What is the point arguing with you when you dishonestly attribute things to me repeatedly? My stand is and was since post#5 that reduction in temperature on account of expansion is explained by the thermodynamic entropy concept (constancy of VT^3 ( not by CMBR red shift). I never said that expansion will not result into drop in temperature. Even otherwise it is very coomplex when we consider the temperature now and continued expansion as the universe is no longer a black body. CMBR spectrum that is BB specttum at 2.7K peak is actually observational evidence of reduction in temperature. Now stop this dishonest trolling, you have contributed nothing to this thread you are only taking shelter in other posters argument sometimes exchemists and sometimes DaveCs. I see not even an iota of hint that you understand this level of physics. Stop it and please desist from infracting me on frivolous grounds. You have done that in past even while being in thick of nasty arguments.
