I agree. > >Photons having a temperature!?!? Really low temperature ones are called radio waves. :) > >Can the temperature of a photon be measured? > >If the sun was cold but emitted the same amount of light, would it heat us >less? That would depend on how close we were. > >If this is so, then could you use light as a heat sink? It already is. The Earth radiates lots of energy away into outer space every day. [snip] IMO every monochromatic laser should count as a BE condensate, and I suspect that what they have in fact created is a dye laser. Furthermore, I suspect that they will have great difficulty finding mirrors for x-rays. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/Project.html
