The True Scale of 2 Billion Galaxies | Documentary For Sleep

Flying Through Every Galaxy In Our Observable Universe | Documentary For Sleep Right now, as you watch this, light from the most distant galaxy humanity has ever found is hurtling toward us at 186,000 miles per second. And that light began its journey when the universe was only a few hundred million years old—before Earth existed, before our Sun ignited, long before the Milky Way became anything recognizable. But here’s the part that shatters everything you think you know: our observable universe doesn’t contain hundreds of billions of galaxies… it contains trillions. And many of them shouldn’t even exist according to our current physics. In the next moments, we’ll dive through the cosmic web itself—witnessing colossal galaxy collisions, impossible structures, and ancient light that has crossed 13 billion years of darkness just to reach us.
