How Large the Universe Must Be to Look This Smooth | Space Science For Sleep

Why does the universe look so incredibly smooth — even across regions that have never interacted? In this video, we explore how large the universe must be to appear this uniform, and what that tells us about cosmic inflation, the Big Bang, and the structure of space-time itself. We’ll break down the horizon problem, the flatness problem, and the mystery of the cosmic microwave background, revealing how the universe's homogeneity could mean it's far larger than we can ever observe. Is our universe just a small patch in an unimaginably vast cosmos? Or is there a deeper reason for this eerie smoothness? Join us as we dive into modern cosmology, the scale of the observable universe, and theories that stretch the limits of our understanding of reality. #UniverseSize #CosmicInflation #BigBangTheory
