Big Bang

Big Bang

the speed of light = 299 792 458 m / s (http://www.google.hn/#hl=es&source=hp&q=the+speed+of+light&aq=f&aqi=g1&aql=&oq=&gs_rfai=&fp=edb4ab2ede0782d5). As fast as light may be, the light from say, a star may travel many years to get to Earth. Which is why, when we sit and observe the stars we may wonder if we are looking at a star that actually exists or if we are looking at merely the light of a star that existed many many years ago. We could not have come to this realization just by simply looking at something. To come up with these ideas and reflections we must ruly observe and question something. Ideas like these are taught in the novel "Sophie'd World" by Jostein Gaardner. For example when Alberto tells Sophie "Being interested in why we are here is not a "casual" interest like collecting stamps. People who ask such questions are taking part in the debate that has gone on as loing as man has lived on this planet. How the universe, the earth, and life came into being is bigger and moe important than the question who won the most gold medals in the last Olympics." (Gaardner 14) In the begining of the book Alberto is first beginning to teach Sophie to think in a way that she questions everyhting so that she can finally can question and make her own conlusions of why we are here and how. At the end of the book in the chapter titled "The Big Bang" hilde also starts questioning the universe and existence. "It's a strange thought that we live only on a tiny planet in the universe." (Gaardner 498) This chapter connects to the rest of the book because The Big Bang offers an explanation of how everything started. "The Big Bang theory is an effort to explain what happened at the very beginning of our universe. Discoveries in astronomy and physics have shown beyond a reasonable doubt that our universe did in fact have a beginning. Prior to that moment there was nothing; during and after that moment there was something: our universe. The big bang theory is an effort to explain what happened during and after that moment."(http://www.big-bang-theory.com/)
