Space, object and time must be one complete system, for the existence of objects infers the existence of both space and time. Space, objects and time are not independent of each other.
It is possible to think (imagine) that they are separate “things”, just as we can think of the front and back of a piece of paper as discrete sides, but they are never separate from each other as such (even though with great skill, ingenuity and difficulty we can do it but they will always remain from the original one piece of paper).
