to form the universe as we know it today. It is still expanding.
The Milky Way Galaxy Essay
The Milky Way is just but part of the larger collection of galaxies. Its structure, once thought to be spiral has come to be described like an elongated bar that that supports that which has always been known as the spiral milky way. The Milky Way is thought to be composed of over thirty million stars, but dark holes and clouds of dust prevent proper assessment of the Milky Way.
The spiral-look that the Milky Way was thought to have is due to the fact that there are very bright stars at the center of the Milky Way and the light they send off give it a spiral look. Research and discoveries about the universe as it is has always had to come to terms with the spiritual side and powers of man. In that the forces that dictated the universe were attributed to the supernatural powers over the ages and were entrenched in the beliefs of man, modern Cosmology has met its skeptics just like the fore runners of astronomy faced over time.
Modern cosmology is a million miles ahead of early man’s understanding of the universe. It scientifically explains the why and how based on scientific fact as opposed to the spiritual sense man in earlier times tried to explain the beginning of the universe through tales whose beginning eluded his imagination.
Touted as the most massive and expensive experiment in history, researchers in Switzerland drawn from all over the world have created a machine that is going to replicate conditions as they were after the big bang and collide opposing particles at conditions similar to those at the beginning. Critics have already filed lawsuits urging that the experiment be put to a stop with the argument the experiment will create a huge hole that will obliterate the earth and cause massive cosmic interruptions.
In a report by CNN (2010) on the experiment to recreate matter from the particles, the experiment has been dubbed a success. The experiment proves that matter flowed freely after the bang and supports the assumed big bang theory that this is the matter that went on to create what is today’s universe through expansion.
All in all, the cosmos is still remains a mystery, what is observed and passed as fact today might be looked upon tomorrow as false hood tomorrow, as the vast world in the outer space still remains a realm that man is yet to visit and verify the accuracy of his information. Just like modern cosmology did away with the beliefs held by the thinkers of the ancient and past times, greater advances in technology might lead to the changing of what the universe is really al about in the near future, either conform held beliefs or alter them.
