If $\varOmega$_matter+ $\varOmega$_$\wedge$ = 1 today and dark energy was a cosmological constant,the universe will: A) expand forever B) slow its expansion but never reverse it C) stop expanding and eventually collapse D) oscillate between expansion and collapse

Question

Quizplus · Accepted Answer

The equation given suggests the conservation of energy, where the matter energy density and the dark energy density are balanced. If the dark energy is a cosmological constant, it means its energy density remains constant throughout the expansion. In such a scenario, the gravitational attraction due to matter would weaken due to the expansion, and eventually, the dark energy would dominate, causing the expansion to accelerate. Therefore, the universe would expand forever.
