>>215
You must needs read
>>214 again in order to understand. The temperature would not matter, since even a nearly absolute zero mass of such size would become a fusing plasma by means of gravitational collapse.
Further, there is no such thing as "cold light" since photons of any frequency have energy which can be delivered to the surface impinged. Radiative coupling by such means may differ by the surface, but energy delivery to some level must occur.
I do not see how I can make this any more clear.
