What is the standard cosmological model that incorporates Normal Matter, Dark Matter, and Dark Energy called?
Answer
The $\Lambda$CDM standard model
The current widely accepted framework used by cosmologists to describe the composition and evolution of the universe is known as the $\Lambda$CDM standard model. This model integrates three primary components: the cosmological constant (Lambda, $\Lambda$), representing dark energy, Cold Dark Matter (CDM), and ordinary baryonic matter. While the proportions of these components derived from measurements are well-constrained, the true physical nature of the two dark components remains the central focus of modern physics research efforts.
