12. The Cosmic Web
On the largest scales, the universe is woven together by an immense structure known as the cosmic web. This intricate network is made of filaments of dark matter and gas, stretching across billions of light-years and linking clusters of galaxies. Detected through techniques like gravitational lensing and detailed galaxy surveys, the cosmic web eerily resembles a vast neural network. It’s a stunning reminder of the universe’s hidden order and interconnection. Source: Nature
