Quantum mechanics has been extraordinarily successful, yet fundamental problems remain, including the measurement problem, nonlocality, and the absence of a complete theory of quantum gravity. This paper proposes a measurement-centric framework in which spacetime is not fundamental. Instead, reality emerges from measurements occurring within a universal probability space composed of interconnected packets of information. Each measurement updates this structure while preserving its underlying symmetry. This framework offers a natural explanation for nonlocality, clarifies the role of observers, and connects general relativity to the conservation of symmetry.

The quantum measurement problem arises from a structural asymmetry in standard formulations of quantum mechanics: while unitary evolution is treated as fundamental, irreversible events are introduced only through ad hoc postulates. As a result, measurement, decoherence, and probability appear conceptually disconnected. In this work, we propose a minimal reformulation in which irreversible interaction events are taken as ontological primitives. An event is defined as a completely positive, trace-preserving map that is not equivalent to any unitary transformation. Unitary evolution emerges as an effective description valid between events. Within this framework, quantum measurement is not a special process but a particular class of irreversible events with outcome-resolving structure. The Born rule arises naturally from the statistical structure of event realizations, and environmental decoherence is reinterpreted as a high density of irreversible events. No collapse postulate, observer-dependent rule, or modification of quantum dynamics is required. This formulation provides a unified and physically grounded resolution of the measurement problem and establishes a conceptual foundation for event-based extensions connecting quantum theory with spacetime and gravity.
The Schrodinger equation is incomplete, inherently unable to explain the collapse of the wavefunction caused by measurement; a fundamental issue known as the quantum measurement problem. Quantum mechanics is generally constrained by the uncertainty principle and, therefore, cannot interpret definite observations without uncertainty. Here, we resolve this enigma by demonstrating that in phase space quantum mechanics, particularly through the Wigner Moyal equation, uncertainty can be arbitrarily adjusted by tuning the observation window. An observation window much smaller than the uncertainty limit causes substantial nonlocality, rendering the problem ill posed. This suggests that only with sufficient uncertainty does nonlocality become bounded, resulting in a well posed universe. Conversely, in the absence of uncertainty, spacetime is warped beyond recognition, and the system exists as a superposition of numerous possible states. Measurement collapses this superposition into a unique solution, exhibiting timeless nonlocal interactions. Our framework bridges seemingly disparate concepts such as classical mechanics, quantum mechanics, decoherence, and measurement within intrinsic quantum mechanics even without invoking new theory.
Quantum measurement is a fundamental concept in the field of quantum mechanics. The action of quantum measurement, leading the superposition state of the measured quantum system into a definite output state, not only reconciles contradictions between quantum and classical mechanics but also facilitates quantum state manipulations, including reading and resetting. Despite its significance, four fundamental issues -- randomness, instantaneousness, irreversibility, and preferred-basis -- continue to pose significant challenges to the broader application of quantum measurement and our overall understanding of quantum mechanics. In this work, we employ a new space-time approach to relativistic quantum mechanics to address these issues systematically. Our approach provides a comprehensive elucidation of the intricate connections between quantum measurement and quantum unitary evolution, as well as an in-depth analysis for the interdependence of non-local correlations and relativistic theories. We thereby reveal a more fundamental dynamical theory, beyond the traditional time-evolution equation in quantum mechanics, where the axioms of quantum measurement naturally emerge as a corollary. These findings contribute to the advancement of related fields, and our work holds potential implications for future research and applications in the realm of quantum mechanics.
Abstract The ontological status of time remains unresolved in fundamental physics. In quantum mechanics, time appears as an external classical parameter, whereas in general relativity it is dynamical and intertwined with spacetime geometry. Canonical approaches to quantum gravity, most notably the Wheeler–DeWitt formulation, eliminate time altogether, leading to the well-known “problem of time.” These tensions motivate frameworks in which time is not fundamental but emergent. In this work, we propose a discrete, update-based framework in which the universe evolves through a sequence of global quantum states indexed by an abstract update parameter rather than by a physical time coordinate. Evolution is formulated as a completely positive, trace-preserving (CPTP) quantum channel acting on the universal density operator, ensuring exact conservation of probability and global quantum information at every update. The framework is deliberately conservative: it preserves the formal structure of quantum mechanics and quantum field theory, enforces vacuum stability, and supports global conservation laws without introducing new dynamical postulates. Within this setting, time emerges relationally at the level of subsystems. As subsystems become increasingly entangled with their environments, entropy gradients arise that define an effective arrow of time, closely aligned with the thermodynamic arrow. The resulting temporal flow is relative, statistical, and observer-dependent, while the global evolution remains information-preserving and, in the closed-system limit, reversible. We explore the implications of this framework for cosmology and black hole physics. The Big Bang is reinterpreted as an initial quantum state rather than a singular beginning of time, avoiding temporal singularities. Black hole evaporation is shown to be compatible with unitary evolution when the full quantum state is considered, naturally reproducing the expected Page curve and resolving the apparent information paradox. Overall, the framework provides a coherent, minimal setting in which time, irreversibility, and cosmological history emerge from quantum correlations rather than from a fundamental temporal background.
By offering mathematical frameworks and experimental techniques for characterising matter, energy, space, time, and their interactions, physics plays a crucial role in comprehending the nature of reality. The evolution of contemporary physics, from classical mechanics and electromagnetism to quantum mechanics and relativity, has profoundly altered our comprehension of the cosmos and put traditional ideas of determinism, locality, causation, and observation to the test. The contribution of modern physics theories to our comprehension of reality at the microscopic and cosmological sizes is examined in this paper. The measurement problem, entanglement, quantum information, quantum physics, and the connection between physical information and the emergence of observable reality are all given special emphasis. The study also looks at how understanding space, time, matter, and the structure of the cosmos is affected by general relativity, quantum field theory, and new theories of quantum gravity. Additionally, the potential connection between information, awareness, and physical processes is rigorously examined, separating accepted scientific findings from theoretical and philosophical interpretations. The study shows that relationships, information, and physical rules may be a more fundamental way to define reality than traditional ideas of independently existent objects by combining findings from theoretical physics, quantum information science, and philosophy of physics. The study concludes that while unanswered problems about quantum measurement, the origin of spacetime, and consciousness point to significant avenues for future multidisciplinary research, physics is still a potent framework for examining fundamental reality.
