罗时徐Four-dimensional space is a mathematical concept, which was put forward by German physicists and mathematicians. The fourth dimension of the four dimensional space is the space dimension with the same property as xv. It must have length, width, thickness and duration, which is the sum of three dimensional space and time

俞永清The four dimensions typically refer to the dimensions of space and time in physics. The three dimensions of space are length, width, and height, while the fourth dimension is time. Together, they make up the fabric of the universe and everything within it. Some theories suggest that there may be additional dimensions beyond these four, but they have not been directly observed or proven yet. -

赵宸Four dimensions, referring to the four dimensions, are a spatial concept. In physics, dimensions are used to describe the number of spatiotemporal coordinates. By applying dimensional analogies, people can infer that people in four-dimensional space should have similar magical abilities from our three-dimensional perspective.

路仁添Four dimensional space, also called "Euclidean four dimensional space", is standard Euclidean space. It's a mathematical concept that can be extended to n dimensions; The fourth dimension of four dimensional space refers to the space dimension that is identical with x, y, and z. In physics and mathematics, a sequence of n numbers can be understood as positions in an n-dimensional space. When n=4, the set of all such positions is called a four-dimensional space. The four dimensional space is different from the three dimensional space that people live in, because there is an extra dimension.
