10. Λ in Modern Cosmological Models
Today, the cosmological constant holds a central place in the ΛCDM model—the standard framework for cosmology.
This model combines Λ with cold dark matter to describe the universe’s structure, evolution, and fate.
Observations from missions like Planck have confirmed the ΛCDM model’s accuracy, making Λ an essential ingredient in our cosmic recipe and deepening our understanding of how the universe has unfolded over billions of years.
