What Happens If You Reach the Edge of the Universe?

What's at the edge of the universe? Is there a wall? A boundary? Or does space just go on forever? This is one of the most profound questions in cosmology—and the answer is far stranger than you think. The universe might be infinite. It might curve back on itself like the surface of a sphere. Or it might have an actual edge, beyond which exists... something we don't have words for. What you'll discover in this video: The difference between the observable universe (46 billion light-years) and the actual universe (possibly infinite) Why asking "where is the edge?" might be the wrong question entirely Three possibilities: infinite universe, finite but curved, or finite with an edge What the cosmic microwave background tells us about the shape of space Why the universe appears flat (and what that means for boundaries) The ancient Greek thought experiment that still stumps physicists today How Einstein's general relativity allows space to curve back on itself Multiverse theories: could our universe be a bubble in something larger? What "beyond the universe" could even mean (spoiler: it breaks physics) Why we might be living inside a cosmic Pac-Man screen The Apollo 8 Earthrise moment and what it taught us about boundaries 📚 Featured Topics: Edge of the universe, observable universe vs actual universe, cosmic horizon, infinite space, closed universe geometry, flat universe, open universe, Einstein's field equations, cosmic microwave background, shape of the universe, topology of space, multiverse theory, membrane cosmology, bulk space, higher dimensions, Archytas's spear paradox, Flatland analogy, dark energy expansion, cosmic acceleration, untestable physics, and why some questions might not have answers A calming, intellectually rich journey to the ultimate horizon—or the realization that horizons might be illusions we create to make infinity comprehensible.
