KnowraModified gravityLinked fromLinked fromThe 7 pages that link to Modified gravity, each with the reason it gives.All 7Narrower topic 2Compared with 5Dark energyCompared with: They can attribute acceleration to changed gravity rather than a new energy component.Dark matter haloNarrower topic: It frames a broad alternative to interpreting halo-like effects as dark matter.Cosmological constantCompared with: They can mimic the constant’s effects without adding uniform vacuum energy.Lambda-CDM modelCompared with: These theories challenge the model’s assumption that general relativity governs gravity at all scales.Cosmological constant problemCompared with: They seek explanations that need not treat acceleration as ordinary vacuum energy.Accelerating expansion of the universeCompared with: Some models seek acceleration by changing gravity rather than adding a new cosmic component.No-hair theoremNarrower topic: Changing the field equations can change whether black-hole uniqueness holds.
