Feynman Explain: That the Universe Is Full of Stars but Why Is It Dark

Описание: Have you ever wondered why the night sky is dark? It seems obvious — the sun sets, and darkness follows. But physics tells a far stranger story. If the universe worked the way scientists once imagined, the sky should blaze with endless light — a white-hot ocean of stars as bright as the sun itself.

In this video, inspired by Richard Feynman’s unique way of explaining nature, we dive into Olbers’ Paradox — a simple question that shook our understanding of the cosmos. If space is filled with countless stars, why isn’t the sky glowing everywhere we look? The answer leads us away from the idea of a static universe and toward something far more dramatic: a universe that expands, evolves, and carries the echoes of its explosive birth.

Picture yourself standing inside an infinite forest. Every direction you look, your view eventually meets a tree. If the universe were an endless, unchanging field of stars, your eyes should meet light at every point. To resolve this mystery, we must rethink reality itself — imagining space like a rising raisin cake expanding in the oven, and time as a vast “cosmic sausage,” where past, present, and future are simply different slices of one grand structure.

So what does the darkness above us truly mean? It isn’t emptiness — it’s history. The night sky is evidence that the universe had a beginning. It’s a reminder that light from distant regions is still traveling toward us, carrying the story of the Big Bang across billions of years.
