Samanthe A. Braswell How Thermodynamics is used to Shine Light on the Mysteries of Black Holes This paper discusses the phenomenon of black holes, with an emphasis on the Second of Law of Thermodynamics, which is concerned with entropy within a given system. The first aspect to be discussed is the life and death of a star, which explains the formation of black holes. Secondly, the “non-decreasing property” of the area of a black hole’s event horizon will be examined. Finally, entropy and its implications for the study of black holes will be discussed in length, while incorporating the views of physicists Stephen Hawking and Kip S. Thorne. This exploration of the relation of the second law of thermodynamics to the phenomenon of black holes provides an understanding of how entropy can possibly be used to locate black holes.
