![]() ![]() Imagine the beings in a flat square at the bottom of the cube (2nd dimension). Since we are limited to a three-dimensional perspective, we cannot perceive it. What about four-dimensional cubes then? It would be a tesseract, four-dimensional analog or ‘shadow’ cube. Thus, the three-dimensional cube is in the world ‘over’ the two-dimensional square. The square would lie flat and could move just left, right, forward, and back. ![]() ![]() Simply put, in a flat concept, it can be said that space reality is a square, not a cube. But time has become a part of that system, in which it is presented as another dimension. It is real in that sense that it resembles the first three dimensions. With three dimensions the space is shown by coordinates, while the four dimensions of the time (t) are not displayed in that coordinate system with some angle (dimensional) that is constant or real. Four-dimensional space is space-time concept. The temporal relationship between the spatial structure of a regular three-dimensional space of length, width and height of three axes also added a date, but this time the axis value is a virtual axis. According to Einstein’s concept, our universe is composed of time and space. The three-dimensional space at each individual point is determined by three numbers corresponding to the distance from the reference point on each axis to the point of the cross-section with the given plane.Įver mentioned “four dimensions of space,” mainly refers to Einstein’s “general relativity theory” and “special relativity” in relation to the “four dimensional space-time” concept. The position of any point in the space is determined with respect to the three axis coordinates that have different numerical values in each given interval. The depth of this perception depends on the visual ability of world awareness and the ability to recognize three dimensions with the help of the senses. The perception of three-dimensional space is developed at a very early age and has a direct relationship to the coordination of human movements. It is called three-dimensional, because its description corresponds to three of the unit vectors, which are the length, width, and height direction. The three dimensional space is the geometric model of the world we live in. Evidence of the existence of the fourth dimension (4D) is problematic due to the fact that we cannot directly observe anything that is outside our three-dimensional space. But scientists have long assumed that there probably is a fourth spatial dimension that is beyond what we can experience or understand. The world we experience is composed of three-dimensional space – width, depth, and height, in addition to the temporal dimension of time. ![]()
