Smith 1 Wesley Smith Dr. Cristian Bahrim Modern Physics 3350 Spring 2010 Honors Contract: The Black Hole Phenomenon Stephen Hawking has contributed greatly to what we know about black holes. In addition to this, he collaborated with Roger Penrose to determine that the Universe has been around for a finite period of time, though details of its exact creation remain unidentified. This discussion will primarily focus on black holes as described by Dr. Hawking but will also place a minor emphasis on the origin of the Universe. Black Holes are stars which do not allow light to escape their gravitational field, thereby causing a void of visible light creating what is known as a Black Hole. Hawking’s work on the origin of the universe involves mainly that if the universe is infinite, it disobeys the law of entropy, so then the lifespan of the universe must be finite. These are the two foci of this discussion, and will be discussed in greater detail as following. Modern physics can explain the black hole, which is an object whose mass, M, lies totally within the corresponding schwarzchild radius and is formed by the compression of matter to exceptional densities [4]. Also it explains the beginning of our universe by the theories of relativity proposed by Einstein, which in this case says that there was either a time before time, or a time when time itself did not exist and also is used to describe the non-existence of time inside a black hole. What we know about our universe is constantly changing, as well as the approaches we use to gain information about the stellar evolution phenomena. What we currently know can in some way be attributed to Dr. Stephen Hawking, and therefore this report summarizes some of his ideas and hypotheses.

Smith 2 The theorems, which were proved by Hawking and Penrose in their publication The Nature of Space and Time , showed that there must be a beginning to the universe, however they did not provide much information about how that beginning occurred. These theorems seem to indicate that the universe began in a Big Bang where the universe was first a singularity, and then a massive explosion caused by this singularity collapsing on itself yielded our current universe. This Big Bang was a point where the whole universe and everything in it was scrunched up into this single point with infinite density. According to Dr. Hawking, “One is left with the origin of the universe apparently being beyond the scope of science.” [1] Dr. Hawking’s theories show that science can be used to prove that the universe in fact has a beginning, but they cannot predict how the universe should begin [2]. Dr. Hawking proposes two hypotheses: (1) either the Universe has always existed as it is
