Question

Quizplus · Accepted Answer

The equation Wmₐttₑᵣ + WL = 1 describes the energy content of the universe, where Wm represents the matter density and WL represents the dark energy density. If the dark energy density is constant (as it would be if it were a cosmological constant), then it will dominate the expansion of the universe when the matter density becomes diluted as the universe expands.

In this scenario, the universe will continue to expand at an accelerating rate, and it will do so forever. This is consistent with current observations of the cosmic microwave background radiation and the large-scale structure of the universe. Therefore, the correct choice is A) expand forever.
