Скачать или смотреть Space Stories for Sleep | How Does Light Actually Work?

A single photon, born in the early universe four hundred thousand years after the Big Bang, travels for fourteen billion years across the cosmos—yet experiences no time at all.

Tonight, we explore what light truly is: quantum electromagnetic radiation that behaves as both wave and particle, traveling at the universe's speed limit while experiencing zero time. We'll discover how light bends around black holes, carries information across billions of light-years, and connects you directly to distant stars and ancient galaxies.

Every star you see is showing you its past. Looking into space means looking back in time. The photons entering your eyes right now are eight-minute-old sunlight that traveled ninety-three million miles to let you see. Light is everywhere, connecting everything, making the universe knowable and beautiful.

Subscribe for calm journeys through space — quiet stories about the universe, designed to slow your thoughts and gently carry you into sleep.
