The struggle of ordinary people transcends time and space
The scientific community has not yet reached a consensus on this issue. Stephen Hawking's "A Brief History of Time" discusses this topic in detail, and it is recommended to read the book carefully to learn about relativity and quantum mechanics, which will help with understanding. Hawking believes that even if it were possible to exceed the speed of light, it would not be possible to truly traverse space-time, and time reversal is just an illusion. Superluminal events would trigger a series of quantum mechanical reactions in time and space, ultimately making it impossible to traverse space-time. Of course, some scientists have different opinions on this matter, and there are ways to traverse space-time beyond superluminality. As for the issue of historical trajectory, it has been discussed in detail in "A Brief History of Time", with several different views, but overall, history is mainly random and uncertain, not everything is fixed and accurate.
Even today, people still hold the view that time is a one-dimensional length, and the unit of time should be expressed in "hours" or "seconds". Is this really true? Here I boldly raise a few questions: If time is indeed a one-dimensional length, why can't it be measured with a standard ruler but must be calculated with a standard clock? Since time is a length, why can't it be expressed in units of meters instead of "hours" and "seconds"? Are "hours" and "seconds" also units of length? If they are, what is their relationship to meters? Can the two be converted? On the other hand, if they are not units of length, why use them to express time length? I believe these questions have never been raised before, and are extremely difficult to answer. At least, it can't be said that they are childish questions. Questions that cannot be answered are certainly not childish.
It can be said with certainty that the time concept we use today is ambiguous and contains many obvious contradictions, which should be said to be entirely a contradiction of our own theory, having nothing to do with time itself.
Throughout history, due to people's incorrect understanding of the concept of time, all relevant physical theories today cannot be considered correct scientific theories. Although existing physical theories can also explain local aspects of the universe to a certain extent and seem to be correct, they will never be able to establish a complete and unified cosmic scientific theory. The reason lies in that we do not truly understand "time".
In fact, the universe is extremely simple, so the scientific theories that explain the universe must also be extremely simple, not the opposite. It far exceeds all of our imaginations. The more you imagine the universe to be complex and mysterious, the less you will grasp it; if you imagine the universe to be very simple, you will surprisingly find that the universe is transparent, with nothing but quantity and its distribution, at which point you will be speechless.
The premise of unraveling the mystery of the universe lies in unraveling the mystery of time, and the premise of unraveling the mystery of time lies in breaking through the traditional "time concept", which is both a thin paper window and an iron wall. If you have the imagination to transcend Einstein, this thin paper window will be broken with one poke, do you believe it? Now let's break through the mystery of time.

In the real universe, the image of time is not "one-dimensional length" as we imagine, but should be "three-dimensional volume". The unit of time cannot be expressed in "seconds" or "meters", but should be expressed in "cubic meters". What people usually call "hours" and "seconds" as well as "days" and "years" do not represent units of time, but only represent "angular" units. In the real universe, the true image of time is not an angle, but a "solid angle" that exists in the angle. Now let's discuss this issue specifically, starting with clocks:
We know that the dial area of different clocks is not the same, but the angles existing in all clock dials are completely equal, which are 360 degrees. When the hour hand rotates one week on the dial surface, we say that the hour hand has passed twelve hours of time, and it can also be said that the hour hand has rotated 360 degrees. This shows that the twelve-hour unit on the dial is equivalent to 360 degrees, and the one-hour unit on the dial is equal to 30 degrees. From this point of view, the concept of an hour is not a length unit, but actually represents an angular unit, and hours and angles can be converted from each other. In other words, what we call an hour is actually another name for 30 degrees on the dial; conversely, 30 degrees on the dial are equivalent to one hour.
There must be someone who will ask: if you say that "hour" is not a unit of time but can only serve as an angular unit, then what does the one hour we usually talk about mean? We still use clocks to illustrate.
On the dial, if the hour hand moves thirty degrees, we say that the hour hand has passed one hour of time. This is equivalent to a radius on the dial sweeping an angular area of thirty degrees; If the hour hand moves three hundred and sixty degrees, it is equal to this radius sweeping the circular area of the entire circle. We say: whether it is the angular area of thirty degrees or the circular area of three hundred and sixty degrees is the time embodied in the "clock", in other words: In the "clock", the image of time is intuitively embodied as an area unit, so-called "one hour" is the angular area of thirty degrees on the dial, and "twelve hours" is the circular area of the entire circle.
Now we know that in the "clock", the concept of hours is actually referring to angular units, and what is called time is only embodied in the area of angles. Therefore, we should no longer say: how long is time? But can only ask: how big is time? The unit of time cannot be expressed in seconds, nor should it be expressed in meters, at most it can only be expressed in square meters.
Are you surprised at this point? Please don't rush to refute me. The dial area and scale of all clocks are stationary, representing static time, and the clock hands are moving, representing moving objects, which means that objects can only move in static time. When the clock hand stops moving on a certain clock, we cannot say that the "time" inside the clock has stopped, because the dial and scale representing the time area were originally stationary, we can only say that the moving clock hand has stopped in time. This means that time itself is always stationary, and time is static.
