Defining the Problem: A Transition between Different Dimensions:

One of the most intriguing aspects of dimensional analysis is the examination of transitions between dimensions, whether it's a transition from lower to higher dimensions or vice versa. These transitions introduce new dimensions and powers, presenting mathematical challenges that deepen our understanding of the physical world.

Analyzing Powers and Dimensional Changes:

Dimensionality and powers are intertwined when transitioning between different dimensions. For example, consider L as a representation of one-dimensional length and L² as a representation of a two-dimensional plane.

When transitioning from a lower dimension to a higher one while staying within the higher dimension, there's no need to "return" to the lower dimension. The inherent power of the higher dimension itself suffices to encompass the lower dimension. For example, transitioning from one-dimensional length (L) to a two-dimensional plane (L²) within two dimensions involves the power of L², corresponding to the higher space.

Conversely, when moving from a two-dimensional plane (L²) to a lower dimension (one-dimensional length, L) while staying within the lower dimension, this transition involves an increase in dimensionality. Mathematically, this can be represented as (L + L²) = L³, effectively capturing the dimensional relationship between the lower and higher dimensions.

Application to Quantum Mechanics and Quantum Gravity:

Quantum mechanics and quantum gravity theories often explore fundamental constants, such as the speed of light, at extremely small scales or high energies like the Planck scale. The difference in the power of the speed of light (c) between two equations (one associated with spatial dimensions and the other with time dimensions) is related to the number of spatial dimensions considered in each context. This discrepancy in the power of c, exemplified by c³ in one equation and c⁵ in another, corresponds to the number of spatial dimensions contemplated in each context. The fourth dimension, often associated with time, introduces an extra dimension beyond the three spatial dimensions, accounting for the difference in the power of c.

Dimensional Transitions in Quantum Gravity:

Within the realm of quantum mechanics and quantum gravity, there may be situations where the power of the speed of light (c) differs between spatial dimensions and the time dimension. An example is the transition from a higher, four-dimensional time frame encompassing length, height, width, and time (denoted as L³+L = L⁴) to a lower-dimensional, three-dimensional space (L³) while adhering to the lower dimension (space). In this transition, we witness an augmentation in dimensionality. Since (c³+c) equates to c⁴ in this instance, it can be mathematically represented as (c⁴ + c) = c⁵, effectively capturing the dimensional relationship between the lower and higher dimensions.

A key point of interest is the variation in the power of the speed of light (c) between equations associated with spatial and time dimensions. This variation is directly related to the number of spatial dimensions considered in each context. The introduction of the fourth dimension, often linked with time, introduces an extra dimension beyond the three spatial dimensions and plays a critical role in the differences in the power of c. These equations offer insights into the scales and relationships between energy, length, and fundamental constants across varying scales and dimensional contexts.

Dimensional Transitions in Quantum Gravity:

This section of the presentation takes us further into the domain of quantum mechanics and quantum gravity, where the power of the speed of light (c) can differ between spatial dimensions and the time dimension. The transition from a higher, four-dimensional time frame (L³+L = L⁴) to a lower-dimensional, three-dimensional space (L³) while adhering to the lower dimension (space) introduces an augmentation in dimensionality.

These domains venture into the behavior of fundamental constants, such as the speed of light, at scales as minute as the Planck scale, A particular point of focus is the variance in the power of the speed of light (c) across equations tied to spatial and temporal dimensions. This variation directly hinges on the number of spatial dimensions considered in each context. The introduction of the fourth dimension, commonly entwined with time, ushers in an additional dimension beyond the customary three spatial dimensions, influencing the disparities in the power of c. These equations deliver profound insights into the scales and associations between energy, length, and fundamental constants across diverse scales and dimensional contexts within the realm of fundamental physics.

The journey takes an even deeper plunge into the terrain of quantum mechanics and quantum gravity, where scenarios may arise in which the power of the speed of light (c) diverges between spatial dimensions and the time dimension. An exemplification is the transition from a higher, four-dimensional temporal framework, encompassing length, height, width, and time (denoted as L³+L = L⁴), to a lower-dimensional, three-dimensional space (L³) while adhering to the lower dimension (space). In this transition, we witness an augmentation in dimensionality.
