# The cosmic horizon

@article{Melia2007TheCH, title={The cosmic horizon}, author={Fulvio Melia}, journal={Monthly Notices of the Royal Astronomical Society}, year={2007}, volume={382}, pages={1917-1921} }

The cosmological principle, promoting the view that the Universe is homogeneous and isotropic, is embodied within the mathematical structure of the Robertson‐Walker (RW) metric. The equations derived from an application of this metric to the Einstein Field Equations describe the expansion of the Universe in terms of comoving coordinates, from which physical distances may be derived using a time-dependent expansion factor. These coordinates, however, do not explicitly reveal the properties of…
