It would appear that this may be simpler than one might think, if I may give an analogy:

Take an ellipse {d} and places within ellipse {d} a fixed point {a} that is not in its center but grossly offset, in where its radius to the outer edge of the ellipse is never equal. Then select a point along the outer edge, circumference, of the ellipse, where the radius is at its shortest point {b}. Then draw a circle {c} using the mid-point of this shortest radius as its center, that the circle {c} touches point {a} and point {b}. Assume that circle {c} is attached, to point {a} and to point {b}. Now imagine as point {b} moves in either a clockwise or counter clockwise, selecting one direction, the diameter of the circle {c} is elongated, as it travels around the circumference of the ellipse. As the diameter of circle {c} gets longer, the viewed shape of the circle becomes ellipsoidal, where the volume of the ellipsoidal-circle {c} decreases from the volume of the original circle {c}. Assume that the volume of circle {c} displaces the volume of ellipse {d}, and as the volume in ellipsoidal-circle {c} decreases, the volume of ellipse {d} increased to its maximum where the diameter of the ellipsoidal-circle {c} maximizes. As the ellipsoidal-circle {c} travels around the circumference of the ellipse {d}, it produces a respiration like action between the volumes of {d} and {c}.

Depending on how many of these ellipses you place in a master type ellipse, much like the way the Mazda Rotary Engine functions, the volumes change but are equalized within the master ellipse or bubble.

Assume that the dark matter in space functions as the opposing volume within visible space.

Could this scenario explain Space Respiration?

P.S.: In the analogy above keep in mind that this is just a two dimensional aspect of a pseudo definition of space respiration but could be applied to three dimensional aspect, possibly more. In addition, keep in mind that the mid-point of ellipsoidal-circle {c} maximum diameter, the point where this occurs is not opposite (in relation to the fixed point {a} and the beginning, or minimal radius point of circle {c}) in that because of the gross offset of point {a} there is angel between the minimal and maximum diameters using point {a} as the fulcrum point.

Sorry for having to edit this post so much but for some reason some symbol letter combinations have a tendency to change overnight?
