Four-dimensional space is a space-time concept. In short, anyone with four-dimensional space can be referred to as "four-dimensional space." However, the daily life of the reference to "four-dimensional space", most of them refer to Einstein in his "General Theory of Relativity" and "special relativity" in reference to a "four-dimensional space-time" concept. According to Einstein's concept, our universe is constituted by the time and space. The relationship between time and space, the structure in space three-dimensional space than the average length, width and height of the addition of the three axis of a timeline, but this time the axis is the axis of an imaginary value. According to Einstein's theory of relativity says: We live in the face of the three-dimensional space plus time constitute the so-called four-dimensional space. As we feel the time on earth is very slow, so it will not obviously felt the presence of four-dimensional space, but once boarded the spacecraft or to reach the universe, so their frame of reference where the speed faster or start near the beginning speed of light, we can find time to contrast changes. If you are close to the speed of light in the speed of the spacecraft in the navigation, your life on earth than the people for much longer. There is a potential place in the material the energy will change with the speed of change. So the time change and the speed of contrast material is the frame of reference of the. This is why it is four-dimensional space time one of the elements of the cause. [Edit this paragraph] resolution four-dimensional space】 What is a four-dimensional? Now the argument is three-dimensional space plus the dimension of time, constitute the so-called four-dimensional space. However, this view is a hit broken. Why? We can consider the two-dimensional. A two-dimensional biological (if any), they consider the so-called three-dimensional space of our three-dimensional absolute and different - they would time as the third dimension, because they can not feel the existence of that dimension. Similarly, we now also entered the errors, the time counted as the fourth dimension. We could see the four-dimensional biological time in promoting this idea, but also for us to sigh. Then the time count as one-dimensional? In my opinion, the time should be one-dimensional, that is, outside the dimensions of multidimensional biological itself plus one dimension to form the new N +1 dimensional space, and this will also help solve some problems for us, but also allows us to three-dimensional space compared to deepen understanding of higher dimensions. There is a newer concept, that all dimensions are constituted by the time, no time, no space, including the most basic one-dimensional space. This should be easy to understand, because there is no time, the existence of space itself has no meaning, because the space itself is indivisible whole. Why, then, a time to form different dimensions of space? Here, we can time can be decomposed as a constant. Time can be broken down, these words may be a bit difficult to understand. However, as long figured out reason is very simple. To understand this principle, we must first understand the two points. The first is the inseparability of space and time, it is estimated that we all know, left the room about the time, or leave the time to talk about space, are meaningless. The second point is the diversity of time, it might be a little trouble understanding them. In daily life, we are exposed to synthetic body time, which is the combination of the various points of time to form a total time system. Maybe you would think I was in sophistry, it is not. As long as you think from a different angle, a result may be formed by several different reasons. Take the campaign, we have observed are generally produced by several different sports a combination of a movement that co-movement. About time, we could think about. Time we see a combination, can be caused by the time the movement of objects, historical time (ie elapsed time) and some other time composition. The exercise time, we can also move up and down as the time from the left and right movements of the time and the time before and after exercise. Of course, the division is diverse, which constitute the diversity of time, as to how to divide, which would be by a different situation. Part of the time corresponding to a space. In the incomplete space, time played a decisive role.

维度（dimensionality），又称为维数，是数学中独立参数的数目。
在物理学和哲学的领域内，指独立的时空坐标的数目。0维是一个无限小的点，没有长度。1维是一条无限长的直线，只有长度。2维是一个平面，是由长度和宽度(或部分曲线)组成面积。3维是2维加上高度组成体积。
4维分为时间上和空间上的4维，人们说的4维通常是指关于物体在时间线上的转移。（4维准确来说有两种。1.四维时空，是指三维空间加一维时间。2.四维空间，只指四个维度的空间。）四维运动产生了五维。
从广义上讲：维度是事物“有联系”的抽象概念的数量，“有联系”的抽象概念指的是由多个抽象概念联系而成的抽象概念，和任何一个组成它的抽象概念都有联系，组成它的抽象概念的个数就是它变化的维度，如面积。此概念成立的基础是一切事物都有相对联系。
从哲学角度看，人们观察、思考与表述某事物的“思维角度”，简称“维度”。例如，人们观察与思考“月亮”这个事物，可以从月亮的“内容、时间、空间”三个思维角度去描述；也可以从月亮的“载体、能量、信息”三个思维角度去描述。
