What a Photon Really Is... And Why It’s So Strange

A photon has no mass, yet carries energy. It travels at 300,000 km/s, yet from its perspective—if we could define one—no time passes at all. It behaves as a wave when traveling through space, then as a particle when detected—and no one fully understands why. In this calming long-form space documentary, we explore the true nature of light and why physicists still call it the most mysterious thing in the universe. From Newton's "corpuscles" to Einstein's light quanta to modern quantum electrodynamics, the story of the photon is the story of humanity's struggle to understand reality itself. By the end, you'll never look at light the same way again. #quantumphysics #photon #einstein #physics #speedoflight #scienceexplained #waveparticleduality
