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

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

Two colliding galaxies have been found to be reorganizing their dwarf satellites, potentially solving a major conundrum ...

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

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.

The standard cosmology model requires dark matter to fit observations, such as accounting for redshift when measuring the brightness of supernovae.

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

Constructing more sophisticated models that contained this constant field was an easier task: they were derived by the Belgian physicist Georges Lemaître, a friend of Einstein’s. The standard ...

Cosmology does not need dark matter or dark energy in an expanding universe that allows the constants of nature to evolve, and light loses energy as it travels vast distances.
