What is time – this is a question that has been on the minds of many philosophers since ancient times. Since modern people are immersed in a socialized consciousness for most of their lives, they tend to think of the concept of time as time, which is measured mainly by clocks. This image of “clock time” refers to the sense that there is another dimension called time, separate from the three dimensions of space, in the objective external world and that it flows linearly from the past to the future. From this linear concept of time similar to space, time seems to exist in the external space independent of “I” and space. This concept of time is very similar to Newton’s idea of absolute space and absolute time.
However, an event in physics at the beginning of the 20th century overturned this concept of time. It was the advent of Einstein’s theory of relativity (special). According to the theory, space and time can no longer be considered separate modes of entities but rather as a four-dimensional continuum called “space-time,” in which time and space are a coherent whole. It is often said that our space has four dimensions, consisting of three dimensions of space and one dimension of time. However, to be precise, it is a 4-dimensional space-time, and there is no independent dimension of time that exists separately from space. The characteristic of this concept of “space-time” is that time always exists as a set within space. If there is a spatial gap, there is also a temporal gap simultaneously. Therefore, the space we inhabit cannot exist without time.
The absolute measure in this 4-dimensional space-time continuum is the speed of light. The speed of light is generally considered about 300,000 km/second, but as I wrote in 2013: Sirius Revolution, it is not something that fits in the concept of “speed.” Einstein himself clearly stated in his first thesis, “On the Electrodynamics of Objects in Motion (1905),” in which he wrote about special relativity, that “the speed of light will play the role of infinite speed in our physics in the future.” In other words, in the physics system, 300,000 km/s means infinite speed. But what exactly do we mean by infinite velocity? To put it simply, it means that the speed of light is not the same as what we generally regard as velocity.
Due to the infinite nature of this light speed, any distance is supposed to be traveled instantly once the traveler reaches the light-speed state. So, for example, if a rocket capable of traveling at light speed could travel to the Andromeda Galaxy, which is said to be 2.5 million light-years away, its crew would reach the Andromeda Galaxy in an instant. That is because, as you know, time stops at the speed of light. But for the families of the crew left on Earth, by the time the rocket reaches the Andromeda Galaxy, 2.5 million years will have elapsed. Hmmm. Really? Well, it’s a story that always appears in the general relativity manuals, but it sounds very strange, doesn’t it? But the consequences of the relativity theory allow for such absurd events.
If we consider the expansion of space through this time-space concept, the world on the sphere that appears 2.5 million light-years away from the earth is, in fact, 2.5 million years old. The perception of the expansion of macro-space requires objects/matters, be it a star or a nebula. The information about the existence of that object/matter is conveyed by light. Thus, the star we see on the earth “now” is light emitted from a star 2.5 million years ago and arrived at the present. Here, the concept of observing space through light is applied to our way of thinking. And we can see that such a premise for our idea about time and space implicitly depicts a picture of light traveling through space like an object in our mind. It is the image of a ray of light rushing through space at the speed of light.
Suppose you placed a flashlight on the left and a white screen on the right. When you turn the flashlight on, photons are ejected from the bulb’s filament and irradiated onto the screen, which is several meters away. Then, with a precise measuring instrument incorporating an atomic clock, you measured the time interval between the “on” of this switch and the arrival of the photons on the screen, and it was 0,000……1 second. And so on.
Now, something is strange with this idea. Here, the idea of “width” is dominantly reflected. In the system on the measured side, which is a purely physical world, it may be sure that light travels at 300,000 km/second between the width of “there” to “there.” But what is of interest here is the atemporal world of light itself, which is rushing along at the speed of light. What does this mean? Physics explains this timeless world in terms of a four-dimensional invariant distance expressed by the following equation:
ds^2 = dx^2 + dy^2 + dz^2 – c^2dt^2 ds^2 = 0
The equation shows that for light itself, any distance is meaningless. The theory of relativity was initially derived from only two principles: the principle of relativity of motion and the principle of light-speed invariance. In this context, this light-speed invariance serves as immovable, an absolute system that compares the relative motions of the two systems. However, many physicists do not seem to delve into the significance of the light-speed invariance as this “immovable system” even though spacetime exists based on the assumption of light-speed invariance. Why is that? In Noosology, the relationship between light speed and spacetime contains a vital meaning (the boundary where the shift of our “NAIMEN (the Inside=invisible) of human being” to “GAIMEN (the Outside=visible) of human being” occurs), as I wrote in 2013: Sirius Revolution. Since this is a very important point, I will mention it here again.
The current popular depiction of light moving through space-time at the speed of light is a fallacy. Instead, we should consider that there first existed the speed of light. All extended notions of time and space are derivatives of it (in the language of Noosology, existence is essentially preceded by “the Outside(visible) “of human being).
Here, too, you can see that the issue of objective and subjective lines, which I wrote about in 2013: The Day God Sees God, is treated ambiguously. Newtonian physics was the physics of an uninhabited world in which the existence of an observer was never an issue. The world exists with absolute space and absolute time in its background, without any relation to “I,” the observer of the world. And the universe exists as a three-dimensional expanse of space with time ticking by every second, regardless of whether the observer exists or not. So –it was physics that dealt with the motion of objects unfolding in such a simple place. Philosophically speaking, this is the world of naive realism. However, with the advent of Einstein, the nuances of space and time have changed a little (I say “a little” because the conceptual framework for space-time has not gone beyond the realm of naive realism, although within physics, it may be called a radical change). The reason is that although we call it “physics,” a “conscious being” called the “observer” had been mixed in there. From this arises one simple, intuitive deduction: The existence of an “observer” may be the key to the concept of 4-dimensional space-time. –The observation of some event. A description of when and where the event occurred. Without witnesses, no event can be uncovered. Without observers, space-time cannot exist. Then, in what way are the “observers,” the witnesses of space-time, involved in the events? And the most critical issue here is that this observing and measuring is also an event, which is necessarily done by light. –To be continued
