This thing is -270°C and is EVERYWHERE

Much of this has been comprehensively argued against by Sky Scholar. 
And why couldn’t it come from a magnitude of reality, far beyond the confines of our ability to discern the universe at the smallest of scales, known as the Planck ‘Limit’ There is no reason to not consider the universe existing nearly infinitely beyond our smallest and largest scales of discernible really. This larger reference frame could contain ‘octaves’ of systemic function and we are merely detecting the interfacing attributes of energy/scale boundaries.... 
I simply refuse to consider the ‘big bang’ or ‘infinity’ as real attributes of the universe. The meaningful definition of absolutes such as beginning and end, concerning the reality of universal existence is simply beyond our ability to conceive, or even imagine as the largest reference frame we are ‘theoretically’ capable of discerning is still hopelessly inadequate to make such postulations and present them as ‘fact’ Our singular point of perspective and understanding from within this reference frame does not help either.
