  The four dimensional space is different from the three dimensional space that people live in, because there is an extra dimension. Through the evolution of one-dimensional, two-dimensional and three-dimensional space, people have put forward some conjectures about four-dimensional space. Although these conjectures are not proven right now, many scientific theories begin with conjectures. Nowadays, scientific theories are generally based on the summary law of phenomena, and there is not enough accurate and clear understanding of the phenomenon of four-dimensional space, or when we see this phenomenon, we do not think that it is caused by four-dimensional space. Of course, it is also possible to define the topological space of points, lines and surfaces as the fourth, fifth, sixth and NTH dimensions. This is easy to achieve in mathematical formula reasoning, but it is difficult to correspond and imagine in reality. However, when people refer to "four-dimensional space", they often confuse it with the "four-dimensional spacetime" (called "Minkowski space") mentioned by Einstein in his theory of relativity.

  The concept of time travel is made possible through the manipulation of the fourth dimension, which is described as time itself. The three dimensions of space - length, width, and height - are familiar to us, but Wells introduces time as a fourth dimension that can be traversed using the machine invented by his protagonist.

  
  

  In the novel, the Time Traveler explains that the fourth dimension is not something that can be easily grasped or visualized, but it is essential for understanding how time travel works. He compares the three spatial dimensions to the three dimensions of a solid object, and suggests that the fourth dimension is like a line that passes through all three dimensions, allowing for movement through time.

  
  

  The Time Traveler also describes how the fourth dimension is related to the concept of time as a continuum, where events occur in a linear sequence. By moving along the fourth dimension, he can travel to different points in time, just as he can move to different points in space by traversing the three spatial dimensions.

  
  

  In the context of "The Time Machine," the four dimensions are used to explore the concept of time travel and its implications for human society and the future of civilization. The novel raises questions about the nature of time, the consequences of altering history, and the responsibilities that come with the ability to travel through time.

  Four-dimensional space-time and physics

  Space-time continuum: In physics, four-dimensional space-time is one of the fundamental concepts of relativity. Einstein's general theory of relativity combines the three dimensions of space and time into a unified four-dimensional spacetime in which the laws of physics are consistent and locally invariant. This theory is crucial to understanding the large-scale structure of the universe and gravity.

  Momentum space: In particle physics, momentum space is an abstract space that differs from regular four-dimensional spacetime by using the three components of energy and momentum to describe particles. This provides an important tool for understanding particle interactions and particle dynamics.

  The " four dimensions " typically refer to length,width, height, and time. These are the basicconcepts used in physics to describe objects andphenomena.In different contexts ," four dimensions" may have other meanings , such as in psychology,philosophy, or mathematics, where they are appliedand interpreted differently . In physics, particularlywithin the framework of three - dimensional spaceplus time as the fourth dimension,these fourdimensions are used to describe the position andmotion of an object.For instance, when describingthe movement of an object from one point toanother , it is necessary to indicate not only itsposition in terms of length, width , and height butalso to consider the time factor, that is , the timetaken for the object to move.

  A four-dimensional space, also called a "Euclidean four-dimensional space", is a standard Euclidean space. It's a mathematical concept that can be extended to n dimensions; The fourth dimension of the four-dimensional space refers to the spatial dimension of the same nature as x, y, and z. In physics and mathematics, a sequence of n numbers can be understood as a position in an n-dimensional space. When n=4, the set of all such locations 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. Through the evolution of one-dimensional, two-dimensional and three-dimensional space, people have put forward some conjectures about four-dimensional space. Although these conjectures are not proven right now, many scientific theories begin with conjectures. Nowadays, scientific theories are generally based on the summary law of phenomena, and there is not enough accurate and clear understanding of the phenomenon of four-dimensional space, or when we see this phenomenon, we do not think that it is caused by four-dimensional space.
