Quizplus · Accepted Answer

The relative densities of dark energy and dark matter in the universe are known to a precision of about 1 part in 100, according to current cosmological measurements. This level of precision is achieved through observations such as the cosmic microwave background radiation, galaxy clustering, and supernovae distances.
