(Zero dimension

Space) is a dimensionless space, it is a space from which no data can be found, so it is a point.

Is there a zero-dimensional space?

What is the meaning of zero-dimensional space? Zero dimension: According to the general law of Chinese word formation, we can easily get the meaning of zero dimension, and the geometric concept of dimension is dimensionless.

One-dimensional space is the production of positive and negative matter, and the annihilation of positive and negative matter in zero-dimensional space disappears …

One-dimensional meaning

There are countless points on a straight line, which is actually a one-dimensional space. If there are "people" in one-dimensional space, their image is a point on a straight line. In fact, a point is also a one-dimensional space, but this one-dimensional space is infinitely small. Plants are typical creatures in one-dimensional space, and the growth of their branches and leaves is prolonged, that is, prolonged growth, so it can be concluded that plants are generally creatures in one-dimensional space!

two-dimensional space

It refers to a plane space consisting of only two elements: length and width (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 a three-dimensional space (three-dimensional space) in two dimensions.

three-dimensional space

Three-dimensional space (also known as three-dimensional, three-dimensional) can refer to the space composed of three dimensions: length, width and height in daily life. Moreover, the word "three-dimensional space" used in daily life often refers to three-dimensional Euclidean space. For a long time in history, three-dimensional space has been regarded as a mathematical model of the space in which we live. Physicists at that time thought that space was flat. Since the 20th century, the discovery of non-Euclidean geometry has made the nature of real space have other possibilities. The birth of the theory of relativity and its corresponding mathematical description: Minkowski regards time and space as a whole and a four-dimensional continuum. After the emergence of string theory, it is not enough to describe the real universe in three-dimensional space, but it needs to use a higher-dimensional mathematical model, such as ten dimensional space.

four-dimensional space

Four-dimensional space is a concept of time and space. Simply put, any four-dimensional space can be called "four-dimensional space". But the "four-dimensional space" mentioned in daily life mostly 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 time and space is one more time axis than the length, width and height of ordinary three-dimensional space, and this time axis is an imaginary axis.

five-dimensional space

Five-dimensional

Space, space is a set, the most basic element is a point, the set of points is a line and a surface, and the movement of three-dimensional body produces time, which is the best way for human beings to give four dimensions. Simply put, five dimensions are caused by four-dimensional motion. Assuming that the four-dimensional space can be folded in half, the so-called empty thing after folding will be filled with four-dimensional motion, then people may say that this will not affect the motion of time, that is, it will not change the four-dimensional motion. That's not true. Time is produced by three-dimensional motion. Since this is not a three-dimensional change, it makes time need to be shortened, so it is not five-dimensional, that is to say, that axis is speed.

According to Einstein's special theory of relativity, especially the statement that the clock is slow. When the speed of an object approaches the speed of light, the time around the object will slow down rapidly and the space will shrink rapidly. When the speed of an object is equal to the speed of light, time will stop and space will shrink to a point, which means the emergence of zero time and space. When the object moves faster than the speed of light, time will go backwards, which is called negative time; Space will correspondingly return to the past space, which is the so-called negative space. At this time, the object will enter negative space-time, that is, space-time reversal or space-time reversal, so that the object will realize teleportation, that is, instantaneous movement.

Hexagonal space

Whenever physicists add dimensions to the universe they design, they basically add dimensions to the space, so that objects in the space can move freely. But in fact, if the universe can have more dimensions, is it possible to add another time dimension?

Many physicists oppose this idea, because if there are more time dimensions in the universe, objects can travel through the known one-dimensional time with the help of other time dimensions, and then appear around us, and then appear on other planets hundreds of millions of light years away, which is equivalent to exceeding the limit of light speed and even realizing time travel back to the past. At least in our universe, time travel doesn't happen, so multidimensional time may be just an idea, not a reality.

