A Universe Expansion Phenomenon is a cosmological-scale metric physical phenomenon that involves the continuous increase of spatial distances between gravitationally unbound objects throughout cosmic time.
- AKA: Metric Expansion of Space, Cosmic Expansion Phenomenon, Hubble Expansion Phenomenon.
- Context:
- It can typically stretch Universe Spatial Metrics causing universe wavelength redshifts and universe distance increases.
- It can typically cool Universe Temperature Distributions through universe adiabatic expansions and universe photon dilution.
- It can typically decrease Universe Matter Densityes via universe volume increases while conserving universe total mass-energy.
- It can typically generate Universe Cosmological Horizons limiting universe observable regions and universe causal connections.
- It can typically drive Universe Structure Formations by amplifying universe density fluctuations into universe galaxy clusters.
- ...
- It can often exhibit Universe Acceleration Phases driven by universe dark energys or universe cosmological constants.
- It can often preserve Universe Homogeneity Propertyes at universe large scales despite universe local inhomogeneityes.
- It can often create Universe Relic Radiations like universe cosmic microwave backgrounds from universe early epochs.
- It can often influence Universe Fate Scenarios determining universe heat deaths or universe big rips.
- ...
- It can range from being a Decelerating Universe Expansion Phenomenon to being an Accelerating Universe Expansion Phenomenon, depending on its universe energy content.
- It can range from being a Linear Universe Expansion Phenomenon to being an Exponential Universe Expansion Phenomenon, depending on its universe expansion rate.
- It can range from being a Early Universe Expansion Phenomenon to being a Late Universe Expansion Phenomenon, depending on its universe cosmic epoch.
- It can range from being a Isotropic Universe Expansion Phenomenon to being an Anisotropic Universe Expansion Phenomenon, depending on its universe directional uniformity.
- It can range from being a Observable Universe Expansion Phenomenon to being a Beyond-Horizon Universe Expansion Phenomenon, depending on its universe detection scope.
- ...
- It can integrate with Big Bang Events for universe origin understanding.
- It can connect to Dark Energy Phenomenons for universe acceleration explanation.
- It can interface with Cosmic Microwave Backgrounds for universe expansion measurement.
- It can synchronize with Type Ia Supernova Observations for universe distance calibration.
- It can relate to Cosmic Threshold Moment Events for universe complexity timing.

- Example(s):
- Early Universe Expansion Phenomenons, such as:
- Inflationary Universe Expansion Phenomenon (10^-32 seconds), with universe exponential growths solving universe horizon problems.
- Radiation-Dominated Universe Expansion Phenomenon (1 second - 47,000 years), with universe decelerations from universe photon pressure.
- Matter-Dominated Universe Expansion Phenomenon (47,000 years - 9.8 billion years), with universe gravitational slowing.
- Observational Universe Expansion Phenomenons, such as:
- Hubble Universe Expansion Phenomenon (1929), discovering universe galaxy recessions proportional to universe distance.
- Accelerating Universe Expansion Phenomenon (1998), revealing universe unexpected speedups from universe type Ia supernovae.
- Theoretical Universe Expansion Phenomenons, such as:
- Future Universe Expansion Phenomenons, such as:
- Dark Energy Dominated Universe Expansion Phenomenon, leading to universe exponential growths and universe structure isolation.
- Big Rip Universe Expansion Phenomenon, potentially tearing apart universe bound structures at universe finite time.
- ...
- Early Universe Expansion Phenomenons, such as:
- Counter-Example(s):
- Local Gravitational Contraction, which opposes expansions at galaxy scales unlike universe expansion phenomenons.
- Doppler Shift Effect, which results from relative motions rather than space expansions of universe expansion phenomenons.
- Steady State Model, which proposed continuous creations without metric expansions unlike universe expansion phenomenons.
- Oscillating Universe Model, which includes contraction phases absent in observed universe expansion phenomenons.
