The Universe According to Relativity
In the previous chapters, we have already witnessed some of the greatest marvels that Einstein’s Relativity has provided for us. In this chapter, we will describe one marvel that many consider the greatest of all: the power of Relativity to describe the overall structure, evolution and ultimate fate of the entire universe. Can one imagine a more profound, weighty, intellectual achievement? To get us started, we will try to give the reader a real feeling for the basic elements and incredible distances that we deal with in cosmology.
