The Universe s Origin Centers On A Cosmic Catastrophe
The theory of the universe s origin centers on a cosmic catastrophe known as the big bang. The big bang theory proponents imply that 10 billion to 20 billion years ago, a massive blast from an ancient and unknown type of energy allowed all the universe s known matter and energy, including space and time. The big bang theory was first suggested in the 1920 s by a Belgian priest named Georges Lemaà ®tre. He theorized that the universe began from a single primordial atom. The idea received major reinforcements by Edwin Hubble s observations that other galaxies are moving away from our own at great speed, in all directions, as if they had all been propelled by an ancient explosive force, (National Geographic, n.d.). Scientists are not certain how the universe evolved after the big bang. Many believe that as time passed and matter cooled, more diverse kinds of atoms began to form, and they eventually condensed into the stars and galaxies of our present universe, (Borner, 1993). Planets may have formed as a result of a supernova blast. Planets that existed before the supernova were destroyed. Any planets that had survived the explosion were left behind as free-floating objects. Planets found around pulsars, remnants of the supernova explosion, formed as a result of pre-existing stellar companions. In addition, planets may form in an accretion disk of fallback matter surrounding a pulsar, (Williams, 2014).

Beginning and evolution of the universe A. Scientific view As the universe enlarged, matter started to form into gas clouds, and form there its shaped stars and planets. However, to understand how the universe formed into its present shape, we must understand how galaxies, planets and stars are formed. Then suddenly, the universe began to enlarge at a very fast rate, while slowly cooling down from its initial state of great temperature. When the universe was about 65% of its size, the solarRead MoreA Short History of Nearly Everything6112 Words à |à 25 Pagesused within his school.[2] [edit] Contents Bryson describes graphically and in layperson s terms the size of the universe, and that of atoms and subatomic particles. He then explores the history of geology and biology, and traces life from its first appearance to today s modern humans, placing emphasis on the development of the modern Homo sapiens. Furthermore, he discusses the possibility of the Earth s being struck by a meteor, and reflects on human capabilities of spotting a meteor before itRead MoreFate and Destiny7886 Words à |à 32 Pagesancients saw little or no difference between the terms in their own times. In Latin, the word for fate is fatum and derives from the verb meaning ââ¬Å"to speak.â⬠Bollas (1989) notes that a fatum is a prophecy and that a fatus is an oracle. This definition centers on the fact that most knowledge of oneââ¬â¢s fate came through a verbal statement or riddle. Destiny comes from the Latin word Destinare and means ââ¬Å"to fasten down, secure or make firmâ⬠(Bollas, 1989).

At chapters end, Carson acknowledges that the town is an imaginary one, but lest the tale be dismissed as mere fantasy, she hastens to add that each of the catastrophes it catalogs has actually happened somewhere, and many real communities have already suffered a substantial number of them. Chapters Two and Three Not until chapter two does Carson identify the source of the ills described in chapter one:
