7 Podcast Episodes That Ask the Biggest Questions
Curated by Lindsay Bodanza, creator and host of The Space Between
Questions Left Wide Open
The most compelling questions are often those that become more complicated the longer we examine them. What makes us who we are? What happens when consciousness disappears? How do grief, perception, and experiences at the edges of explanation alter our understanding of reality? These podcasts approach explore experiences that to not fit neatly into any single way of understanding them. They draw on science, philosophy, spiritual traditions, artistic expression, and personal experience to explore big questions we may never know the answer to.
Here are 7 podcasts that explore big questions and how they shape our world.
Hi-Phi Nation
The Self and Survival
This episode begins with extraordinary stories of children who seem to remember past lives, then widens into a philosophical inquiry about memory, identity, consciousness, and survival after death.
Rather than treating reincarnation or the afterlife as something to prove or dismiss, it lets scientists, philosophers, and personal testimony complicate one another, leaving listeners with the deeper question of what would actually have to continue for a self to survive.
Soul Boom
What Does Death Actually Feel Like?
Near-death experiencers Vinnie Tolman and Betty Guadagno describe leaving their bodies, undergoing life reviews, and encountering a love they experienced as unconditional.
Their stories cannot determine what near-death experiences ultimately are, but they invite another question: if contemplating death consistently returns people to love, connection, and service, what might death have to teach us about how to live?
The Space Between
The Continuity of Being
In “The Continuity of Being,” Lindsay Bodanza examines consciousness through the lens of Alzheimer’s disease, asking what, if anything, persists when memory, personality, and the ability to communicate are profoundly altered.
From there, the episode widens the question, considering whether the self is contained by the body or expressed through it as part of a larger pattern. It leaves us asking whether someone who becomes unrecognizable has truly disappeared, or whether we have only lost the means to find them.
Fresh Air
Michael Pollan’s Journey to Understand Consciousness
Terry Gross and Michael Pollan investigate one of science’s most stubborn mysteries: how physical matter produces subjective experience. Their conversation moves among neuroscience, meditation, plant sentience, artificial intelligence, and the elusive nature of the self.
Ultimately, they suggest that consciousness may require forms of inquiry we have not yet developed.
Radiolab
Black Box
Radiolab explores three kinds of black boxes, places where we can observe what goes in and what comes out but cannot fully see what happens inside. Moving through metamorphosis, stage magic, and anesthesia, the episode turns consciousness itself into the deepest hidden chamber.
It asks what disappears when awareness goes offline, what remains active beneath the surface, and whether some transformations can be partly studied without ever becoming fully transparent.
On Being
Nick Cave Loss, Yearning, Transcendence
In this conversation, Nick Cave speaks about grief, music, religion, and the strange nearness of those we have lost. The episode stays with questions that resist definitive answers, including how sorrow changes us, whether absence can become a form of presence, and why music can seem to reach places ordinary language cannot.
Rather than offering closure, it leaves grief as a mystery that can enlarge love, deepen attention, and open a different relationship to meaning.
Unexplainable: The Sound Barrier
What Does Silence Sound Like?
This episode begins with a deceptively simple question: is silence really nothing? Moving through sensory deprivation, anxiety, music, neuroscience, and one of the quietest places in the world, Unexplainable turns silence into a mystery of perception rather than an absence of sound.
It leaves listeners wondering how much of experience is shaped not only by what reaches us, but by what we expect, fear, and learn to hear.
On Pondering Big Questions
A good question doesn’t need us to solve it before it can change us. It can unsettle an assumption, widen our sense of what is possible, or help us see a familiar part of life differently. Some of these episodes remain in uncertainty, while others test extraordinary claims or offer new ways of interpreting familiar mysteries. Together, they show that even when an investigation produces an answer, it can leave us with better questions than the ones we brought to it. I hope something here stays with you long after the episode ends.
