Guest:
Dr. Andy Tomkins – Geologist, Professor at Monash University, and lead author of the groundbreaking study proposing that Earth once had a Saturn-like ring system.

The Cosmic Scoop:
What if Earth once had rings like Saturn? Dr. Andy Tomkins joins Markus to unravel the evidence that, 466 million years ago, a colossal asteroid breakup may have encircled our planet with a shimmering band of debris. From the science of ancient meteorites to the climate effects of planetary rings, this episode explores how cosmic events have shaped our world—and what they might mean for life, extinction, and the future of planetary science.

Quotable Insights:

• “The evidence needs to be gathered a bit more still, but we think that ring period could have lasted for 20 to 40 million years.”
• “You can imagine looking up and seeing this ephemeral, light-shaded band in the sky.”
• “Life diversifies quickly when it’s responding to a challenge.”
• “Rings are ephemeral—they don’t last very long.”
• “Earth is compositionally not that special. The right ingredients for life are distributed everywhere throughout the universe.”

Guest: Dr. Bhavya Lal – Former NASA Chief Technologist, MIT-trained nuclear engineer, and architect of U.S. space nuclear policy.

The Cosmic Scoop:
Nuclear power’s bad Earthly reputation hides its potential as a lifeline beyond our planet. Space is already radioactive—and if we want to stay and build on the Moon, Mars, or Europa, nuclear offers “power abundance” solar can’t match. Dr. Lal explains why, covering tech, safety, law, history, and why the next space era may finally embrace it.

Quotable Insights:

• “Solar lets you visit. Nuclear lets you stay and build.”
• “Without nuclear, we design for scarcity. With nuclear, we design for capability.”
• “Adding nuclear in space is like pouring water in a hurricane—it barely registers.”
• “We are entering an era of abundance.”

🚀 The Cosmic Scoop

In this expansive and deeply human conversation, Phnam Bagley challenges everything we think we know about architecture. From floating tables to engineered space hearts, she reimagines what it means to design for a future where gravity is optional and emotion is essential.

Together, we explore the untold questions of life in space:

• What is a “table” without gravity?
• Can architecture heal isolation?
• Do space-born humans need new organs?
• And above all: Are we building habitats—or are we building ourselves anew?

This isn’t just about design. It’s existential. And it’s urgent.

💬 Quotable Insights

💐 “You don’t design for the void. You design for the soul inside it.”
 💐 “Maybe you don’t need a flat table. Maybe you need a soft, spherical one with holes to hold your apple in zero-g.”
 💐 “If the ground disappears beneath you, maybe it’s time to build one inside yourself.”
 💐 “The aesthetics of survival is still survival.”

Guest Introduction:
In an extraordinary fusion of art, engineering, and cosmic ambition, Swedish artist Mikael Genberg and space engineer Emil Vinterhav have realized what many deemed impossible—a traditional Swedish red house, journeying through space toward the lunar surface. This Moonhouse symbolizes humanity’s unyielding aspiration and our innate desire to explore, challenge limits, and leave lasting footprints in new worlds.

Key Discussion Points:

• The Birth of a Vision: Mikael’s inspiration and the initial disbelief surrounding the idea of placing a symbolic red house on the moon.
• Journey to the Moon: The innovative route and the four-and-a-half-month voyage that optimizes energy efficiency.
• Art Meets Engineering: How Emil and Mikael navigated the cultural and technical divides, bringing poetic creativity together with precise engineering.
• From Idea to Reality: The rigorous process, from designing a space-qualified paint in Mikael’s kitchen to comprehensive vibration and vacuum testing.
• The Ultimate Longevity: Reflections on the permanence of the house as a cosmic art piece that will outlive human civilization, serving as an enduring symbol.
• Emotional Launch: Experiences at Kennedy Space Center, from personal anticipation to the profound realization of their dreams ascending into space.
• Ethical Considerations: Addressing the philosophical implications of leaving human artifacts on celestial bodies and how this project enriches human cultural consciousness.

🎙 Guest: Dr. Claudia Schnugg, Curator of the Universe Pavilion at the Venice Biennale & Art-Science Visionary

The Cosmic Scoop:

What if art could transform how we design habitats beyond Earth—and inspire new ways to live here at home? Dr. Claudia Schnugg is making this vision a reality. As curator of the groundbreaking Universe Pavilion at the prestigious 2025 Venice Architecture Biennale, she merges indigenous wisdom, aesthetic dialogue, and rigorous science to reshape how we think about shelter, community, and our cosmic future.

In this episode, Claudia guides us from pioneering Austrian yeast experiments in circular life support systems to ancient Aboriginal star maps navigating by dark patches in the Milky Way.

Quotable Insights:

💡 “Experience can reveal what expertise alone can’t. That’s where artists make the invisible visible.”
 💡 “To shelter in space isn’t just about engineering—it’s about redefining what it means to be at home.”
