What cosmological function is attributed to Dark Energy in contrast to Dark Matter?
Answer
Acting as a pervasive, repulsive force pushing the universe apart at an increasing rate
Dark energy functions opposite to the attractive force of gravity exerted by dark matter. It is described as a repulsive pressure intrinsic to space itself, conceptually like a constant vacuum energy. As space expands and more space comes into existence, this energy density increases its effect, causing the expansion of the universe to accelerate over time. This repulsive nature dictates the large-scale geometry and ultimate fate of the cosmos, acting as the engine driving separation between distant structures.
