Space has background temperature to it from having its own density when void of matter and energy. If nothing existed at all then the heat and density of space would have to expand infinitely fast, and even if that was possible the temperature and density of space could always be less. So though you can measure infinity by large and small you can't have an infinite negative temperature or density or 'nothing at all' because there could always be something less.
