New physics needed to explain early expansion of the Universe
... bang, scientists use a model known as lambda CDM (or ΛCDM). The symbol for Lambda Λ refers to Albert Einstein’s cosmological constant which describes the energy density of space – a characteristic that we now associate with dark energy, while...

Researchers create largest-ever 3D map of the Universe
...to be correlated with something so that the oscillations can be measured and used as a ‘standard ruler’ for length scale in cosmology. For this, quasars powered by supermassive black holes at the centres of galaxies were used as they appear as a very...

Life in the universe – common or not?
... currently understood age of the universe (from the Big Bang 13.8 billion years ago). This limit is referred to as a cosmological horizon. Although there is a chance that life might be lurking in subsurface oceans under the icy crust of Jupiter...

Discrepancies in data suggest less dark matter now than after the big bang
... know this because of a discrepancy between the cosmological parameters in the modern Universe compared with those...a lecturer at MIPT's Department of Fundamental Interactions and Cosmology. These parameters are namely the Hubble parameter, which ...

Distant quasars help refine the rate of the expanding Universe
... could hint at "new physics" beyond the standard model of cosmology, say the team. The rate at which the Universe is expanding...The rate of this expansion is determined by the current Standard Cosmological Model, "Lambda CDM", and it has in the past ...

New theory unifies dark matter with dark energy
