What does expansion of the universe mean? - Definitions.net
The expansion of the universe is the increase in distance between any two given gravitationally unbound parts of the observable universe with time. It is an intrinsic expansion whereby the scale of space itself changes. The universe does not expand "into" anything and does not require space to exist … See more In 1912, Vesto Slipher discovered that light from remote galaxies was redshifted, which was later interpreted as galaxies receding from the Earth. In 1922, Alexander Friedmann used Einstein field equations to provide theoretical … See more To understand the metric expansion of the universe, it is helpful to discuss briefly what a metric is, and how metric expansion works. A metric defines the concept of distance, by stating in mathematical terms how distances between … See more Hubble's law The metric expansion of space is a feature of many solutions to the Einstein field equations of general relativity, such as the Cosmological … See more • Comoving and proper distances See more The modern explanation for the metric expansion of space was proposed by physicist Alan Guth in 1979 while investigating the problem of why no magnetic monopoles are … See more Measurement of expansion and change of rate of expansion In principle, the expansion of the universe could be measured by taking a standard ruler and measuring the distance between two cosmologically distant points, waiting a certain time, and … See more Theoretical cosmologists developing models of the universe have drawn upon a small number of reasonable assumptions in their work.

Some insight into the expansion can be obtained from a Newtonian expansion model which leads to a simplified version of the Friedmann equation. It relates the proper distance (which can change over time, unlike the comoving distance which is constant and set to today's distance) between a pair of objects, e.g. two galaxy clusters, moving with the Hubble flow in an expanding or contracting FLRW universe at any arbitrary time to their distance at some reference time .
