→Starlight Problem for the Big Bang Theory: Be more precise, and remove full stop to fix sentence flow.
Despite the use of the Starlight Problem in arguing against young-Earth creationism, the [[Big Bang Theory]] has its own light travel problem, known as the horizon problem.

The Big Bang model proposes that the temperature of the [[Cosmic Microwave Background]] (CMB) would have varied considerably from place to place early in the universe, yet because the speed at which this radiation can disperse from hotter to colder parts of the universe is limited by the speed of light, there has not been enough time for the radiation to even out, yet observations today show it to be extremely uniform.<ref name="Lisle">Lisle, 2003</ref> (though with some minor fluctuations <ref>[http://map.gsfc.nasa.gov/m_uni/uni_101Flucts.html Fluctuations in the Cosmic Microwave Background]</ref>).

{{QuoteBox|The problem is this: even assuming the big bang timescale, there has not been enough time for light to travel between widely separated regions of space. So, how can the different regions of the current CMB have such precisely uniform temperatures if they have never communicated with each other? This is a light-travel–time problem.<ref name="Lisle" />}}
