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 ...

To astronomers in the 1990s, these three facts were self-evident: The universe is expanding; all the matter in the universe ...

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

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

(A megaparsec equals 3.26 million light-years.) Widely accepted cosmology models have used light from the early universe to put the Hubble constant of universe expansion at about 67 to 68 km/s/Mpc.

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

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

This new theory proposes that black holes could actually be tiny "bubbles". This involves the conversion of matter into dark ...

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 ...
