Mark Jagg In response to your last comment here "The term expansion of space : Q. What fabric is space made of..? The concept of reasoning tells us space has always existed:"
January 18, 2025
"Space" is often used as an abstract term, but in physical terms, it does not apply directly, since space is traditionally defined by the dimensions of height, depth, and breadth within which all things exist and move. In contrast, dimensions refer to specific measurable extents, such as length, width, height, or depth, each representing a quantifiable range or distance through which events unfold.
While dimensions are conceptualized as properties within a coordinate system, they are inherently abstract and mathematical. On the other hand, height, depth, and breadth are specific representations of measurable length, and their combination defines the extended volume we call space—an expanse in which existence occupies and events occur.
Thus, space itself does not have an abstract physical structure but is constituted by the events of existence within it. The structure of space can be viewed as an abstract concept, but it lacks a direct physical application outside the occurrence of events.
From a logical standpoint, space becomes meaningful only when an event with physical existence takes place. Time, too, is intrinsically tied to space and can only manifest in conjunction with it. Therefore, both space and time are rendered meaningless without the occurrence of physical events within existence.
Moreover, it is established that no known physical pre-existence existed before the Big Bang event, implying that the familiar concept of space and time as we understand it did not exist before this moment.
Thus, space and time must have originated from the Big Bang event, emerging as fundamental aspects of our universe post-singularity.
