Universe

Looking at the universe means looking at everything that exists: space, time, matter, energy, galaxies, stars, planets, forces, and the laws that bind them together. These posts examine the universe from its earliest moments in the Big Bang through to its vast cosmic structure, expansion, dark matter, dark energy, black holes, and possible future. From the smallest particles to the largest superclusters, the universe remains the grand setting for every scientific question about existence, origin, order, and reality itself.
