"A Brief Treatise on Time and Space" is one of Jiang Wendao's several articles on the insights of time and space.

As the title of the chapter says, it is a superficial discussion of time and space. Summary: Space-time, i.e., time and space. The two are "intimately linked". Time is what exists in nature but cannot be seen. It can be found in every space of nature. And the so-called space is "everywhere". Example: To put it mildly, a bottle is placed on the table, and it is because there is space there, so the bottle can be placed there. To put it more broadly, the earth of heaven and earth, which is often referred to as the planet we live in, exists precisely because there is space there. And the heaven of heaven and earth is actually space, or "extension of space". Solid, heaven and earth = time and space = universe.

And time is the flow rate, and the flow rate here should be described in this way, for example: two people who can live normally to 90 years old, and then die of natural aging. If one of them is placed in a space where the flow of time is twice as fast, then he would have lived to be 90 years old and become 45 years old, and his body, which was originally fully developed at the age of 20, was completed ahead of schedule at the age of 10, which is time, that is, the flow rate. That is, the speed at which it passes.

And time is everywhere in every space, and it is because of the existence of space that time can exist. So it can also be said that (time and space are one).

And in the natural time, I call it (equilibrium flow velocity), that is, the equilibrium and steady flow velocity, that is, in general, the flow rate of time is the same. The reason for this is that not every space has the same flow rate, for example, under some unknown circumstances, a certain space in nature will appear (space-time entrance), which is another name for (space-time tunnel).

Through the research of related paranormal events that occurred in previous history, I have come to the following opinions: First, the so-called (entrance to different time and space) does not mean that you can enter (space-time tunnel) by appearing in a similar hole, but when you appear in a certain space (space-time entrance), you are already in (space-time tunnel) without realizing it. Second, the flow speed of the time tunnel is not the same as the flow speed of nature, which explains why many years ago, when some people "strayed" into the time and space tunnel, many years later, when they came out of it, they were still as young as they were back then. As for why they can't remember what happened, my understanding of this is that the speed of the space-time tunnel (different space-time) is very slow, so slow that they can't feel the passage of time, for example: one second, two seconds, we can all feel its past, but what about a thousandth of a second? What about a ten-thousandth of a second? What about billionths of a second? Of course, perhaps the flow speed of the space-time tunnel (different time and space) is very slow, but it is not as different from the real time, but people's perception, memory does not work "inside", I don't know what happened, I don't know how much time has passed, and there is no memory, which can also explain why they return to reality after many years, and the memory is still stuck in that time, and it is always difficult to believe that they have come from the past to the future. Third, some people may say that the time of the space-time tunnel (different time and space) can't be static, so that when people who strayed into the "inside" came out of it, they had no memory and didn't know how long it had passed, isn't it also normal.

My view on this is that time does not stand still.

The so-called present, past, and future are just a conceptualization, because time is passing all the time, all in the "past". And this also raises the possibility of theoretically exceeding the speed of light.

Concluding remarks of "A Brief Treatise on Time and Space": I can imagine that in hundreds or thousands of years, it may take even longer. When people can control the accurate use of time-space (time tunnel) technology, the future is completely hopeless for 10, 20, or even beyond. As for going back to the past, I think we shouldn't think about it at all, because the real time is always in the past, so no matter how many years from now, if we humans still exist, no matter how much technology at that time has surpassed the present, at most, it can only be infinitely close to the "point of the past", and this is actually the future. The final sentence is: the past cannot be returned, and the future can still be gone. And this also raises the possibility of theoretically exceeding the speed of light.

In the end, Jiang Wendao also left this paragraph in this article: Of course, if you want to go to the future, you must have a high degree of accuracy in the space-time coordinates, otherwise, maybe you can go directly to the bottom of the sea for 20,000 miles in a certain sea area in the future.
