I once watched a frog perched on a rock in the middle of a small pond, its throat pulsing with life. As it released its deep, resonant croak, the water transformed invisible sound into visible waves, rippling outward in perfect circles from center to edge. The unseen made seen.

Every day, we use microwaves, satellites, 5G, Wi-Fi, and Bluetooth… invisible technologies that manifest in physical reality. We cannot see Bluetooth or Wi-Fi pulsing through the air, but we connect wirelessly and video call someone on the other side of the world. All done through invisible waves dancing around us. People do not question this. They believe in it.
