Is dark matter detected in intergalactic space? Or does it stay close to stars and galaxies?
Hailey AlvarezDark matter exerts gravity, so it clumps up. Astronomers believe that galaxies are really these dark matter clumps with the visible stars and other matter embedded in them.

We find dark matter not only in the vicinity of stars and galaxies but also in intergalactic space; its distribution is concentrated more within galaxies and galaxy clusters, but it is present throughout the universe, including intergalactic space, and is inferred from gravitational effects like gravitational lensing and galaxy cluster motion.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
