"From a Morning Walk to the Edge of the Universe"　朝の散歩で宇宙まで飛んだ話

This audio recording captures a casual conversation that started with a listener's random thought during a morning walk. It explores themes like how trees grow, how humans move across the world, and how our perception of time shifts. The discussion moves from comparing the endless growth of trees to the limited lifespan of humans, to layering time in new ways, and eventually zooming out to see everything from a cosmic perspective. It’s a thought experiment that takes you on a journey from everyday questions to deep, universal truths—reminding us how curiosity can turn even the simplest wonderings into something profound.
