In fact, the fourth dimension of space is not time

You are just thinking about the problem from the material level, but have you ever thought about what space is made of, even if there is nothing in this space, but this space still exists, space is made of a force, if one day, this force disappears, this space will also disappear, so there can be a large space in a very small thing, maybe this is not easy to understand but everything in the universe is supported by this force, but the ** of this force is something that continues to be studied, Everything in our lives is actually an interaction of forces, such as electricity. Light, etc., electricity, the movement of light, and ordinary motion are the same.

There is some truth, but it doesn't seem to be of much use.

There is a gap between imagination and reality.

On a macroscopic scale, reality is three-dimensional. This is an indelible fact.

String theory has to be 10 or 9 or 11 dimensions. is correct, so we have to interpret the other dimensions as too small to be detected by any experiment.

The reality is not like this, you say that this thing does not make any sense.

I'm really convinced. I always say that the space itself is a few dimensions and a few dimensions, and the facts that are already known do not matter at all. Any breakthrough in understanding is not to overturn previous facts, but to explain more facts without contradicting previous understandings.

You say it's 4-dimensional, but I can still say it's dimensional. Is it true that whoever of us is better at speaking?

The fact is: the macroscopic scale is 3 dimensions. What kind of spirit can also make a one-dimensional or something, get out of the way for me.

The so-called dimension that cannot be felt by people has a scale requirement, and it must be smaller than the smallest distance that can be detected now. For this kind of uncertain thing, no one knows how many dimensions it is. String theory says that it should be 9 dimensions, 10 dimensions, and 12 dimensions, which is the characteristic of its theory.

For other dimensions, the theory is not self-consistent. It doesn't make any sense for you to talk about 4 dimensions or anything here. Because your number is not given from any logic, but you take it for granted.

Wrong! There is a fatal limit to what you say! According to you, we live in three dimensions, and four dimensions are just a point for us, but are you really sure that we are living in three dimensions?

Just because you don't feel other dimensions, does it mean that we live in a three-dimensional space? You can't feel the atom, but it's there!

It's definitely not a time dimension, it's in one dimension, two dimensions, and three dimensions, time is independent and dimension-independent.

The term "four-dimensional space" mentioned in everyday life refers in most cases to the concept of "four-dimensional time-time", which Einstein mentioned in the general relative permeability theory and the special theory of relativity. According to Einstein's concept, our universe is made up of time and space. The spatiotemporal relationship is another timeline in the spatial structure, which is long, wide, and high beyond the three axes, and the timeline is an imaginary number.

These theories are used by scientists to study the universe. High, but only wool knows. The simple understanding of four-dimensional space is that it consists of 16 points, 32 lines, and 34 faces.

The relativity of time, such as the time it takes for the Earth to revolve around the Sun for one year, is defined as the movement of the Earth relative to the Sun. When determining the specific time, it is also necessary to take into account the ease of use, which is why there is practically no Martian year.

This caused a lot of buzz at the time, when Newton believed that Ethernet was the medium of light movement and that the space-time interval was absolute. Many physicists were convinced that this experiment caused problems, and only Einstein thought that it most likely did not exist, because further study of the principle of the constant speed of light, as well as the simultaneity of relativity, time dilation, etc., eventually led to the special theory of relativity, which Einstein was 26 years old in 1905.

Since then, the interference with absolute space-time vision, time is relatively not absolute, the easiest way is to understand what, since the speed of light does not change, space-time cannot be constant, they can expand and contract, that is, the time dilation effect and the scaling effect. In fact, Einstein proposed the concept of four-dimensional space-time, not the four-dimensional space he believed, which is an indivisible whole and relative space.

On top of the three-dimensional space-time is the four-dimensional space-time, the four-dimensional space plus the time axis, in addition to the three-dimensional plus the time axis, there is another latitude in this four-dimensional space-time, and this latitude and the other three latitudes are unified units of measurement, so space and space-time are two concepts.

