Definition of Fourth Dimension

The things of reality that surround us have width, height and thickness, which form three structures or dimensions. Some physicists consider that there are more than three dimensions, probably four or more.

Our brain is not designed to understand how something more than three dimensions would be perceived.

The dimension more primary would be a simple point in space. If this point is constantly repeated, a line is created, which constitutes the first dimension. The line repeated many times becomes a plane, that is, something in two dimensions.

With a combined and multiplied plane figure it is possible to create something in three dimensions, for example a cube.

What would happen if we placed something in three dimensions on itself and in a multiplied way? The answer to this question refers to the fourth dimension. For theoretical physicists it would be a new world, probably made up of multiuniverses or parallel universes.

A reality that goes beyond what we know

The circles, squares, and triangles are figures planes that have two dimensions, length and width. In a hypothetical flat world, we could deal with ideas like left and right, back and forth, but we couldn't understand the difference between up and down.

If we incorporate the idea of ​​height into the flat world, we obtain geometric figures three-dimensional. We can affirm that our mind it is trapped in three-dimensional space.

However, it is possible to imagine a structure of reality that goes beyond the three existing dimensions.

It is something that goes beyond experience sensitive and has not yet been discovered or conclusively proven.

The physical Theoretical handles the hypothesis of a fourth dimension but it is not feasible to specify what it consists of.

Einstein's theories tried to shed some light

Scientist Albert Einstein claimed that the idea of ​​time is what constitutes the fourth dimension. Thus, the movements that we know go from top to bottom, right and left or front and back.

For Einstein, time provides an additional dimension. In the theory From special relativity it is stated that three-dimensional reality is associated with the notion of time. This implies that space and time are not absolute magnitudes but actually depend on the position from a hypothetical observer.
