For more than two decades, the standard model of cosmology has stood as a reliable guide to the universe. Known as Lambda ...

Researchers are using supercomputer simulations grounded in Einstein’s relativity to test scenarios about what may have ...

An impossibly bright galaxy is forcing scientists to rewrite the rules of the Big Bang’s aftermath. Here’s what you’ll learn ...

A recent resurgence of interest in a bold cosmological theory has reignited debate about the nature of dark matter, the Big Bang, and the possible existence of a mirror universe. Originally proposed ...

Cosmic microwave background data support cosmology’s standard model but retain a mystery about the universe’s expansion rate.

New data on baryon acoustic oscillations strengthen the case for a local cosmic void. The finding offers a possible solution to the Hubble tension. When we look at the night sky, it can appear as ...

The standard cosmology models today based on Lemaître's work, and are referred to as Λ Cold Dark Matter (ΛCDM) models. The DESI measurements on their own are completely consistent with this model.

For decades, scientists suspected this ion played a critical role in cooling the early cosmos, helping the first gas clouds ...

How can the tiniest particles and the vast structure of the universe be explained using the same kind of mathematics? This puzzle is the focus of recent research by mathematicians Claudia Fevola ...

Matrix models have emerged as a powerful framework in theoretical physics, offering a nonperturbative approach to describing quantum space-time. In these models, fundamental degrees of freedom are ...

To study the origin and evolution of the universe, physicists rely on theories that describe the statistical relationships ...
