a PHD?? ha.. and you are not even aware that the cosmic background radiation is the same signal expected from free floating hydrogen gas at 2 degrees -3.7 degree Kelvin in free space... gesh... and space does not have temp... it has waves of energy in it... passing threw it. you do know how to use PV=NRT dont you? do you understand it? the problem i have found with most PHD's.. is they think they are so smart.. but unfortunately.. they are accustommed to having people teach them stuff.. rather than seeking it out for themselves.. and teaching themselves that which the schools and their biased views don't teach... -MT also you do know that all atoms emit photons relative to their temp?? dont you? its called infra-red... gesh... maybe you should of studied Chemistry.
