{mosimage}Are we living in the “golden age” of cosmology? Are we close to understanding the nature of the unknown ingredients of the currently most accepted cosmological model and the physics of the early Universe? Or are we rather approaching a paradigm shift? What is dark matter and does it exist? How is it distributed around galaxies and clusters? Is the scientific community open to alternative ideas that may prompt a new scientific revolution – as the Copernican revolution in Galileo’s time?

These, among many others, are the astrophysical, philosophical and sociological questions of modern cosmology and the scientific community that Mauro D’Onofrio and {cb_profile=burigana}Carlo Burigana{/cb_profile} ask some of the most prominent cosmologists of our time. Triggered by these questions and in the spirit of Galileo’s book “Dialogue Concerning the Two Chief World Systems” the roughly 40 interview partners reply in form of essays, with a critical frankness not normally found in reviews, monographs or textbooks.
