What Schrödinger's Cat Really Tells Us About Reality

In this mind-bending conversation, Neil deGrasse Tyson and theoretical physicist Sean Carroll unpack the strange reality of quantum mechanics — from entangled particles and wavefunctions to Schrödinger’s legendary cat. What does it really mean for a cat to be both awake and asleep? And how does that tie into the idea that the entire universe shares a single quantum state? Featuring thought experiments, the history of the Copenhagen and Many-Worlds interpretations, and the deep philosophical implications of modern physics, this clip will challenge how you think about observation, reality, and existence itself.
