Your statements about tensor fields are uninformed or underinformed.
This statement has no relevance to the mathematics of tensor fields. It is a non-sequitor.
What “tight margins” are you talking about? Tensor mathematics, as separate from physics, imposes no physical limitations. It is only in application to specific physical phenomenon that “margins” may be discussed. And that is independent of tensor mathematics.
History, tight entry points, reported missing little girl.
As reported via a police report, data file, a girl went into her back yard, and went missing.
Her father heard the call and rushed out inback of the house, to be able to hear his daughter, but not to visually see her.
2. During a motion picture filming, as viewed from a rising platform, there was a faded mist, which encroached finback of the horse mounted actors.
The horses became upset.They had to quit filming right then and there.
The return when the film was developed, was a broad white mist, that was encroaching, inback of the actors and horses.
>* Look at time and space holes, as two little girls, using jump ropes, that are held in each hand.As a set these ropes are always in motion, however the widths of each rope can change its widths, at any time.
An odd analogy considering your statements. If you make the ribbon of rubber (or any other stretchy mateial that works like a spring) and stretch it you can’t explain what happens to the ribbon without reference to a tensor analysis.
The ribbon starts as a wide band and when it is stretched it becomes a narrow band and it heats up. Remove the strain and it returns to its original wide band and original length (well almost) - and cools off.
You have stress, strain and a thermal reaction going on with your ribbon.
