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.
