Did you know that most of reality is invisible and inaudible to us? Our senses give us only a tiny glimpse of the world – just enough to survive, but nowhere near the full picture.
🔹 Our eyes detect light between 380-770 nanometers, meaning we can’t see radio waves, microwaves, infrared radiation, ultraviolet rays, X-rays and gamma rays.
🔹 Our ears pick up sound between 20 Hz and 20 kHz, missing infrasound (used by elephants) and ultrasound (heard by dogs, bats and dolphins).
Beyond these limits, entire worlds exist: radio waves carry conversations through the air, deep-sea creatures communicate in frequencies we’ll never hear, and heat signatures surround us, unseen. From the neutrinos streaming through us to the mystery of dark matter and energy, the universe is filled with invisible forces shaping everything around us.
Thankfully, we're not stuck with our basic senses. Technology helps us see and hear beyond our natural limits. Infrared cameras let us see in the dark, ultrasound helps doctors look inside the body, and radio telescopes listen to cosmic whispers from across the universe.
But even with all our tools, we’re still missing something. We may never sense them directly, but that doesn’t mean they aren’t there.
