Скачать или смотреть Astronomers Found a Structure Larger Than the Observable Universe

The observable universe stretches 93 billion light-years across—a sphere so vast that light from its edges has been traveling toward us since the dawn of time itself. Within this cosmic horizon, astronomers have catalogued billions of galaxies, mapped immense superclusters, and traced the delicate threads of the cosmic web connecting everything we can see. For decades, we believed we understood the upper limits of cosmic structure—that nothing could exist larger than a few hundred million light-years without violating the fundamental laws of physics. The universe, after all, is only 13.8 billion years old. There simply hasn't been enough time for gravity to pull matter together into structures spanning billions of light-years.
