We consider a box of gas filled with different groups of matter that absorb photons primarily in different and mostly distinct frequency ranges. As a group that absorbs primarily high frequency photons emits blackbody radiation, some photons with frequencies too low to be reabsorbed efficiently by that group are readily absorbed by a group that favours such low frequency photons. This causes the high frequency group to cool and the low frequency group to heat up and the high frequency group to cool down as energy is transferred between the groups. If an infinite ladder of such groups exists in an infinite box, then this process would cycle eternally with each group periodically cooling and reheating as a given group sheds low frequency photons to lower groups while cooling and higher energy groups dump photons into it, causing it to reheat. A cosmology for this scenario is then explored and compared quantitatively to measured data.
