Abstract
In this note, we explain dark energy and the cosmological constant, and present formulas for both. These predictions are part of our exact solution of Einstein’s equation for a universe in which the curvature varies with time, and the vacuum energy acts upon itself. The predicted value of the cosmological constant agrees with the currently accepted value exactly.
