V Herrebrugh https://orcid.org/0000-0002-4088-6657 This paper introduces a conceptual 4-dimensional space time model that departs fundamentally from Einstein’s relativity. Unlike observer dependent systems, this framework emphasizes true simultaneity, distinguishing objective reality from perceived events. It defines a 4D orthogonal vector coordinate system, combining 3D Cartesian space with a fourth dimension of virtual time surfaces, which represent instantaneous temporal slices across space. These time surfaces are curved within an otherwise flat 3D space, forming a dynamic, evolving “present” enclosed at the boundary of the space time system. Time is modeled as an independent scalar magnitude, making it fully orthogonal to spatial dimensions and immune to external influences like gravity. This redefines the role of time as a pure sequence of events, without the curvature or distortion proposed in general relativity. By projecting 3D space onto this new virtual topology, the model offers a unique geometric view of space time. It challenges conventional gravitational space time interactions and repositions time as an unlinked, autonomous coordinate within a unified but orthogonal framework. 03 2025 11 18 10.55672/hij2025pp11-18 https://www.hscience.org/index.php/hij/article/view/151
