Dimensionality is not a box checked by how much space a system occupies; it is a living field that expands as connections, platforms, and lines of flight proliferate. If we treat dimensions as emergent degrees of freedom created by relations, the rhizome’s in-between becomes a productive engine rather than a mere backdrop.
- New empirical evidence suggests dimensionality is best read as a dynamic resource, not a static coordinate system. In brain network science, cognitive tasks recruit high-dimensional neural trajectories that reconfigure across contexts, signaling that functional dimensionality expands with demand rather than staying fixed. See Bassett and Sporns, “Network Neuroscience” for a synthesis of how flexible, multi-scale connections support richer state spaces than a single trajectory might imply.

- Topological data analysis (TDA) provides a concrete method to detect dimensionality that is not tied to a pre-set grid. Data from complex systems often reveal persistent features across scales, indicating multiple coexisting dimensions of structure and process. Carlsson’s foundational work on topology and data frames dimensionality as a shape that resists reduction to one axis. [Topology and data](https://en.wikipedia.org/wiki/Topological_data_analysis)
- Real-world networks increasingly operate as multiplex or multilayer fabrics: the same set of nodes connected through diverse modalities (social, economic, digital, ecological) generate a dimensionality that grows with each new layer. Kivelä and colleagues’ work on Multilayer Networks shows how cross-layer interactions create new degrees of freedom, enabling phenomena that no single-layer graph could capture.

- An expansive view of dimensionality also explains resilience in systems that routinely reinvent themselves. When a new platform, policy, or collaboration arises, the system does not simply add a node; it re-weights and re-zeros its entire connective fabric, effectively re-sculpting dimensions in situ. The rhizome—through lines of flight—maps these reconfigurations as ongoing, open-ended processes rather than settled coordinates.

- Novel angles to sharpen the argument:
- Dimensionality as a multiplex potential: each new layer or modality multiplies the space of possible trajectories, not because space is larger, but because the rules for interaction become richer.
- Dimensionality as governance: leadership, policy design, and engineering benefit from recognizing emergent dimensions—aligning incentives, data streams, and cross-disciplinary collaborations can unlock new lines of flight.
- Dimensionality as measure: use entropy rates, joint manifold embeddings, or persistent homology across layers to quantify how many independent directions of variation a system actually sustains at a given moment.
- Implications for theory and practice: modeling should prioritize open, adaptable mappings over fixed tracings; design should cultivate platforms that support cross-dimensional connectivity; and analysis should seek the “dimensions” that emerge when a system is asked to grow in new directions.
In short, dimensionality as emergent multiplicity gives us a robust vocabulary for understanding how real systems innovate, adapt, and endure. It reframes the in-between as the central site of creative power, precisely where rhizomatic connectivity does its most transformative work.
