This theory suggests that reality is not fully fixed in advance but becomes progressively defined through observation and interaction with gravitational potentials: Do decoherence, gravity, dark matter and dark energy all originate from quantum corrections?
* The author proposes that dark matter and dark energy are not physical substances, but rather effective phenomena arising from quantum corrections to gravity.
* Using the Wigner–Moyal equation, the study suggests that higher-order quantum terms act as additional forces depending on the observer's resolution of phase space.
* The research interprets "dark matter" as these quantum-corrected forces appearing in high-curvature environments like galaxies.
* The model accounts for "dark energy" by suggesting that reduced gravitational potential at cosmic distances causes a transition toward classical dynamics, mimicking accelerated expansion.
* This framework aims to explain relativistic effects and galactic rotation curves without invoking new particles or mathematical singularities.

A new paper by SFI Professor David Wolpert introduces a mathematically precise framework for the simulation hypothesis, challenging several long-standing claims and opening up new questions about simulated universes.
Physicists suggest time may not be a fundamental aspect of reality but an emergent property from quantum entanglement. A study published in Physical Review A proposes the Page and Wootters mechanism, where time emerges through the entanglement between a clock and the system it measures, offering a potential resolution to the inconsistency of time in quantum mechanics and general relativity.
A recent study proposes that the universe functions as a vast quantum gravity computer, processing information at the Planck scale at an incredible rate, potentially influencing how physicists view cosmic interactions and energy conservation.
A new model explains the small Higgs mass and the strong-CP problem by invoking a multiverse scenario. It predicts distinctive signals at hadronic EDM, fuzzy dark matter, and axion experiments.
This article presents a white paper summarizing current knowledge on quantum gravity phenomenology and its multi-messenger signals. It provides an overview of the field, discusses experimental and observational signatures, and identifies key questions and challenges.
Astrophysicists have detected subtle hints that the mysterious 'dark energy' that drives the universe's expansion may be slightly weakening over time.
