We can't get to absolute zero. This is fairly obvious, since extracting all the heat energy from matter requires a lower temperature reservoir into which it can be made to flow, i.e. you can only get to absolute zero if you can get to below absolute zero - which you can't, by definition! Most of the rest of your post seems to be word salad, so I cannot address it. However, among your various apparent misapprehensions, I will try to address two: Firstly, as Dave indicated earlier, temperature is only defined for bulk collections of matter in thermal equilibrium. In a non-equilibrium situation, or in the absence of matter, temperature has no meaning. It is thus not the case that all systems have a temperature. Secondly, absolute zero is not an arbitrary level. It is the temperature at which there is no heat energy left to extract from a body. P.S. this post of yours makes considerably less sense than your posts usually do. Is something wrong?
