Missing Memes

Ever lost your keys? Try finding a single photon with an exact frequency! This physics "missing poster" is the quantum equivalent of searching for a needle in a haystack... if the needle could simultaneously exist and not exist! The ridiculously precise frequency (3 × 10^15 Hz) is in the visible light range, which means this little light particle is literally hiding in plain sight. The arrow pointing "out of your screen" suggests it might have quantum tunneled into your dimension. Quick! Check behind your retinas!
