It is regularly stated by cosmologists that there is "nothing outside the universe". What is "nothing". Can one not define it as (1) timelessnes: i.e "nothing can change when there is nothing"; therefore "nothing" should (2) have zero entropy and thus zero temperature. A four-dimensional Euclidean space-time will have these properties because the time axis is perpendicular to the space axes. This implies that any differential within three-dimensional space with respect to time will have to be zero. Maybe our universe is flying apart to unbend space-time towards a state of zero entropy; as it had been before creation?
