KnowraCosmological constantLinked fromLinked fromThe 48 pages that link to Cosmological constant, each with the reason it gives.All 48Broader topic 3Related 35Compared with 10Cosmic inflationCompared with: Unlike inflation, it describes the universe's present acceleration rather than a proposed early episode.Hubble constantCompared with: It can influence cosmic expansion but is not itself an expansion rate.Zero-point energyCompared with: The enormous naive vacuum-energy estimate is distinct from the observed cosmological constant.Gravitational constantCompared with: Both appear in relativistic gravity, but only G controls matter-curvature coupling.Scale factorCompared with: It can drive accelerated scale-factor growth but is a source of expansion, not a measure of size.Hubble parameterCompared with: It influences the evolution of the Hubble parameter but is not itself an expansion rate.Big RipCompared with: A constant density produces acceleration without the density growth needed for a Big Rip.Cosmological parametersCompared with: It is the simplest fixed model for the dark-energy density parameter.Modified gravityCompared with: It explains acceleration within general relativity, unlike modifications that change gravity itself.Inflationary epochCompared with: It illustrates how vacuum-like energy can accelerate expansion, though it does not by itself specify inflation’s end.
