With new astronomical instruments and new knowledge of fundamental physics our understanding of the universe is developing fast. The new understanding of the universe from its Dark Ages, after the Big Bang, to the current acceleration with planets, stars, galaxies and life raises a lot of questions. In this podcast, Science Journalist Jens Degett interviews Associate Professor Darach Watson from the Cosmic Dawn Center at the Niels Bohr Institute, University of Copenhagen. The podcast is part of our project "Danish Space Research" supported by Otto Mønsteds Foundation and Thomas B. Thriges Foundation. Photo credit: Jens Degett, © Science Stories ApS
