One of the current frontiers in cosmological research is the search for the imprint of gravitational waves in the polarization pattern of the Cosmic Microwave Background (CMB). Such gravitational waves are hypothesized to have been produced at the very beginning of time during an ultra brief burst of exponential expansion – called Inflation. The BICEP /Keck telescopes observe from the South Pole in Antarctica, and are the current world leaders in this experimental quest. I will describe the telescopes, the data, and the analysis which leads to the current limit on the tensor-to-scalar ratio of r
