Physics & Philosophy with Sean Carroll
"Our brain does not perceive the present. Our brain puts together a picture of the world that is on a slight time delay, like our brain wants to be able to bleep out things that it doesn't like... roughly think about 40 or 50 milliseconds of time is a little window in which your brain collects things and says, I'm going to put this together into a picture."
Carroll revealed that human perception operates on a 40-50 millisecond delay, with the brain actively constructing what we experience as the present moment. This neurological processing allows the brain to synchronize sensory inputs like sight and sound, even fabricating information to complete coherent mental pictures of reality.
