Everything You See Happened 15 Seconds Ago:

The human vision functions with a 15-second delay, which means what you see now has happened in the past.

Everything we see is a combination of the last 15 seconds of visual information, as our brain helps us perceive a stable world by living “in the past.” This mechanism, resembling an app consolidating visual input, smoothes our visual experience over time.

Instead of analyzing every single visual snapshot, our brain creates an average impression based on the past 15 seconds, tricking us into perceiving a stable environment.

This ability explains why we often fail to notice subtle changes that occur over time, preventing the world from feeling chaotic with constant real-time updates. Thanks to this delay, our vision doesn’t make us dizzy or nauseated. Our eyes continuously receive an enormous amount of visual information, comprising shapes, colors, and ever-changing motion.

The brain faces the challenging task of handling these continuous changes due to factors such as light, viewpoint, blinking, and the motion of our eyes, head, and body.

Dealing with the shaking and visual noise it receives, the brain experiences a jittery, messy result similar to a video recorded while walking on a smartphone, representing our visual experience in each moment.
