Space and Time - the nature of relationship in their relation.

There is only abstract mathematical relationship between space and time, abstract relationship does not depend on reality, so time is independent from reality, existential events are real and also variable, and so there is the requirement of abstract, mathematical time.
However, time does not have interactable relationship with real events (so that events cannot interact with time) but events only invoke time, as time succeeds uniformly and irreversibly - according to its scale.
At the time of Einstein, Universe was not adequately known as it is known today, and so Einstein had to assume the universe as in a steady state, correspondingly infinite succession of time, but now we know that the universe is expanding and time has a beginning these makes Einstein's assumption about time and space was inadequate (This does not mean Einstein's discoveries were less important). Indeed Einstein's discoveries were remarkable but at the same time Einstein wrongfully interpreted character of time and space (those, now we now better).
Definition of time clearly transpires that real existential events invoke conceptual time, while time and space are dissimilar in characters, but there needs to be a mathematical relationship between events and time but not as in interactable relationship but abstract relationship (mathematical).
