Fighter pilots and test subjects who blacked out in Air Force centrifuges described tunnel vision, bright lights, a sense of floating, and sometimes seeing themselves from outside, though their hearts never stopped. Over 16 years, aerospace physician James Whinnery studied nearly 1,000 of these G-LOC blackouts (G-force induced loss of consciousness). This video follows how scientists have tested the near death experience: the AWARE studies that hid pictures near hospital ceilings, brain recordings from people as their hearts stopped, a drug that produced something very like it, and the case of Pam Reynolds. The experiences are real, and many people say they changed their lives. Science can say so far that the brain doesn’t always switch off at that moment; what it all means is still an open question.
