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.

Recent computer simulations by astronomers at the University of Groningen reveal that the Milky Way and Andromeda galaxies are embedded within a large, flat sheet of dark matter, surrounded by vast voids. This unique mass distribution explains the observed motions of nearby galaxies – most are moving away from us, consistent with the Hubble-Lemaître law, while Andromeda moves towards us. The simulations, built upon observations of the early universe and validated against the characteristics of the Local Group, provide the first assessment of dark matter distribution around our galactic neighborhood and offer a solution to a decades-old puzzle in cosmology. This “flat” arrangement counteracts the gravitational pull of the Local Group for galaxies within the sheet and explains the absence of galaxies in the surrounding voids.

Analysis of 15 years of Fermi LAT data reveals a statistically significant halo-like excess in gamma rays around 20 GeV, potentially originating from dark matter annihilation. The study examines systematic uncertainties and explores implications for WIMP parameters.
The first test images from the Vera C. Rubin Observatory have captured light from millions of distant stars and galaxies, and are expected to reveal thousands of previously unseen asteroids. The observatory is expected to revolutionize our understanding of the universe.
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.
Dark matter detectors designed to spot hypothetical dark matter particles have instead detected a signal from neutrinos produced by the sun. This 'neutrino fog' is both a milestone and a sign that these detectors may soon be overwhelmed by neutrinos, hindering their ability to detect dark matter.
