2. Two-dimensional space: a plane space consisting of only two elements: width → horizontal line and height → vertical line (X axis and Y axis in geometry), which only extends in the plane. It is also a term in art. For example, painting is to express things in three-dimensional space in two-dimensional space.
3. Three-dimensional space: in daily life, it can refer to the space composed of three dimensions: length, width and height, that is, the space we can see and feel.
4. Four-dimensional space: First of all, the wrong statement is that "four-dimensional space is defined as three-dimensional space+time axis", while "three-dimensional space+time dimension" is another statement. Four-dimensional space refers to the standard Euclidean space.
5. Five-dimensional space: similar to wormholes, the curled time dimensions can be connected, but in the same meta-universe.
6. Six-dimensional space: multiverse, jumping between parallel timelines. Quantum theory supports six dimensions, and we can only see one of the results (five dimensions).
7. Seven-dimensional space: various possible sets of the universe, so a point in seven-dimensional space is all possible sets below six dimensions, which is infinite.
8. Eight-dimensional space: The explanation of eight dimensions is that this infinite possible state is also connected by a similar timeline, which is a continuous infinite possible different state. Go back to four-dimensional to three-dimensional, or line to point.
9. Nine-dimensional space: The existence of nine dimensions gives different information about the initial state of infinity in seven dimensions, such as the gravity of light beam and various constants. At this point, the point in seven of the nine dimensions can be explained in this way, giving the infinite possibility of creating an initial singularity, and the eight dimensions are infinite possible states at different times (if it can be called time). Nine dimensions are singularities with infinitely different initial states.
10, ten dimensional space: Ten-dimensional refers to the collection of infinite singularities with different initial states in nine dimensions as a point, so it includes all the singularities with different initial states, their development, their parallelism and all possible possibilities!
According to the understanding of string theory, we can know that our universe or all the above understandings are based on the basic particle state. Under string theory, this particle has strings, the most basic thing is strings, and the string membrane constitutes the basic particle, so all the above understandings add two dimensions from the bottom. Add two dimensions to all the above understandings in turn, and the total is * * * 12. That is to say, if string theory is accepted, there is 12 dimension; if not, 10 dimension is possible.
Extended data dimension summary:
To put it simply: n dimension is the space formed by n straight lines vertically.
Because humans can only understand three dimensions, the latter dimensions can be constructed by mathematical theory, but it is difficult to understand them carefully. In quantum mechanics, the membrane theory that is still being established holds that the universe is 1 1 dimension.
Cosmic philosophy on the dimension of the universe In reality, the universe is five-dimensional;
One-dimensional time, three-dimensional space and one-dimensional matter. * * * Five dimensions.
Mentally, it can be infinite, because the spirit is a thing in the past, where it can be unconstrained!
