The ratio between this value and the critical density of the universe is approximately 0.7, and thatvalue corresponds to the dark energy density.
The ratio between this value and the critical density of the universe is approximately 0.7, and thatvalue corresponds to the dark energy density. It is multiplied by one third of the square of the speedof light in the Friedmann equation. Taking this quantity divided by 8 pi gives the vacuum energydensity. Quantum field theories unusually predict its value to be 120 orders of magnitude greaterthan its real value. This value originally appeared multiplying the metric tensor in the (*) EinsteinField Equations in order to maintain a stationary universe. Einstein referred to its conception as the "biggestblunder" of his life since the universe is expanding. For 10 points, identify this mysterious value in generalrelativity symbolized lambda.
