A potential is not a boundary ( to find the

electric field=gradient of a potential)

If you mean that ether is a marginal property of space, then let me disagree with you here. Take, for example, Minkowski space and fill it with ether in the form of a unit (in the sense of the Minkowski metric) vector field of velocities of ether particles. What is marginal here in relation to Minkowski space?

Space, particle, boundaries, ether. How are these entities related? I can only say that on the one hand, a space that has no boundaries can be limited (for example, an infinite irrational winding of a torus), and on the other hand, if the boundary is a feature of the vector field of the ether, in which the vector field is compactified, then a point particle can have boundaries. In addition, it was high time to return the ether to modern physics. Here is my attempt to do it

Research Proposal MATHEMATICAL NOTES ON THE NATURE OF THINGS

The thread question “What are the marginal properties of a space ?” really is rather questionable. Space and time in Matter compose Matter’s fundamentally absolute, fundamentally flat, fundamentally continuous, and fundamentally “Cartesian”, (at least) [4+4+1]4D spacetime with metrics (at least) (cτ,X,Y,Z, g,w,e,s,ct),

- where at least 4 cτ,X,Y,Z space dimensions and the time ct-dimension, besides that are continuous, are also fundamentally infinite; and so, say, in the spacetime above infinite “number” of other “Matters”, i.e. informational systems that have identical with Matter design, i.e. have the same as Matter’s one ultimate base/ Matter’s “ether” – the (at least) [4+4+1]4D dense lattice of primary elementary logical structures – (at least) [4+4+1]4D binary reversible fundamental logical elements [FLE], can be placed on infinite distances.

That’s all, the spacetime has only one property – to be an infinite continuous “empty container”, where everything in Matter and Matter as a whole, exists and constantly evolves, fundamentally by no means affecting/impacting at that on the space/time/spacetime, and the spacetime fundamentally by no means affect/impact on anything in Matter.

More about what are the fundamental phenomena/notions “Space”, “Time”, “Matter”, and not only, why Matter is as it is, including why Matter’s spacetime is as it is above, what are fundamental Gravity, Electric, Nuclear Nature forces and what are the Forces fields, see the Shevchenko-Tokarevsky’s Planck scale informational physical model, 3 main papers are
