Where Do Photons Go When the Lights Go Out?
Physics By Light

You flick a switch, and absolute pitch black fills the room. It is the most mundane, ordinary action in the human experience. To our biological eyes, the light simply vanishes, fading away into nothingness like smoke in the wind. But physics tells a much darker, far more violent story.
Light is not an abstraction; it is made of trillions of tangible, physical particles called photons. They hold kinetic energy, possess momentum, and race across space at one hundred and eighty-six thousand miles per second. When you sever the power, those countless billions of photons do not just evaporate. They are trapped inside a geometric box, bouncing millions of times per second in a frantic, microscopic pinball game before they are systematically hunted down, swallowed, and annihilated by the matter of your walls, furniture, and skin.
In this video, we explore the terrifying, hidden reality of what happens in the billionths of a second after you turn off the light. We unravel the physics of atomic absorption, the conversion of visible light into invisible thermal radiation, and the true fate of the photons that manage to escape your room and drift out into the infinite cosmos.
If you want to continue exposing the illusions of the human senses, unraveling the deepest mysteries of quantum mechanics, and exploring the strange, terrifying, and beautiful laws of theoretical physics, consider subscribing and turning on notifications for more cinematic science journeys.
