Theoretically the coldest place in the universe would be a perfect vacuum as no matter = no temperature. Following this line of reasoning if you divide space down into small enough chunks there are infinitely many "places" around your head at absolute zero right now (and of course places at incredibly high temperaures). I guess this depends on wether space is quantised and I dont know if it is as I'm not a physicist.

But to be careful we have to define 'temperature'.
If temperature is a measure of energy in one form or another, even vacuum has temperature.
A perfect vaccuum surrounded by a barrier impervious to electromagnetic radiation = absolute zero?
Although I am thinking that if there is no matter and no energy there then asking what the temperature is is irrelevant as there is nothing to have temperature.
Its a bit like saying wow! I have the most infinitely small cat in the world - when you dont have a cat....mmmm

Drake states the probablility and hence how many scientific well developed civilisations there is in the Universe. Another factor and we get the number of intelligent technological civilisations *with* a laboratory producing Einstein Bose condensate. (What will they call the matter?)
Nature itself can't produce EB condencsate, right? Not even God himself? So this is a invention of man, and man alone, isn't it? As far we know it, of course...
