柳玮佳Four-dimensional space is a mathematical conceptwhich can be extended to N-dimensionin which thefourth dimension of four-dimensional space refersto thespace dimension of the same nature as xvand it must have LengthBreadthThicknessand-Duration A total consisting of three-dimensional space and time This concept was put forward by Germanmathematician and physicist.

唐雨静Four dimensions, that is, four dimensions, is a spatial concept. In physics, dimensions are used to describe the number of space-time coordinates, that is, four dimensions, which are composed of countless three dimensions, and three dimensions are composed of countless two dimensions. The composition of other high dimensions is inferred in this way, and dimensions above three dimensions are collectively called high dimensions.

SpriteFour-dimensional space is a concept of time and space. In short,any space with four dimensions can be called "four dimensions". However, most of the "four-dimensional space" mentioned in daily life refers to the concept of "four-dimensional space-time" mentioned by Einstein in his general relativity and special relativity. According to Einstein's concept, our universe is made up of time and space. The relationship between space and time is that a timeline is added to the three axes that are longer, wider and higher than the ordinary three-dimensional space in the space structure, and the axis of time is an axis of virtual value.

徐中一They can only see your mapping in two-dimensional space, that is, your shadow, but cannot see you personally. Similarly, people in three-dimensional space cannot "see" and understand four-dimensional life forms, commonly known as "ghosts", "souls", "aliens", "demons", "angels", "gods", and so on. At most, they can only briefly see their mapping in three-dimensional space, which is like we cannot see a complete mosaic but can see its mapping cube in three-dimensional space.
