Title: Nature of Space And Dimension of Observable Universe and Beyond Journal: International Journal of Empirical Research Methods Volume: 2 Year: 2024 Issue: 2 Article Number: 002 URL: https://guinnesspress.org/publication/journal/ijerm/002 ISSN: 2995-6110 Abstract: My innovative research of space, space definition, types of space, and space transformation methods resulted in space transformation law and space-matter transformation law. These space transformation methods and laws govern the nature of the entire space. Finally I have covered the entire existence of space-time (Spacetime, 2022) and beyond by “Dimension of Observable Universe and beyond”. As we know, the universe is defined as all spacetime and its contents (Universe, 2022). However, questions are still open for higher dimensions (String theory vs Loop quantum gravity: Wild hunt for Quantum Gravity:, 2020), the singularity (Gravitational singularity, 2022), gravity collapse at the horizon of the black hole, unified gravity, theory of everything (Theory of everything, 2022), dark matter (Dark matter, 2022) (What is dark matter made of? Leading theories explained: Axion, Wimp, Machos, 2020), dark energy (Dark matter, 2022) (What is dark matter made of? Leading theories explained: Axion, Wimp, Machos, 2020), existence beyond the observable universe and for the space itself. These open questions have driven this scientific research of “Nature of Space and Dimension of Observable Universe and Beyond”. My research findings indicate that the space itself is an entity with physical properties. The space transforms/converts to matter and v/s. The higher dimension is extended beyond the singularity (Gravitational singularity, 2022), beyond the horizon of black holes and beyond the observable universe (Universe, 2022). Several types of research have been done, which include Minkowski Space (Minkowski space, 2022), General relativity (Quantum Gravity: How quantum mechanics ruins Einstein’s general relativity, 2020) (General Relativity Explained simply & visually, 2020), Loop Quantum Gravity (String theory vs Loop quantum gravity: Wild hunt for Quantum Gravity:, 2020), String theory (Standard Model, 2022) (String theory vs Loop quantum gravity: Wild hunt for Quantum Gravity:, 2020) (String theory, 2022) (Theory of everything, 2022), Higgs field (Higgs boson, 2022), Aether medium (Aether (classical element), 2022), the questions are still open for higher dimension, unified gravity, dark matter (Dark matter, 2022) (What is dark matter made of? Leading theories explained: Axion, Wimp, Machos, 2020), dark energy (Dark energy, 2022) (What is Dark Energy made of? Quintessence? cosmological constant?, 2020), theory of everything (Theory of everything, 2022) and space beyond the universe. By researching the existence of matter, I found that the existence of space was just accepted as the void, empty, and space-time background framework. There are well research attempts made to look into space-time as the entity and look for higher dimensions by Loop Quantum Gravity (Loop Quantum Gravity Reveals What Came Before the Big Bang, 2018) and String theory (String theory, 2022). It became very important to define space and to research the relationship between matter and space. It would not be possible without defining higher dimensions. My research reflects the “Dimension of the Observable Universe and beyond” accommodates all existence of the observable universe and beyond the observable universe. The definition of space, type of space, space transformation and space-matter transformation perfectly describe the existence of the entire space & universe and its nature at a very fundamental level. Also, the definitions of the GODEYE and GODEYE Model explain the phenomena of universe expansion-contraction and phenomena of gravity at a very fundamental level for the “dimension of the observable universe and beyond”. It is the most accurate foundation to answer those open questions. It is the novelty in astrophysics and the foundation of entire existence. DOI: 10.59762/ijerm205275792220240705094340
