Theories on the Origins of the Universe
By Khoa Nguyen
In the past hundred years, the most important discoveries have not been that on earth, but of that in space. From the Apollo missions to the Lunar landings, man has always tried fruitlessly to uncover the mysteries of the universe. ... The universe is here; it is around us, inside us, it IS us. ...
That said, just what is the Big Bang theory of the origin of the universe? Nature magazine summed it up succinctly by saying: "The explosion from zero volume at zero time of a corpuscle of energy equivalent to the mass and radiation that now constitute the Universe. ... At some point in the history of time, perhaps some ten to twenty billion years ago, all of the matter in the universe was extremely close together. ... Essentially, the universe was curved into itself. ... The singularity at the beginning of the universe was in a condition for which man has no ability of prediction. ...
For an unknown reason, the universe suddenly began to expand. ... It took what scientists believe to be around a billion years for the universe to form into the universe that we see today. ... Hubble had irrefutable proof that the Universe was expanding. ... Known as the red-shift theory, it is on of the major theories that supports the Big Bang theory, proving once and for all that the Big Bang did occur. ... They found the idea of a sudden beginning to the universe philosophically unsatisfactory. Bondi and Gold suggested that in order to understand the universe we needed to make observations of its distant parts, which would of necessity be observations from the past. ... If the state of the universe was different in the past how could we be sure that the laws of physics were not different in the past as well? ... For Bondi and Gold not only would the laws of physics have to be the same in all parts of the universe, but at all times as well.
