Right now, the leading theory, or standard model, of cosmology is called "Lambda CDM.' Lambda denotes the cosmological constant describing dark energy, and CDM stands for cold dark matter.

The Lambda Cold Dark Matter model suggests that 68 percent of the universe is made up of dark energy. But a new study has questioned whether dark energy exists, citing simulations that found that ...

Furthermore, the model incorporates a cosmological constant (denoted by the Greek capital letter Lambda), which is permitted by Einstein’s theory, but what it actually represents is unknown.

The Lambda CDM model has worked quite well for years, but now observations clearly are pointing to a problem that needs to be solved, and it appears the problem lies with the model," Pesce said.

The BAO map is consistent with the current “Lambda-CDM” model of the universe, which incorporates dark energy and dark matter. Analysis of the data also shows that Einstein’s general theory of ...

The standard cosmological model known as Lambda-CDM (ΛCDM) proposes that dark energy is a constant force in the universe. However, an early “hint” in a new detailed map from the Dark Energy ...

The Lambda-Cold Dark Matter (Lambda-CDM) model struggles to explain the formation of these thirteen satellite galaxies orbiting around Andromeda.

Plugging these into the Lambda-CDM model spat out a Hubble constant of roughly 46,200 mph per million light-years, or roughly 67 kilometers per second per megaparsec.

The DESI collaboration used the second simplest model of our universe after Lambda CDM, which is unremarkable except for its ability to help cosmologists check for deviations from the standard model.
