can say that the spacetime sphere is a giant hollow string! On the level of Prior-Geometry there is NO SHAPE, there is only dynamic potency.
The basic equation is always correct, either it starts with 1 = 1, or 0 = 0, or ∞ = ∞ .
If we start with infinity (∞) as the basic value of spacetime, then:
∞ =∞
∞ = ∞ potency
∞ = ∞ + ∞ + ∞ + ∞ + ∞ + ∞ + ∞
∞ = ∞ + [restructured ∞] + [restructured ∞] + [restructured ∞] + ∞ + ∞ + ∞
∞ = ∞ + [(Active part F pelastrates Passive part G)] + [(Active part K pelastrates Passive part L)] + [(Active part V pelastrates Passive part W)] + ∞ + ∞ + ∞
∞ = ∞ + [Macro Quantum package G(f)] + [Micro Quantum package L(k)] + [Micro Quantum package W(v)] + ∞ + ∞ + ∞
Now millions of combinations are possible, just some examples:
1. The Active part F and/or the Passive part G of the [Macro Quantum package G(f)] can create new Quantum Micro packages inside itself (sub-sets) on any of it's boundaries.
2. The [Micro Quantum package] may penetrate the purple ∞ zone becoming: new Quantum package [ ∞ layer over [Micro Quantum package]]
3. [Micro Quantum package] can penetrate in the [Macro Quantum package]
As fact a combination of the String theory and Brane Theory, indeed :
∞ Membrane = ∞ strings + ∞ strings + ∞ strings + ∞ strings + ∞ strings + ∞ strings + ∞ strings
All those strings are parts of the membrane + they have automatically GRAVITY included.
Occam's razor applied: there is no need to create closed gravitational strings that float away from the brane.
The vibrations of strings depend from the vibrations of their local brane base (like the violin string is connected with the wooden violin body) and from the interactions they have with other single strings and with other Quantum packages (joined strings). So oscillations will be conducted by the brane + the strings + combination of strings which are resonant.
Occam's razor applied: there is no need to have open-end strings and we can drop the gluing problem.
