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.
On March 11, NASA launched a new space telescope into orbit to explore the origins of the universe. The mission will use sophisticated software, developed at the Arizona Cosmology Lab at the University of Arizona, to analyze ...

The universe has been expanding ever since the Big Bang almost 14 billion years ago, and astronomers believe a kind of invisible force called dark energy is making it accelerate faster.

I've long been fascinated by the fundamental mystery of our universe's origin. In my work, I explore an alternative to the traditional singularity-based models of cosmology. Instead of a universe emerging from an infinitely ...
Water may have first formed 100–200 million years after the Big Bang, according to a modeling paper published in Nature Astronomy. The authors suggest that the formation of water may have occurred in the universe earlier ...

A new analysis of data from the PHENIX experiment at the Relativistic Heavy Ion Collider (RHIC) reveals fresh evidence that collisions of even very small nuclei with large ones might create tiny specks of a quark-gluon plasma ...

At Brookhaven National Laboratory's (BNL's) Relativistic Heavy Ion Collider (RHIC), billions of gold ions race through magnets at nearly the speed of light. Thousands of times per second, they collide head-on, breaking into ...

Astronomers have known for a century that the universe is expanding. We can now trace this expansion over much of its almost 14 billion year history, with important constraints going back to just one second after the Big ...
As physicists continue their struggle to find and explain the origin of dark matter, the approximately 80% of the matter in the universe that we can't see and so far haven't been able to detect, researchers have now proposed ...
In an article published in the Astronomy & Astrophysics journal, new evidence suggests how supermassive black holes, with masses of several billion times that of our sun, formed so rapidly in less than a billion years after ...

Gravity has shaped our cosmos. Its attractive influence turned tiny differences in the amount of matter present in the early universe into the sprawling strands of galaxies we see today. A new study using data from the Dark ...
