Dimensionalitetsreduksjon
Dimensionalite is a hypothetical scalar field proposed in some speculative approaches to quantum gravity and cosmology as an order parameter for the local effective dimensionality of spacetime. In models that allow the number of spacetime dimensions to vary with energy scale or region, dimensionalite provides a dynamical mechanism to describe such variation and to encode how dimensionality could influence physical laws.
In common formulations, the field φ representing dimensionalite couples to the spacetime metric and curvature through a
The concept remains speculative and is not part of established physics or supported by direct experimental
