SpaceTime Mathematics - Dimensions in Physics

SpaceTime Mathematics is an advanced scientific calculator for power users. It offers a wide variety of functions and enables 2D and 3D graphing.

Dimensions in physics

One of the most intriguing aspects of physics is that there are many theories that try to unify the four fundamental forces by introducing extra dimensions. Most notably, superstring theory requires 10 spacetime dimensions and originates from a more fundamental 11-dimensional theory tentatively called M-theory.

There are also many other theories that suggest that the universe is made up of multiple extra dimensions. These extra dimensions are referred to as hyperspace, and it is believed that they exist at extremely small scales where they are effectively invisible to current experiments.

Nevertheless, some of these theories still propose that we can see evidence for their existence. Several references to this idea can be found in literature, such as A Wrinkle in Time and The Boy Who Reversed Himself.

Timedimension

A temporal dimension is a dimension of time and is often referred to as the fourth spatial dimension. This dimension is perceived differently from the three spatial dimensions in that there is only one of it and that we cannot move freely in time but subjectively move in one direction.

In the presence of special relativity (SR), interactions are used to define points in a spacetime. This is a property that is at the heart of SR phenomenology and which makes this concept useful for explaining observable phenomena, such as the evaporation of virtual black holes. In DSR, however, this property is no longer valid: particles interact locally in a new noncommutative spacetime instead. This means that a number of possible footprints is no longer present in the interaction, which may be a major difference for phenomenological analyses.
