Ep124 "Why don't we notice gaps in time?"

Consciousness constructs a seamless narrative of time, yet this sense of continuity is an illusion that frequently breaks down. Visual perception relies on saccades—rapid eye movements where the brain suppresses input—yet we perceive a stable world because the brain edits out these gaps. Sleep, anesthesia, and coma demonstrate that time perception depends entirely on memory encoding; without memory, time effectively ceases to exist for the subject. Amnesia cases, such as Henry Moliason, reveal that the loss of episodic memory prevents the formation of a personal timeline, trapping the individual in a permanent present. Furthermore, human cognition lacks an intuitive grasp of deep time, leading to a "temporal fovea" that prioritizes the immediate present while blurring the distant past and future. Ultimately, reality is merely the collection of moments we manage to record, leaving vast stretches of history forgotten.
