SoT Special 013 – Gravitational Waves and Cosmic Inflation

SoT_Special_013_downloadLast Monday, astronomers announced what has been described as “the biggest thing since dark energy” – detection of gravitational waves from the afterglow of the big bang. We got astronomer Dr. Alan Duffy from Swinburne University on to tell us what that means, and what it says about the very early stages of our Universe.
