…ultraviolet and infrared light remain invisible, and ultrasonic or infrasonic sounds go unheard. Yet, these unseen and unheard frequencies exist all around us, influencing nature and our bodies in ways we may not realize.
Most of physical reality is invisible to us, according to science.
95% of the cosmos may be forever beyond our ability to sense or detect it.
Our eyes detect light within a narrow range of 380-770 nanometers, while our ears register sound between 20 Hz and 20 kHz.
Beyond these limits, ultraviolet and infrared light remain invisible, and ultrasonic or infrasonic sounds go unheard. Yet, these unseen and unheard frequencies exist all around us, influencing nature and our bodies in ways we may not realize.
From radio waves to deep-sea whale calls, countless signals move through the air and environment, unnoticed by human senses. Modern technology, like infrared cameras and ultrasonic sensors, helps bridge this sensory gap, revealing an unseen world filled with vital information. Still, what else might we be missing?
For example, neutrinos are abundant subatomic particles that pass through almost everything — including our bodies — and only very rarely interact with matter.
And we haven't even started to talk about things like dark matter and dark energy.