But in 1995, American scientists put forward a theory called M theory, which unified all kinds of string theories at that time. In H theory, there can be two-dimensional time. However, scientists add that even if there is two-dimensional time in the universe, time travel cannot be realized in such a universe. In H theory, the universe is 1 1 dimension. Is it possible to have multidimensional time in a slightly lower dimensional space-time? Theoretically, if we add a time dimension to our four-dimensional space-time, we must also add a space dimension to balance the structure accordingly. The six-dimensional universe formed in this way is actually very similar to the four-dimensional universe we live in, except that in the six-dimensional world, there will be many projections of the four-dimensional universe, and the familiar physical laws are not applicable there.

seven dimensional space

The so-called seven-dimensional space is also based on superstring theory. According to physicists, there should be seven more dimensions. Although there are so many dimensions, these dimensions are invisible and rolled together by themselves, which is called compressed dimension. To understand this view, let's take ants as an example and expand our imagination. We can imagine rolling up the paper on which ants walk until it is rolled into a cylinder. If ants walk along the paper wall, they will finally return to the starting point, which is an example of compressed dimension. If you can take it away along the famous Mobius, the above phenomenon will also happen. Of course, it is three-dimensional, but if you follow it, you will always return to the starting point. Mobius belt is compressed from the perspective of dimension. According to physics, it has three dimensions, but whoever walks on it can only recognize one dimension. It's a bit like the person on the left: up or down, but never ending. If the ants don't walk along the curved wall of the paper tube, they will never return to the original starting point. This is an example of two dimensions (or the kind of dimensions we perceive). Go straight along it, and you can't go back to the original starting point.

Octuple space

Eight dimensions are more complicated. Now the accepted theory in physics is eight-dimensional space, which is divided into X dimension (the length of an object), Y dimension (the width of an object), Z dimension (the height of an object), time dimension, gravity dimension, electromagnetic force dimension, universal gravitation dimension and universal repulsion dimension. This theory was put forward by the German physicist Bakhard.

Heim was founded in 1957, and then he further developed and improved it, and got some new achievements, one of which was to summarize a series of equations for calculating the mass of basic particles. Few physicists can understand it, and it was later proved to be correct by experiments. Because most of his theories are published in German, most physicists think these arguments are obscure and puzzling, and Zhang Er and Monk are puzzled. 1980, Heim's theory aroused the Austrian physicist Walter.

Luescher's concern, after careful study, he made a detailed explanation of the theory, and further improved it, so there is today's recognized Heim-de Luescher space, which is an eight-dimensional cosmic space structure (we are now in this space).

Nine-dimensional space

When we break through the light speed barrier, we will enter four-dimensional space, and when the speed drops to zero, we will enter two-dimensional space. But in practice, we can't achieve it. When people travel by UFO, they are completely decomposed before approaching the speed of light. There is only one way to return time to zero when entering two-dimensional space, and that is to destroy one's own life and stop the movement of all physical media. Through the above analysis, we find that

The more we want to enter the high-dimensional space, the more difficult it is, which is interrelated with our existing scientific and technological strength. The higher the technical level, the higher the space will be. In the future, when humans try to enter the nine-dimensional space, they will find a unique scene.

ten dimensional space

The string itself is very simple, just a tiny line. Chords can be closed in a circle (closed chord) or opened like hair (open chord). A string can also be decomposed into smaller strings, and it can also collide with other strings to form a longer string. For example, an open string can be split into two small open strings; Can also form an open chord and a closed chord; A closed chord can be split into two small closed chords; The collision of two strings can produce two new strings.

But when a string moves in time and space, it is not so simple. The motion of a string is so complicated that its trajectory can no longer be accommodated in the three-dimensional space, and it must have a space as high as ten dimensions to satisfy its motion (ten dimensional space is the result of mathematical equation calculation). Just as human motion is too complicated to be completed in two-dimensional plane, it must be completed in three-dimensional space.

Eleven dimensions

After ten dimensional space of superstring theory, the ultrathin film theory in eleven-dimensional space is deduced.
