Cosmic gravitational wave background is a relict of the Cosmic inflation, which can be measured by examing the polarization of the Cosmic microwave background radiation. It is the result of three things, inflationary expansion of space itself, reheating after inflation and turbulent fluid mixing of matter and radiation. ^[1]
