What Happens After? The Science of Dying
In this episode, we explore the science of dying. We examine what happens in the brain after cardiac arrest, why consciousness usually fades within seconds, and the remarkable discoveries of brief bursts of brain activity after your heart has stopped.
We also dive into the mystery of near-death experiences. Why do some survivors describe tunnels of light, out-of-body experiences, or profound feelings of peace? Could these experiences be explained? Or are there still unanswered questions about consciousness itself?
Beyond the brain, we follow the body's final biological journey i.e., how different organs shut down, what dying typically feels like, etc.
If you've ever wondered what science can actually tell us about our final moments, this episode is for you.
