In this week's episode, David is joined by Dr Paul Sutter, Professor at Stony Brook and a Visiting Professor at Barnard College. Paul is a theoretical cosmologist, who has had a long and productive career in research, but is better known to most for his science communication work. Having one numerous awards, written popular science books and starring in shows like "How the Universe Works", Paul has become a familiar face to many. In this third book, "Rescuing Science: Restoring Trust In an Age of Doubt", Paul explores how the public are losing trust in scientific institutions and what we can do about it.

Cosmologist Renée Hložek discusses axions, dark matter, dark energy, and unraveling the secrets of the universe. They explore the Atacama Cosmology Telescope, the Sunyev-Zaldovich effect, and the Ruben Observatory's capabilities. They also touch on self-interacting dark matter and upcoming missions in astronomy.

Malena Rice, expert in planetary dynamics and detection techniques, discusses the hypothesis of Planet Nine, interstellar objects like Oumuamua and Borisov, propelling objects out of the solar system, rate calculation for object discovery, misalignment angles in exoplanet systems, and limitations of the rare Earth hypothesis.
