Line 1: − + − The expansion rate of the universe can be calculated from the [[Hubble Constant]], which was verified using [[redshift]] measurements, the most current study found the universe to be approximately 156 billion light years wide <ref>Universe Measured: We're 156 Billion Light-years Wide! <i>Space.com</i> [http://www.space.com/scienceastronomy/mystery_monday_040524.html]</ref>.+ − The age of the universe is currently estimated to be 13.7 billion years, this means that space itself can expand faster than the speed of light. − Within our own galaxy, and even within our galaxy's [[local group]], the expansion of the universe can be factored out since gravity holds this superstructure together.+ − Parallax, spectroscopic (using redshift, which is still usable at even greater distances) and [[Cepheid]] measuring techniques can all be used within the local group which has been measured to be about 46 million light years in diameter. − −

The Starlight Problem is an argument in favour of a universe with a long history - many billions of years - as opposed to the six thousand year age many creationists interpret based on the Genesis narrative.

Given that the speed of light cannot possibly be exceeded - a conclusion of general relativity, and to which no exceptions have yet been found - the most distant visible objects cannot be further away than the distance light could travel since the universe was created. Thus, the distance to the furthest visible object can be used to establish a lower limit on the age of the universe.
Using parallax calculations, the milky way galaxy alone can be directly observed to have a diameter of approximately 80-100,000 light years. Calculations based on the observed brightness of supernovas of known energy output can determine the distance to more distant objects. The most distant object known is a star cluster approximately thirteen billion light-years distant, observed by the Hubble telescope using gravitational lensing<ref>http://news.bbc.co.uk/1/hi/sci/tech/3490657.stm</ref>.

Several solutions have been proposed by creationists to explain how a young universe may be reconciled with these observations. Some of these may be viewed on
