How the Big Bang Has No Center (And More) | Science for Sleep

People picture the Big Bang as an explosion “somewhere.” That’s the trap. The Big Bang wasn’t matter flying into empty space—it was space itself expanding everywhere at once. That’s why there’s no center to point at, no edge to find, and no single location you can label as “where it happened.” In this episode, we rebuild the idea from the ground up: expansion, horizons, the smoothness of the cosmos, inflation, and what we still don’t know. Chapters: The core misunderstanding: not an explosion in space, but the start of expanding space What “beginning” means: space and time turning on together Expansion explained: galaxies don’t fly away—distances grow with space A uniform universe: why everything looks similar in every direction The cosmological principle: no special place, no preferred center The observable limit: horizons and why we can’t see “the whole” universe The horizon problem: why the early universe looks too smooth Inflation: the rapid expansion idea and what it solves Curvature and infinity: the possible shapes of the entire universe Open questions: topology, quantum gravity, and what future data might change If you enjoy science that’s easy to follow at night, subscribe for more.
