In this video, How the Big Bang Governs the Texture of Our Universe, we explore the concept of cosmic inhomogeneities—using zebras as an analogy for clumps of matter scattered throughout the universe. This visual rendering takes up a fundamental question about the texture of space: Is it smooth or bumpy? Moments after the big bang, there was a period of inflation, in which the universe expanded exponentially. Clumps and voids formed, creating a bumpy texture on relatively small scales. Our universe remains smooth, or homogeneous, over very long distances, where gravitational collapse does not hold sway.
