The topic of 'Limits of Human Understanding' is central to the two podcast episodes provided, as both explore the boundaries of human knowledge and the challenges we face in comprehending the complexities of the universe.

In the episode 'What Happened When A Skeptical Reporter Decided To Investigate The Afterlife | Sebastian Junger', the author and former war reporter Sebastian Junger shares his near-death experience, which prompted him to investigate the possibility of an afterlife from a scientific and rational standpoint. Junger acknowledges the limitations of human understanding when grappling with existential questions and the mysteries of the universe.

Similarly, in the episode 'Staying Curious with William Shatner', Neil deGrasse Tyson and William Shatner discuss the nature of spacetime, the interconnectivity of the universe, and the role of curiosity in fostering introspection. They address the idea that the universe operates according to its own laws, regardless of our comprehension.
