# 4Th Dimension Is Time

Einstein used time as the **fourth dimension** to describe a coordinate system called spacetime. Einstein’s dominant view of physics for 106 years was that time served as the fourth dimension of space, an arena represented by **4D Minkowski space-time**. Herman Minkowski’s world overcame the problems associated with traditional absolute space and time cosmology by using a universe with three dimensions of space and a dimension of time.

From a physical perspective,** Einstein’s special theory of relativity** suggests that there is no connection between space and time, that they are a continuum of three spatial dimensions and one temporal dimension. They cannot be treated as interconnected, because the movement of one affects the movement of the other, but there are other properties inherent in space-time.

One could say that we live in a four-dimensional universe defined by the structure of space-time and not a three-dimensional universe because we have three spatial and one temporal dimensions, but these units can not be separated from each other, which is true. Time exists in both dimensions, and objects cross time in a similar way that objects in other three-dimensional humans are able to move through time in one direction or another. When we see objects in the four-dimensional space-time world, the line between them resembles a spaghetti-like line that extends from the past to the future, indicating the spatial position of the object at that time.

I see four-dimensional space as the space between our three-dimensional space and an additional dimension. As 3D beings, we experience the surface of a **4D ball**, while flatlanders experience two dimensions in their space and you and I are three-dimensionally curved. Three-dimensional creatures have lengths, widths, and heights, but humans are unable to see the fourth dimension because our physical world is built from these three-dimensional dimensions.

RenÃ© Descartes (1596-1650) imagined three dimensions of space and a separate dimension, time, in the 17th century, to determine the position of objects in physical space. Three-dimensional space is the simplest possible abstraction of observation. Since only three numbers are needed to describe the size and location of objects in the daily world, they are called dimensions. As mentioned above, three dimensions can be used to determine the position and movement of objects in space (left, right, up and down), while the time dimension locates their position in time.

By adding a time dimension to three-dimensional space, Herman Minkowski specified an alternative to perpendicularity, hyperbolic orthogonality. Lagrange wrote his **Mecanique Analytique**, published in 1788, based on works from 1755 on the mechanics of seeing and working in four-dimensional space and in three dimensions of space.

Time is the best dimension of space, because no matter how much you increase out of space, you always move forward or backward in time. There is time dilation, but not in the sense that time is the fourth dimension in which space expands as a result of the slowdown in clock speed, he explained. We need a time dimension that is inextricably linked to space so that physics can work as it does.

Sorli and Fiscaletti argue in their paper that the concept of special relativity is sound, but the introduction of** 4D** Minkowski space-time has created a centuries-old misunderstanding of the time as the fourth dimension of space, which lacks experimental support. Equating time with the fourth dimension is only one example of how the fourth dimension is positioned in relation to the first [3]. In a new study, they show that two phenomena, in particular relativity, can only be described in the context of 3D space, and that time is a quantity with which changes in the photon movement can be measured in this space.

Less than three years after Einstein presented his special theory of relativity, his former professor Hermann Minkowski demonstrated that space and time are united by a brilliant argument.

To help you think about how space in four dimensions curves, visit the lowlands, a two-dimensional world full of square, triangular and circular beings. As we will see, adding a dimension to space in order to form space-time is nothing mysterious.

His analogy in one of the higher dimensions, a marble stuck in a three-dimensional box can be lifted into a new three-dimensional space and when moved to the new space the original three-dimensional space sinks into the box. The two-dimensional analog image, a cube, is created by dragging a one-dimensional distance interval l into the second dimension. We can describe four points in the 4-dimensional space as four numbers : x, y, z, w (violette), where w is the angle of a right angle to another region ; in other words, we can imagine 4 squeezed dimensions as if they were three.

The fourth dimension is an abstract concept that is used in physics to determine if possible how non-Euclidean space and time can be quantified. Although published a full decade before Einstein’s theory of relativity, relativity treats time as a fourth dimension independently of the three dimensions of space much as Einstein conceived it in physics. The reason for this is to limit our understanding of the high-dimensional geometry of space: 3 dimensions are special in that they make it the only possible number of dimensions in space.

To locate the same latitude and longitude, you need to have the same two-dimensional coordinates, but not the same exact location; you need three independent pieces of information to determine your place in space.

In four-dimensional space, nodes consisting of curves can loosen and move in the fourth direction of a 2D surface to form non-trivial, non-self-overlapping nodes in four-dimensional space. We can lift objects of the third dimension out of the original two-dimensional spaces and adopt the colors blue, green and red.
