Cosmological parameter · ΩΛ
Dark Energy Density (ΩΛ)
The fraction of the universe's total energy density carried by dark energy — the component driving the accelerating expansion. In the standard model it is the cosmological constant Λ, and it makes up the majority of the present-day energy budget.
