This image shows an array of 512 conductive detectors on the BICEP2 telescope at the South Pole. The technology was fundamental to the discovery of the effect of gravitational waves from the early era of the universe known as the "Inflationary Period". Photo: NASA/JPL-Caltech

How does the telescope at the South Pole that discovered the gravitational waves created by the Big Bang work?
