i have read in some articles that when 0 Kelvin is achieved then particle movement within the cooled substance ceases. but my doubt is that einstein said that all objects have constant movement. this means that if the particles really stop then they will kind of stop in time because it is longer moving through space time. this i believe is not possible but am not sure of a reason. i think it may have to do with the frame of reference but cannot find a direct solution. can someone tell me a way to solve this paradox.
