Introduction
Most of the matter (greater than 80%) in the universe is dark, meaning that it interacts very weakly with light and therefore cannot be seen directly with our most powerful telescopes. Therefore, we know very little about what kind of particle might make up this so-called dark matter. So how do we know it is really there, and how can we hope to discover its properties?

In this talk, I will describe some of the strongest lines of evidence for the existence of dark matter, and what this can teach us about our galaxy and the universe more broadly. I will introduce several of the most promising candidate particles for explaining the existence of dark matter, and how they differ in experimental predictions.

Along the way, I will describe my own research into dark objects known as boson stars, which can provide new ways of searching for these elusive dark particles in hopes of solving one of the greatest mysteries in physics.
