The 45 pages that link to Expansion of the Universe, each with the reason it gives.

• James Webb Space TelescopeRelated: Expansion stretches ancient light into infrared wavelengths Webb can detect.

• Big Bang nucleosynthesisRelated: Expansion cooled the plasma and ended nucleosynthesis before heavier elements could form abundantly.

• Big BangRelated: It describes cosmic expansion without requiring galaxies to fly from a central point through space.

• Observable universeRelated: Expansion makes the observable radius larger than the universe’s age multiplied by light speed.

• AstrophysicsRelated: Its dynamics connect galaxy observations to the universe's contents and history.

• ReionizationRelated: Expansion stretched radiation and diluted matter while the ionized regions grew.

• George GamowRelated: Expansion cools the primordial universe, setting the conditions for the nucleosynthesis Gamow studied.

• Comoving distanceRelated: Comoving distance factors out this expansion to keep the coordinate separation fixed.

• Age of the universeRelated: The universe's expansion history is central to calculating elapsed cosmic time.

• Hubble flowRelated: It produces the large-scale recession described by Hubble flow without requiring galaxies to move through space.

• Primordial nucleosynthesisRelated: Expansion cooled and diluted the plasma, eventually making nuclear reactions too slow.

• Ralph AlpherRelated: Expansion cooled the early universe and limited the time available for nuclear reactions in Alpher’s model.

• Heat death of the universeRelated: Expansion dilutes matter and radiation and can isolate distant regions.

• Dark Energy SurveyRelated: Measuring its history was a central aim of the survey.

• Robert HermanRelated: Expansion stretches the relic radiation’s wavelengths and lowers its temperature.

• Outer spaceRelated: It changes large-scale distances in space without requiring galaxies to move through space in the ordinary sense.

• Quark epochRelated: Expansion lowered the plasma’s temperature and density.

• Raychaudhuri equationRelated: Applied to cosmological fluid worldlines, the equation constrains expansion and gravitational collapse.

• Universe (cosmology)Related: It accounts for large-scale cosmic expansion without requiring galaxies to move through space from a central point.

• Penrose–Hawking singularity theoremsRelated: Hawking-type results use sufficiently strong expansion to establish past-directed incompleteness.

• Physical cosmologyRelated: Its changing rate is central to reconstructing cosmic history and forecasting the universe’s fate.

• Structure formationRelated: Expansion competes with gravity and sets the rate at which fluctuations can grow.

• Chronology of the universeRelated: Expansion drives the cooling that links successive eras in cosmic history.

• SN 1572Related: Measurements of distant Type Ia supernovae revealed the expansion’s accelerating rate.
