The Big Bang theory as a research area encompasses the theoretical, observational, and computational study of the hot, dense early universe and its subsequent expansion, structure formation, and thermal history. It integrates general relativity, quantum field theory, nuclear physics, and plasma physics to model processes such as primordial nucleosynthesis, recombination, and inflation, and it interprets empirical data from the cosmic microwave background, large-scale structure surveys, and high-redshift observations. Research in this domain refines cosmological parameters, tests fundamental physics (e.g., dark matter, dark energy, curvature), and investigates deviations from or extensions to the standard ΛCDM cosmological model.
Astronomers at Durham University have made a major advance in understanding how galaxies formed and evolved in the early universe. Using powerful new observations, the team discovered the most distant example ever found of ...

There are multiple ways to form black holes. The one most commonly taught in high school physics classes is that they are created from the collapse of a dying star. But there is another class of black holes, known as primordial ...

Just a few hundred million years after the Big Bang, the universe was a dark and simple place. There were no galaxies like the Milky Way, no planets, and no heavy elements such as carbon or oxygen. Instead, vast clouds of ...

Stars shine because atoms fuse in their interiors, releasing energy. When a very massive star has exhausted its nuclear fuel, radiation pressure can no longer provide sufficient counterforce to gravity. The star then collapses ...

A supermassive black hole lies at the heart of every galaxy, including the Milky Way. When a black hole is active, it pulls material in as a whirlpool of high-temperature gas and dust. As this cosmic material piles up and ...

Which comes first, the galaxy or the black hole? We don't know, but scientists have long thought it could be the galaxy: Large stars within an existing galaxy consume their fuel and collapse to form black holes, which can ...
