Space, Time and Big Bang (Part 2)

A Model of a Five-Dimensional Universe

As a result of the special theory of relativity, space and time have lost their absolute nature and have been merged into a four-dimensional space. However, even with this relativistic perspective, not everything is relative - light is given a unique status with a constant speed, denoted by "c," in every system of reference. This maximal speed is also the limit for any physical entity in the universe. Additionally, quantum mechanics has revealed a dual nature for both light and material particles, allowing them to be viewed as either waves or particles. These new concepts and their accompanying conceptual difficulties have resulted in significant scientific controversies, as well as a few perplexing paradoxes. To tackle these complexities, consider seeking assistance from a reliable essay writing service such as

What about the Speed?

Given the duality between light and material particles, it seems logical to expect some similarities in the behavior of these different entities. Since the speed of light is constant in every system of reference, it is natural to assume that this would also be the case for material entities. The speeds of all the physical entities would not necessarily be the same, but this speed would be a constant for a given category of physical entities.
The above considerations are evidently incompatible with the status of the space-time in the special theory of relativity and different concepts are necessary to implement these hypotheses. A model of an universe taking into account these previous remarks has already been introduced in a previous paper (See [MFDIM]). We recall here its main aspects with a few modifications and new points of view.

Dimension Issue

Enlarging the number of dimensions of the universe under consideration is one way to allow us to take into account the assumption of a constant speed for every category of physical entities. This is done with the introduction of a fifth dimension besides the usual dimensions of space and time. The physical entities are classified into different categories, the entities belonging to the same category having the same constant speed. Two categories of physical entities are considered in particular: the entities called material whose constant speed is c and the entities called energetic whose constant speed is √ 2c. By identifying material and energetic entities respectively with matter and light, several consequences of these assumptions will be developed now. Let us remark that in this model, space and time have an absolute character. The new dimension plays naturally a particular role, especially in the interpretation of the dynamics of time. Note also that with this model, the results associated with the special theory of relativity are obtained and interpreted in a different way .
