The Universe appears to be flat, accelerating and lightweight. In this talk, I will explain what these terms mean, how we developed this view and its implications. I will also discuss the connection between cosmology and particle physics experiments being conducted at accelerators and in underground laboratories. I will conclude with a description of some proposed telescopes that will help us understand much more about the geometry, expansion and contents of our Universe.
