Exploration of one-dimensional space and its nature
With the deepening and consolidation of three-dimensional space, the concept of three-dimensional space has been deeply rooted. Of course, there are also a few pioneering scholars with pioneering spirit, on the basis of three-dimensional space, put forward the hypothesis of four-dimensional space, or even ten or eleven dimensional space, and carried out mathematical modeling, which looks very advanced.
The dimension of the actual space, it's not that complicated. Space is essentially one-dimensional. We prepare a three-dimensional coordinate system drawn by Einstein: the X axis, the Y axis, and the Z axis.
And then we put the X axis, the Y axis, and the Z axis in any position, or in any position, and we find that we can still use this coordinate system to study the space problem without any problem. Does that give you an idea?
I get the idea that the X axis, the Y axis and the Z axis are equivalent. If they're equivalent, why do I have three axes? I just have one axis. Some people say, how can an axis show a space? This is actually very simple: go through any point in space, with any length as the ball. Perfect representation of space! Moreover, this "sphere space" is more real and realistic than the space of the square up and down. The quadripartite space up and down it's actually a gravitational taper space so it has up and down, but when you look at the free space in the vast universe away from the celestial bodies, where do you find the quadripartite? Up and down are even less to speak of.
One dimensional space, one point coordinate system. Everything in the universe can start at this point, get its coordinates, in which direction? How far is a line across? In the entire universe, everything can be located in a single, exact position through this coordinate system.
One has to question this point coordinate system: Isn't there an infinite number of points and lines? More verbose than three dimensions. The concept of point coordinate system established here is not for the convenience of research, but to further explore the nature of space. Of course, there is a willingness to explore the problem in depth from the point coordinate system.
Again, in three dimensions, the three axes of the coordinate system are equivalent, and completely equivalent! Raise your hand if you agree!
To rise to philosophy, we often speak of length, distance, extending from the length of an object, and the length of the object from one end of the rigid (elastic) distance to the other. Then, using this concept of length, we measure the length, width and height of the universe.
Trivia: Why did I come up with the concept of "point coordinate system", one-dimensional universe? Mainly from the three-dimensional coordinate system, from the original point to draw the X axis, Y axis and Z axis, a three-dimensional space image out. If you think about it the other way around, you shrink from the X-axis to the origin, an infinitesimal concept origin, or you shrink from the Y-axis and the z-axis even (X→Y plane, Z→Y plane, X→Z plane) and the whole X→Y→Z space shrinks to the origin, an infinitesimal concept origin, and in fact the "infinitesimal concept origin from contraction" makes no difference. And this infinitesimal idea that the origin is essentially equivalent to space except for the size difference.