Time is absolutely silver-changing, why? Because time is a generalized abstract existence, a rational existence. This is just like the fruit we are talking about, it is sensual and simple does not exist, no one has ever eaten an abstract fruit, and it is existential, we can't say that the fruit we generalize from apples, pears and plums does not exist, it exists, it is a universal existence, it is a universal existence, so it is an absolute, eternal existence, it has no life at all, how can it disappear, so it is said to be an eternal existence.

Because in the four-dimensional space, the position and state of the object are different at different points in time, the time axis can be regarded as the imaginary axis, and the three-dimensional space is the real axis, and the problem of the object being imitated by hand will be affected by time.

Because space is affected by the time expansion effect and the shrinkage effect, it is difficult to verify such a space, and it will be affected by the speed of light.

Because in the thinking space, the proportion of time is not particularly large, and it will also be reasonably planned according to the specific situation.

According to people's inferences, it is believed that there are some changes in time in four-dimensional space, such as the difference between three-dimensional space and two-dimensional space.

This is to say that each section is relative to the total time.

Chen's Cosmological Model (Chinese Taiji Cosmological Model): Fallacies will always find all kinds of excuses that are inconsistent with objective reality, otherwise there is room for survival?

It's not the same thing.

First of all, the wrong way to say that "four-dimensional space is defined as three-dimensional space + time axis", and "three-dimensional space + time dimension" is another way of saying it. The former is not a four-dimensional space-time, and the four-dimensional space-time itself is a pseudo-concept. It's very simple: "The concept that time only appears because of the motion of particles and the expansion of the universe, why does it become the fourth dimension?"

In addition, there is a difference between the concept of space-time and four-dimensional space, and the statement that four-dimensional space is defined as three-dimensional space + timeline is a misunderstanding of the concept of Minkowski space, and why is this misunderstanding so widespread? It's very simple, countless science fiction ** and even popular science books deliberately apply such a thing, causing a wide range of readers. This involves a set of four-dimensional vector fields, namely:

Four-dimensional vectors are distinguished by the positive and negative signs of their (Minkowski) inner product. It can be categorized as follows:

It's timelike, it's spacelike, it's null or lightlike, but there's a useful result for zero-vectors: "If two zero-vectors are orthogonal (i.e., zero-in-product), they must be proportional (constant). ”

The above zero-based temporal direction selection, as well as the concept of time-like vectors, make many people mistakenly think that "space and time form another space", when in fact it only describes the synergy of time and space. This is the ** of the previous statement.

So what is the latter statement, that is, the "time dimension"? In fact, the time dimension is an alternative statement, not that the fourth dimension is time, and the previous statement is not the same thing, the fourth dimension has continuity in the mainstream statement, the famous mathematical model Klein bottle, the fourth dimension passes through the essence polyhedron of three dimensions, but the essence of the four-dimensional space is still space. And why this dimension is defined as the time dimension is because there is a certain school of thought that the extended "time" is spatial, so an alternative way of saying it can be called anything, it is a nomenclature based on the autonomous concepts of different schools of thought produced under a unified and definite definition concept.

For four-dimensional space, there is more timeline than three-dimensional space, and most people may only think that there is a timeline on the axis of length, width, and height, but most people still know little about its specific situation.

Now those of us who live in three-dimensional space "interfere" with it. We just need to take the two-dimensional person out of the circle from the third direction (i.e., from the direction of the axis that represents the height) and put it back in the other part of the two-dimensional space.

For those of us in three dimensions, the situation in four-dimensional space is very similar to the above explanation. If we can overcome the four-dimensional space, then it is not impossible to cross the distance of the three-dimensional space in an instant.

Let's do another experiment: weave some rubber ropes into a net according to the pattern of warp and weft, flatten it, we can approximate it as a two-dimensional plane, and then put a small ball on the net, and the rubber net is concave under the gravity of the ball, which forms a three-dimensional space.

However, when looking at this space from the inside, it is often difficult to see clearly, and those two-dimensional flat film people may not realize that the space they live in has been distorted. When they come to the depression from a flat surface, and the depression is deep enough or distorted to a certain extent, the two-dimensional flat-sheet people may also be free to travel to and from the three-dimensional space.

One-dimensional space, two-dimensional space, four-dimensional space, five-dimensional space, ......There is also a timeline, and time is just the concept of the occurrence of particle motion.
