New 7-Dimensional Theory May Finally Solve the Black Hole Information Paradox.
Researchers propose that extra-dimensional spacetime torsion prevents black holes from fully evaporating, leaving remnants that preserve quantum information.
One of the biggest unsolved problems in modern physics, known as the “black hole information paradox,” may finally have a compelling solution. The proposed answer could also help explain where the mass of fundamental particles comes from.
In the 1970s, Stephen Hawking showed through semi-classical calculations that black holes are not completely black. Instead, they emit a faint form of radiation that slowly drains their energy until they eventually disappear. This creates a serious conflict with quantum mechanics because it appears to destroy information permanently, violating the principle of unitarity. According to quantum physics, information cannot be erased, yet black hole evaporation seems to do exactly that.
In the study published in General Relativity and Gravitation, the researchers examined the effects of a gravity model called Einstein-Cartan theory in a seven-dimensional framework built on a mathematical structure known as a G2-manifold with torsion. Unlike standard general relativity, this theory allows spacetime not only to bend but also to “twist” through a property called spacetime torsion.
The model produces an intriguing result. At the extreme densities associated with the Planck scale, this torsion creates a repulsive force that opposes gravitational collapse and stops the final stage of Hawking evaporation. Instead of disappearing completely, the black hole leaves behind a stable “remnant” with a predicted mass of about 9*10-41 kg.
According to the team, quantum information becomes encoded within the long-lasting “vibrations” of the torsion field inside the remnant. Their calculations indicate that a remnant formed from a black hole with the mass of the Sun could store roughly 1.515*1077 qubits of information, enough to resolve the paradox.
The study also has major implications for particle physics. The researchers found that reducing the geometry from seven dimensions to four dimensions, which corresponds to observable spacetime, naturally produces the electroweak scale (~246 GeV). This scale is closely tied to the Higgs field, which gives elementary particles their mass.
