Chapter nine of the Fabric if the Cosmos deals with the relationship between temperature and symmetry in our universe. The book states that the universe and cosmos in general has gone through phase transitions similar to those that happen when water turns in to ice. These changes that have happened as our universe gets larger are a result of the decreasing temperature in our universe and also account for a decrease in the symmetry of our universe. One of the most interesting topics of this chapter of the Fabric of the Cosmos was the idea of a graviton- an actual particle that portrays the characteristics if gravity. Is there a connection between gravity’s elusive particle,the graviton, and the unusual and generally weak force exhibited by gravity? I think that there is a definite possibility that there is considering the fact the gravity is the most mysterious of all forces to us.
