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 "outside" it. This … Visa mer 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 … Visa mer To understand the metric expansion of the universe, it is helpful to discuss briefly what a metric is, and how metric expansion works. A Visa mer Hubble's law The metric expansion of space is a feature of many solutions to the Einstein field equations Visa mer Theoretical cosmologists developing models of the universe have drawn upon a small number of reasonable assumptions in their work.
