Objectives: This review advocates absolute determinism in our universe and reinterprets Quantum mechanics while doing so. Then it discusses some of its consequences across fields. Method: This study starts by proposing the absolute postulate of the universe and derives absolute determinism using concepts from both the classical and quantum mechanics. Then it advocates that though the universe is deterministic, it is unpredictable. Statistical outcomes of a classical experiment and probabilistic outcomes of a quantum experiment are not due to the indeterministic nature of the experiment but due to theoretical limit of calculation/ practical limit of measurement. The study then proposes that the "free will is an illusion". As the paths of the particles are determined, the paths and interactions of neurons and neurotransmitters are determined and thus the thoughts and actions are determined. Thus, free will is an illusion. Then it focuses on some consequences like the outcome of a radioactivity experiment, resolution of Schrodinger’s Cat Paradox and that of EPR Paradox. The study also touches upon chaos theory, Big Bang theory and consciousness. Findings: Based on Bohmian Mechanics, Superdeterminism and Cellular Automata Interpretation, this study proposes a new interpretation of quantum mechanics. Using absolute determinism, it also argues that free will is an illusion and support it with Benjamin Libet’s experimental findings in neuroscience and fMRI scans done later. The study discusses deterministic but unpredictable identification of the particle that will disintegrate next among N particles collected in a block. It also attempts resolution of Schrodinger’s Cat Paradox and that of EPR Paradox. Towards the end, the study explores chaos theory, Big Bang theory and consciousness. Novelty: In the new deterministic interpretation of QM, a distinction is made between what is real in the universe and what is measurable or calculable. For example, it reiterates that a particle’s position and momentum are fixed even if they can’t be measured or calculated precisely and simultaneously (a re-interpretation of HUP). In other words, the study implies that the famous quote of Albert Einstein – “God Does Not Play Dice With The Universe” holds true in the realm of quantum mechanics also as it already does in classical mechanics.
