Glimpses of the Big Bang Using Balloon- and Satellite-based Experiments

Balloon borne and satellite experiments which measure the 'cosmic microwave background radiation' have revolutionized our understanding of the universe. They have elucidated physical mechanisms occurring at times close to the big bang, given us new insights about the evolution of the universe, and perhaps are telling us about the fate of the universe. I will describe the origin of the cosmic microwave background radiation and the information it contains. I will also discuss our own experiments, which are mostly balloon-based, review our results, and put them in the broader astrophysical context.
