ABSTRACT


          Black holes are predicted in general relativity as exact solutions of the Einstein field equations. In physical terms, a black hole means a region in the universe where gravity is so strong that nothing can escape. Thus, gravity introduces a new type of randomness or chaos into physics through the loss of information in black holes. The area of a black hole acts as an entropy to measure the loss of information. I will describe black holes as thermodynamical objects with a temperature and entropy. Using the noval arguments in string theory, I will also discuss the microstates of a black hole that are responsible for its entropy and theromodynamical properties.
