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.
What happened in the first moments of the universe—before the building blocks of life and the world we know today came into existence? Physicists at the CERN research facility in Switzerland are trying to answer this question ...

For close to a century, physicists have pursued a way to unite gravity with quantum mechanics. Known as quantum gravity, this goal has remained frustratingly out of reach so far. Similarly elusive is the force of dark energy, ...
A tiny UK-developed satellite, roughly the size of a small carry-on suitcase, could help answer one of the biggest questions in cosmology: What happened during the roughly 150 million years of the cosmic dark ages, before ...

Stars and galaxies make up much of the universe's ordinary, observable matter. But for decades, scientists have wrestled with a cosmic conflict: There should be much more.

Deep beneath the French-Swiss border, the world's largest scientific instrument has fallen silent. After years of smashing protons together at nearly the speed of light, CERN's Large Hadron Collider (LHC) has stopped operations ...

Astronomers have used the ages of more than 155,000 stars in the Milky Way to independently estimate the age of the universe, and their findings may be good news for the standard cosmological model. The new research was reported ...
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 ...
