Linked from

The 47 pages that link to Hubble's law, each with the reason it gives.

• RedshiftRelated: It connects cosmological redshift measurements with the expansion rate of the universe.

• Doppler effectRelated: Galaxy redshifts help estimate recession speeds, though cosmic expansion is not ordinary Doppler motion.

• Hubble constantRelated: The law uses the Hubble constant as its proportionality factor.

• Big BangRelated: The relation connects observed galaxy redshifts to the expansion history described by the Big Bang.

• Edwin HubbleCompared with: The shared name recognizes Lemaître’s earlier theoretical derivation alongside Hubble’s observational work.

• Orbital periodCompared with: Cosmic expansion is not a bound repeating orbit, so it has no orbital period.

• Cosmological redshiftRelated: Redshift provides the observable used to estimate recession and infer distance.

• CosmologyRelated: Its discovery established that the universe is expanding.

• Peculiar velocityRelated: It describes the smooth recession component from which peculiar motion is distinguished.

• Observable universeRelated: It connects observed galaxy redshifts to distances across the observable region.

• Standard candleRelated: Candle distances paired with recession velocities establish the universe’s expansion rate.

• Georges LemaîtreRelated: Lemaître derived the relation and estimated its proportionality from available observations.

• Steady-state theoryRelated: Expansion would dilute matter unless steady-state theory replenished it.

• Virgo ClusterRelated: Virgo’s motion and distance illustrate departures from the simple expansion relation nearby.

• Mount Wilson ObservatoryRelated: Mount Wilson observations helped establish that the universe is expanding.

• Galaxy redshift surveyRelated: At relatively small cosmological distances, it translates redshift into an approximate distance.

• Friedmann–Lemaître–Robertson–Walker metricRelated: The scale factor’s expansion produces the large-scale distance–velocity relation.

• Tully–Fisher relationRelated: Tully–Fisher distances help calibrate the law’s distance scale.

• Very Large ArrayRelated: Radio observations can reveal neutral hydrogen in galaxies, supporting studies of cosmic expansion.

• Margaret BurbidgeRelated: It provides the standard cosmological interpretation of galaxy redshifts that Burbidge sometimes challenged.

• Vesto SlipherRelated: Slipher’s redshift measurements supplied much of the early velocity evidence behind this relation.

• Alexander FriedmannRelated: The measured recession of galaxies gave observational support to dynamic cosmological models.

• Redshift-space distortionsRelated: Observed redshift combines expansion with peculiar motion around this relation.

• Great AttractorRelated: Separating expansion from local motion is necessary to identify gravitational infall.

• Hubble parameterRelated: Its proportionality constant at the present epoch is the present-day Hubble parameter.

• Accelerating expansion of the universeRelated: It provides the local expansion baseline against which distant supernovae are compared.

• Hubble flowRelated: It quantifies the distance-dependent recession pattern of Hubble flow.

• Astronomical observationRelated: Galaxy redshift and distance measurements established that cosmic expansion can be quantified.

• Carnegie Institution for ScienceRelated: Carnegie astronomer Edwin Hubble used observatory data to establish this relation.

• Cosmic flowRelated: It describes the expansion component that cosmic-flow measurements must separate from local motion.

• Geoffrey BurbidgeRelated: Interpreting this relation as evidence of expansion was central to the cosmological debate Burbidge resisted.

• Lookback timeRelated: It links distance and recession in the local approximation, before full cosmological lookback calculations.

• Scientific lawBroader topic: It links an observed astronomical pattern to the expansion of the universe.

• Big BounceRelated: It measures present expansion, the later phase that a bounce model must connect to.

• Static universeCompared with: The distance–redshift pattern is evidence for cosmic expansion rather than staticity.

• Universe (cosmology)Related: Its measured proportionality provides direct evidence for cosmic expansion.

• Allan SandageNarrower topic: Sandage’s argument concerned the numerical expansion rate in this broader relation.

• Extragalactic astronomyRelated: It connects galaxy redshifts and distances to the expansion rate.

• Physical cosmologyRelated: It established the observed relation between cosmic expansion and galaxy distances.

• Expansion of the UniverseRelated: It links observed galaxy distances and recession speeds to the expansion rate.

• Local SheetRelated: Departures from this relation expose local flows in the sheet.

• Stigler's law of eponymyRelated: Georges Lemaître derived the expansion relation before Edwin Hubble's influential observational paper.

• Tired lightRelated: Both frameworks can reproduce a distance–redshift relation, but interpret it differently.

• Comoving and proper distancesRelated: Its distance depends on which cosmic-time measure is used.

• Local HoleRelated: It underlies many distance estimates for galaxies used in local density studies.

• Recessional velocityRelated: It connects recession speed to distance in the expanding universe.

• Timeline of cosmological theoriesRelated: The observed relation supports an expanding universe rather than a static one.
