Question

Quizplus · Accepted Answer

The current prevailing theory is that the universe is accelerating due to an unknown form of energy, called "dark energy," which makes up around 68% of the total energy density of the universe. This dark energy is postulated to have negative pressure, driving the expansion of the universe to accelerate. While various other theories and candidates have been proposed, such as modified gravity, none have yet been able to fully explain the observed data as well as dark energy.
