...."Our understanding of zero is profound when you consider this fact: 
We don’t often, or perhaps ever, encounter zero in nature."....
LINK..." Nevertheless, zero doesn’t have to exist to be useful. In fact, we can 
use the concept of zero to derive all the other numbers in the universe."....
..."To calculate the slope of a single point, you usually need a point of comparison: 
rise over run.
 What Isaac Newton and Gottfried Leibniz discovered when they invented 
calculus is that calculating that slope at a single point involves 
getting even closer, closer, and closer — but never actually — dividing 
by zero.“All infinite processes [in math] pivot around, dance around, the notion of zero,” Robert Kaplan says. Whoa.".....

My i asks a question, what happens if the drop-in's { >< }    -----defines the sine-wave pattern { observed time /\/\/ } inside the toroidal tube----    from outer { positive } and inner { negative } --and diametrically  opposed---  geodesic curvatures as space, in the term space-time/
More specifically, my question to self is, if the sine-wave patterrning --inside the tube subsides{ retreats } into the two curvature surfaces, and those two curvatures expand create a larger, volumetric  space inside, what is in that space?
