Cold takes energy and time.Hot gives energy and time.
No. One is very warm relatively associated with one which is very very cold.I am perplexed by your logic.... look. Theories should tackle either problems known, or problems yet to be solved. Not by speculations and certainly not by models which permit the old saying ''if it is not broke, why fix it?''
i think, there is nothing like absolute hot or cold, it is more of theory and less practical.how cold or hot can be an object? it depends on chemical structure of material, each material can not achieve any temperature. ***at absolute cold time stands still*** at absolute cold, it is materiaL and surrondings which remain still, as there is no change, not the time, TIME IS CHANGE, IF THERE IS NO CHANGE IN UNIVERSE, THEN TIME IS INSIGNIFICANT.

Hot represents energy and time contraction.Quote from: Ęthelwulf on 24/04/2012 21:39:02No. One is very warm relatively associated with one which is very very cold.I am perplexed by your logic.... look.

Not by speculations and certainly not by models which permit the old saying ''if it is not broke, why fix it?''This thread arose in response to a another thread. What is the temperature inside a black hole. Some proposed it is near absolute hot, I proposed it is near absolute cold. This thread attempts to explain how two seemingly opposites can be the same thing.Yes, it is speculation in as much as it is not proven but time reversal does come within the laws of physics as we understand them.The physics of black-holes is fundamental to our understanding of the Universe and there is much we do not know. Debate is a means of reaching that goal.I understand your frustration, because if time reversal were to be a proven fact then your ideas of the non-existence of time would be thrown out of the window.
Time reversal might have significance for individual particles, but as far as the entire universe goes, the universe is asymmetric. If it was symmetric, we might expect things like a time reversal in physics... but as far as I understand physics, time reversal is a much abused concept. Such a symmetry is a simple mapping[tex]T:t \rightarrow -t[/tex]But the observable universe does not contain such a transformation, the universe is largely asymmetric due to the second law of thermodynamics.
