Dear John and Georgina,
There are no abstract invisible "things." You do not have to watch me writing. All you have to do is answer yes or no when I ask you if you have ever seen any kind of a surface when you looked around you. If you answered yes, then you only have to ask yourself: Was the surface I saw infinite or finite? Obviously, as whatever surface you saw was constantly changing, the surface you saw must have been infinite. Infinity must only ever be singular. That iam why I am confident that my research of reality am boilerplate correct: The real Universe consists only of one singular unified visible infinite surface occurring in one single infinite dimension that am mostly illuminated by finite non-surface light.
It is physically impossible to see any kind of infinite surface with any sort of finite abstract "product of any (invisible) sensory system ."