In the "clock", the hour hand is like a moving object, which can only pass through the time area, and time is the area swept by the movement of the object rather than the distance length it has traveled. On all dials, it cannot show the length of the time segment, but only the size of the time area. Some people may disagree with this view, thinking that if the hour hand on the dial is considered to be composed of countless point masses as a radius, then each point mass will sweep an arc line, which can be represented by a unit of length in meters, and time will still be represented as length. We acknowledge that all areas are ultimately composed of stacked line segments, but any line segment, no matter how fine, will have a certain width and can still be considered an area unit from the perspective of essence. Similarly, on the dial, moving point masses, no matter how small, should be viewed as a segment of radius, and the trace it leaves during rotation must be composed of length and width, forming an area. Therefore, we say that the image of time on the dial can only be represented as an area, not a length. A single unit of length cannot uniquely determine the size of an area.
Through the above analysis, it will definitely give people a misconception that time is indeed an area unit. In fact, this understanding is also incorrect. The "time" we mentioned earlier is only the time in the clock, not the real meaning of time. The true meaning of time is neither a length unit nor an area unit, but only a volume unit.
We know that all clocks were originally set according to the Earth's rotation principle, and the Earth is the true standard clock. All clocks should be seen as projections of the Earth clock, and time on this projection plane can only show area characteristics, while in the Earth clock, the true image of time must be embodied as volume.
The Earth's rotation for one week is equivalent to traveling 360 degrees, but the Earth's rotation for one day does not equal twelve hours, it is defined as twenty-four hours. This means that an hour on the Earth clock should be equivalent to a fifteen-degree angle in the sphere. Unlike traditional clocks, the "time" in an hour unit on the Earth clock is not the area of the angle between two radii, but the volume of the angle between two hemispheres perpendicular to the Earth's axis. This is like cutting a watermelon into twenty-four equal pieces, each piece having a shape similar to the volume of an hour unit. If we consider these twenty-four volumes as a whole, it forms a spherical volume that exists in the Earth clock's circular motion, which is the time volume occupied by the Earth's rotation. The size of this time volume can be calculated based on the Earth's radius and the formula for the sphere's volume. The time volume occupied by the Earth's rotation coincides with and equals the spatial volume occupied by the Earth's mass. Here, "time and space" are finally unified in a three-dimensional volume.
In the globe, the image of time is not the arc distance that a particle passes through, nor the area swept by the rotating radius, but the volume swept by the rotating plane. The unit of time cannot be expressed in meters or square meters, but only in cubic meters.
Someone once vividly likened time to a time pipe or time tunnel, which is a genius metaphor. Since it's a tunnel, it must be represented by volume, but any time pipe can't be a straight pipe, it's a closed curved pipe. This is because the movement of all objects is within a certain range of rotation, just like clock hands and the Earth rotating in an angle, whether it's an atom, solar system or the entire universe.
In the solar system, the Earth's orbit is a typical time tube. Of course, this time tube is imagined in our minds, and it is the volume swept by the Earth as it orbits the Sun once. The size of this volume is equal to the product of the Earth's maximum cross-sectional area and the average circumference of the tube. In the solar system, all planets rotate around the center of the Sun in their own time tubes. Since the cross-sectional areas and average circumferences of different planetary tubes are different, we say that each planet occupies a different volume of time, and they do not occupy the same volume of time. All planets orbiting once is called passing through one year or 360 degrees, which means that the unit of a year actually represents 360 degrees in the solar system. The volume of the time tube in an Earth year must be different from that in a Jupiter year. It can be said that the volume of time occupied by Jupiter's rotational motion is obviously larger than that occupied by the Earth's motion, just like the spatial volume occupied by Jupiter's mass is larger than that occupied by the Earth's mass, and they are not in the same spatial volume either.

On the globe, all objects can be seen as rotating around the earth's axis in their own time pipes like hourglasses. The product of the cross-sectional area of the time pipe of any single object or particle and the circumference of the pipe is the time volume occupied by the rotational motion of that object. The cumulative sum of the time pipe volumes of all objects or particles on the globe constitutes the total time volume occupied by the earth's overall self-rotating motion, which is also a typical time pipe with the earth's axis as its center. The earth is a spherical clock and the prototype of ordinary clocks. Each single object on the earth does not move in the same time pipe volume, or it does not have simultaneity, but they are all in a larger time pipe volume at the same time, which is the total time pipe volume of the earth, its size is equal to and coincides with the spatial volume occupied by the earth's mass.
As for the universe as a whole, it is the largest standard clock. In this cosmic clock, there exist clocks of various levels and sizes, including galactic clocks, solar system clocks, Earth clocks, atomic clocks, photon clocks, etc. The movement of all objects in the universe is like an ever-turning dial that determines its position and coordinates in the time volume. What we feel today as the fast or slow passage of time is not actually the fast or slow passage of time itself but rather the fast or slow rotation and revolution of the Earth, which is directly related to the momentum and speed of the Earth. To find out the final answer, we must discuss them in order.
