Within the framework of the “202 base-2 notations” model, often associated with the 81018 project, Dperp (D_{perp}\) (perpendicular, or transverse) and Dpar (D_{par}\) (parallel, or longitudinal) dimensions can be related to the 202 base-2 notations. [1, 2]
The 202 base-2 notation model suggests that the entire universe, from the Planck scale (10-35 meters) to the current age of the universe (1026 meters), can be mapped by doubling Planck units approximately 202 times (2202). [1, 2]
Here is how Dperp and (Dpar} (often referring to dimensions in string theory or cosmological structure) relate to this model:
- Continuous Scaling: The model suggests that the 202 notations provide a continuous scaling framework, wherein the dimensions, or “notations,” act as steps of growth.
- Dperp \(D_{par}\) and Dpar \(D_{perp}\) within Notations: As the universe expands from the Planck scale to the 202nd notation, the parallel (longitudinal) dimension can be seen as the expansion of the notation itself (\(2^{N}\)), while \(D_{perp}\) (transverse) refers to the transverse dimensions at that specific scale.
- Dimensionality and Symmetry: The 202 notations suggest that the universe’s structure emerges from a symmetric, 4-dimensional Planck scale, with 201 subsequent doublings developing the structure of the observable universe.
- Geometric Embedding: The 202 doublings (notations) show how small-scale geometries can grow to define cosmic scales. [1, 2, 5]
The 202 notations map is not a standard model of cosmology, but a proposed framework 81018.com where Planck length time 2202 approximates the diameter of the observable universe (about 8.8x 1026 meters).
