→Starlight Problem for the Big Bang Theory
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>

{{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" />}}

However this problem ignores the current measurements of fluctuations in the cosmic microwave background<ref>http://map.gsfc.nasa.gov/m_uni/uni_101Flucts.html</ref>, and also fails to take into account the expansion of the universe throughout the course of its lifetime.
The fluctuations indicate the density distribution of the universe at the time of the formation of the background, which has been redshifted greatly due to the expansion of the universe pulling it apart. Over the course of the last 14 billion years, this expansion has relegated the CMB to nearly uniform microwave frequencies.
