Perception Limits: A Hidden Reality

Your eyes can only detect light between 430 and 770 terahertz. Your ears max out at 20 kilohertz.

This means the vast majority of electromagnetic waves and sound frequencies pass through you completely

unnoticed. Infrared heat signatures, ultraviolet radiation, radio waves, they're all there

but totally invisible. Bats hear frequencies up to 200 kilohertz. Snakes see infrared. Even mantis shrimp

detect twelve types of color compared to our three. We're essentially walking through

reality blind to most of what actually exists around us. Reality is way bigger than what we perceive.
