Hidden Fifth Dimension May Tie Dark Matter to Dark Photons in a Resonant Link

A new theory posits that dark matter and dark photons share access to a hidden fifth spatial dimension, where the dimension's geometry enforces a fixed mass ratio via a dark matter resonance. This resonance would have amplified interactions in the early universe and weakened them as the cosmos cooled, potentially explaining why direct detection remains elusive today. The idea is being tested by experiments such as CERN's NA64, with complementary searches like HeRALD and Oscura; the framework could also address small-scale structure issues like the scarcity of dwarf galaxies. While MOND remains an alternative, Gaia and Fermi data currently favor dark matter models.

Dark matter could resonate with a hidden fifth dimension, new theory suggests

A new study proposes dark matter’s ghostly behavior could arise from resonance with a hidden fifth dimension, potentially mediated by a dark photon; the geometry of this extra dimension might drive strong interactions in the early universe while leaving dark matter inert and hard to detect today, offering new directions for dark matter searches.

7D torsion theory suggests black holes leave information-bearing remnants

A seven-dimensional Einstein-Cartan model with spacetime torsion proposes a repulsive effect at Planck scales that stops black hole evaporation, leaving stable remnants that encode information in long-lived torsion vibrations; a solar-mass remnant could store about 1.5×10^77 qubits, potentially resolving the information paradox and linking to the electroweak Higgs scale via dimensional reduction, with testable predictions including dark-matter remnants and distinctive quasi-normal-mode signals—though detecting the extra dimensions via KK states would require energies far beyond current accelerators.

Seven-Dimensional Geometry Suggests Black Holes Leave Quantum Memory

A seven-dimensional Einstein-Cartan theory on a G2-manifold with torsion implies that Planck-scale torsion produces a repulsive effect that halts Hawking evaporation, leaving stable black-hole remnants whose internal torsion vibrations store quantum information. This could resolve the black hole information paradox, while naturally linking the electroweak scale and Higgs field to the geometry and offering potential dark matter candidates and testable ultra-high-energy predictions.

Seven hidden dimensions could trap black holes in tiny remnants, reshaping Hawking’s paradox

A new theoretical study proposes that if the universe has seven space-time dimensions with three hidden compact dimensions (folded in a G2 geometry), a torsion field could halt Hawking evaporation at the end of a black hole’s life, leaving stable microscopic remnants that store information and may connect gravity to the Higgs mechanism—though testing this idea would require physics beyond current capabilities and must contend with the limits of semiclassical descriptions near the Planck scale.

Seven hidden dimensions could stop black holes from evaporating, new physics suggests

A new theoretical study proposes that if the universe has seven dimensions arranged in a G2-manifold geometry, a torsion-induced repulsive force could halt Hawking evaporation at a tiny stable remnant, allowing the black hole to store the information and potentially resolve the information paradox. The model links the existence of extra hidden dimensions to a mechanism that mirrors the Higgs field and predicts concrete, testable implications such as ultra-heavy Kaluza-Klein particles, while acknowledging that a full quantum gravity theory is needed and direct experimental tests are far beyond current capabilities.

Is the Higgs boson essential for mass creation?

A new study proposes that particle mass and fundamental forces could originate from the geometry of hidden extra dimensions, specifically through evolving seven-dimensional shapes called G₂-manifolds, potentially eliminating the need for the Higgs boson in explaining mass.

"Physicists' Quest: Uncovering Missing Matter in the Dark Dimension"

Physicists are exploring the concept of a "dark dimension" within the framework of string theory to explain the minuscule value of the cosmological constant and the potential emergence of lightweight, weakly interacting particles. This theory posits the existence of dark gravitons, which could serve as candidates for dark matter and have implications for the distribution of galaxies. While the idea is intriguing, some physicists remain skeptical, but upcoming experiments, including cosmological surveys and laboratory tests, may provide evidence to support or refute the dark dimension hypothesis and shed light on the nature of dark matter and the forces of gravity.
