Kelvin is a measurement of temperature, absolute zero. Not even sub atomic particles move at absolute zero(Kelvin). Any temperature above absolute zero would generate heat due to the movement within a molecule.
@DrWatson Absolute 0 on the Kelvin scale defines the maximum known limit of cold. All molecular, perhaps even atomic motion stops. Mathematically, negative numbers on this scale could be computed. Could an alternative universe exist in which these are real numbers and what properties would materials have in that universe?
@pdockal it's more a study of absolutes. Zero Kelvin describes our current understanding of a physical universe. Could there exist a negative Kelvin value in an alternate universe or is it along the lines of being at the North pole and trying to go more North? Could there exist a state where you could go more North in another dimension for that matter?
@pdockal it was kinda conceptual and open ended sort of thing. you know like when it says, "this page intentionally left blank" I mean, why not just put some artwork or a quiz in that space instead of wasting it? but I guess that's going to have to wait for a different post!
@DDonde Imagine it mathematically, much like calculations for time the sign does not affect the equation even though there is no observed occurrence in our universe.
