Abstract
General relativity is a subject that has too far-reaching of conclusions about the nature of reality and our universe to be only understood by specialists. If a non-specialist wishes to understand the theory without having to spend months or years studying it, they are often forced to resort to popular science articles that do not provide the theory's full depth and often simplify its details to the point of misrepresentation. In this report, I provide an introduction to general relativity at the undergraduate level that provides more insight into the theory than popular science treatments but does not utilize the level of rigor that is typically encountered in graduate-level treatments. I first give a justification for the hallmark of general relativity, the Einstein field equations, then show how they can be applied to describe a class of universes, and end by briefly reviewing the experimental results that confirm theoretical predictions made by these cosmological models. The intention of this report is not to properly educate a reader on general relativity and cosmology but to expose them to the basic theoretical structure of the matter and should serve as a starting point for the curious reader.
