Calculate the dark energy density parameter and total dark energy content of the observable universe. Dark energy drives the accelerated expansion of the universe and constitutes about 68% of total energy.
Enter your values below
Current value ≈ 0.68 (68% of total energy)
Used to calculate critical density
Observable universe volume ≈ 4×10⁸⁰ m³
How this calculator works
Dark energy density equals the dark energy density parameter times the critical density of the universe (ρ_crit ≈ 9.47×10⁻²⁷ kg/m³).
