The Great Wall: The Largest Structures in the Universe | Sleepless Knowledge

Описание: The universe is woven into vast structures far larger than galaxies or clusters — immense walls of matter stretching across hundreds of millions of light-years. These structures are not solid objects, but patterns shaped by gravity, dark matter, and the slow expansion of space itself.

In this episode, we explore the Great Walls of the universe: how tiny quantum fluctuations after inflation grew into the cosmic web, how dark matter formed an invisible skeleton guiding galaxies into filaments and sheets, and how modern surveys revealed structures like the CfA Great Wall and the Sloan Great Wall. We also examine the controversial Hercules–Corona Borealis region, pushing the limits of how large cosmic structure can be.

This documentary follows the science behind large-scale structure — from the early universe to the far future — revealing why the universe looks the way it does, why enormous walls don’t break cosmological laws, and how dark energy will eventually freeze this cosmic architecture in place.

A quiet, deeply scientific journey through the largest patterns ever discovered — where gravity, time, and space work together to shape the universe on its grandest scales.
