KnowraDark energyLinked fromLinked fromThe 64 pages that link to Dark energy, each with the reason it gives.All 64Related 48Narrower topic 8Compared with 8Dark matterCompared with: It is often confused with dark matter, but affects cosmic expansion rather than clustering as matter.Fritz ZwickyCompared with: Unlike Zwicky’s proposed dark matter, dark energy addresses cosmic expansion rather than excess gravitational mass.Baryonic matterCompared with: It contributes to the cosmic energy budget but is not a form of matter.Gravitationally bound systemCompared with: Its large-scale repulsive effect competes with gravity but does not unbind small systems.Modified gravityCompared with: It is the principal alternative explanation that modified gravity seeks to replace or reinterpret.Astronomical objectCompared with: It affects cosmic structure but is not established as an astronomical object.Dipole repellerCompared with: Dark energy accelerates cosmic expansion broadly; the repeller is a local effect of uneven matter density.Fifth forceCompared with: Some scalar fields proposed for cosmic acceleration also predict fifth forces.
