A conceptual 4-dimensional vector space-time in a framework of an orthogonal vector-time coordinate within a 3-dimensional space is introduced for true space time system dynamics.Based upon true time simultaneity of events i.e. absolutivity, this 4D space-time concept departs fundamentally from the observer oriented theory of special and general relativity in separating true, objective reality oriented simultaneous events from observed events and by providing rigorous independency of the four space-time coordinates.The geometric model is conventional Cartesian in 3D space and introduces virtual time-surfaces of true time simultaneity as a fourth dimension for validity in vector- and tensor- spaces, leading to a compliant 4-dimensional orthogonal vector coordinate system of space-time, thereby implicitly introducing a novel space-time topology with independent dimensions.The evolvement of events in this space-time then are traced in a coordinate system of 4 truly independent vector-coordinates in a 4D Hilbert (complex) vector space i.e. with an independent scalar magnitude of the time-vector.The treatment modifies space-time into 4D with curved virtual time-surfaces inside the empty, un-curved 3D continuum, i.e. confining 3D space in a virtual reality of projected, dynamic evolving ‘present’ surfaces, spherically closed as the space-time ‘edge’ of time, receding continually into the ‘past’, thereby building a (dynamic) history of true time information of events across the universe in data-shells.
