Host Miriam Frankel delves into some of the great mysteries still puzzling the world's top physicists in this new series from The Conversation. This podcast will take you on a mind-blowing journey from the smallest to the largest conundrums, exploring curled-up dimensions, consciousness and parallel universes on the way.Themes and summary (AI-generated based on podcaster-provided show and episode descriptions):
➤ Unsolved physics foundations • Theory of everything, standard model limits • Quantum reality and measurement • Emergence of life and consciousness • Multiverse and testability • Fine-tuning, fundamental constants • Nature of time, arrow of time illusionThis podcast explores open questions at the frontiers of modern physics, guided by host Miriam Frankel and conversations with researchers and philosophers of physics. Across the series, it focuses on where today’s most successful theories seem incomplete, inconsistent, or difficult to interpret, and what new conceptual frameworks might be needed to make progress.
A recurring theme is the search for deeper unification in fundamental physics: how existing models describe forces and particles with high precision yet still leave gaps when compared against one another, and what it would mean to have a single overarching account of nature. The podcast also returns often to foundational issues in quantum mechanics, including whether the theory describes an objective external reality, how observation and measurement fit into the picture, and what competing interpretations imply about determinism and the nature of physical facts.
On larger scales, it examines cosmological ideas such as parallel universes and the multiverse, emphasizing questions of scientific testability and what kinds of evidence would count. Closely related is the “fine-tuning” problem: why physical constants appear to fall within ranges that allow long-lived stars, complex chemistry, and the possibility of life.
The series also looks at physics-informed approaches to life and consciousness, asking how living, information-processing systems could emerge from non-living matter. Another major thread is time itself—whether time as humans experience it is fundamental or emergent, how it connects to physical laws, and whether phenomena like the arrow of time could be explained in more basic terms.
