The information is stored there, preserved, not destroyed.
For fifty years, a question has lingered at the edge of physics: when a black hole vanishes, does the information it swallowed vanish with it? A new theoretical proposal by Richard Pinčák and collaborators suggests the answer is no — that spacetime itself, understood in seven dimensions with a twisting geometry, generates a repulsive force that halts evaporation and leaves behind a stable remnant encoding everything that fell in. If the mathematics holds, the resolution to one of physics' deepest paradoxes may not require rewriting quantum mechanics, but simply seeing the universe's geometry more completely.
- A fifty-year-old contradiction at the heart of physics — Hawking's prediction that black holes evaporate versus quantum mechanics' insistence that information cannot be destroyed — has resisted every attempted resolution.
- The new framework introduces spacetime torsion, a twisting of geometry at Planck-scale densities that acts as a brake on evaporation, leaving behind a stable remnant rather than allowing the black hole to vanish entirely.
- These remnants, predicted to weigh roughly 9×10⁻⁴¹ kilograms, would store quantum information as long-lived vibrational modes — enough to preserve every qubit of what a solar-mass black hole consumed.
- Remarkably, the same seven-dimensional geometry that saves the information also reproduces the electroweak energy scale, offering a potential geometric explanation for why elementary particles have mass at all.
- Direct experimental confirmation lies far beyond current accelerator technology, but the theory makes testable predictions through dark matter searches, gravitational wave astronomy, and analysis of the Cosmic Microwave Background.
In the 1970s, Stephen Hawking showed that black holes slowly leak energy — a process that, followed to its conclusion, means they evaporate entirely. The problem is that quantum mechanics forbids the destruction of information. If a black hole disappears, what becomes of everything it absorbed? This contradiction, the black hole information paradox, has unsettled theoretical physics for half a century.
A new paper published in General Relativity and Gravitation by Richard Pinčák and collaborators proposes a geometric solution. Working within Einstein-Cartan theory — a framework that allows spacetime not only to curve but to twist — the researchers modeled black holes in seven dimensions using a mathematical structure called a G2-manifold with torsion. At the extreme densities of the Planck scale, this torsion generates a repulsive force that halts evaporation before completion, leaving behind a stable remnant with a mass of approximately 9×10⁻⁴¹ kilograms.
That remnant would not be empty. The team proposes that quantum information becomes encoded within it through quasi-normal modes — persistent vibrations of the torsion field — with a solar-mass black hole's remnant capable of storing roughly 1.515×10⁷⁷ qubits, precisely enough to preserve everything that fell in. The paradox, under this model, dissolves without any revision to quantum mechanics.
The proposal carries an additional surprise. When the seven-dimensional geometry is reduced to the four dimensions we experience, the mathematics naturally produces the electroweak energy scale of 246 GeV — the scale at which the Higgs field operates and particles acquire mass. The same mechanism that prevents information loss may also explain why matter has mass at all, touching the long-standing mass hierarchy problem.
Direct testing remains out of reach; the energy scales involved exceed the Large Hadron Collider's capacity by roughly ten million times. But the authors argue the theory is not untestable. The stable remnants could contribute to dark matter, leaving gravitational signatures detectable through astronomy. Distinctive vibrational patterns within the remnants differ mathematically from competing theories, and traces of the seven-dimensional geometry may be preserved in the Cosmic Microwave Background or in primordial gravitational waves. Whether the universe confirms this deeper geometry remains an open question — but for the first time in decades, a single framework attempts to answer several of physics' hardest questions at once.
In the 1970s, Stephen Hawking made a discovery that created one of physics' deepest puzzles. Using the mathematics of quantum mechanics applied to the curved spacetime around black holes, he showed that these objects are not truly black at all. They leak radiation—a faint, steady stream of energy that causes them to shrink over time. Follow that logic to its end, and a black hole eventually evaporates completely, vanishing from the universe. The problem is that quantum mechanics forbids the destruction of information. Whatever fell into that black hole—matter, energy, the quantum states that encode its properties—should not simply cease to exist. Yet if the black hole disappears, where does that information go? This contradiction, known as the black hole information paradox, has haunted theoretical physics for fifty years.
A new proposal, published in General Relativity and Gravitation by Richard Pinčák and collaborators, suggests a way out. The answer, they argue, lies not in revising quantum mechanics but in understanding the true geometry of spacetime itself. The researchers investigated a framework called Einstein-Cartan theory, formulated in seven dimensions using a mathematical structure known as a G2-manifold with torsion. Unlike Einstein's General Relativity, which allows spacetime to bend and curve, Einstein-Cartan theory permits spacetime to twist as well. This twisting—called torsion—becomes crucial at the extreme densities found at the Planck scale, the smallest meaningful length in physics.
At those scales, the team found, torsion generates a repulsive force that pushes back against gravitational collapse. This repulsive effect acts like a brake on Hawking evaporation. Rather than shrinking to nothing, a black hole would halt its decay at the final moment and leave behind a stable remnant—a tiny object with a predicted mass of about 9×10⁻⁴¹ kilograms. That is incomprehensibly small, far smaller than any particle we can observe. Yet it would not be empty. The researchers propose that quantum information becomes encoded within the remnant through what they call quasi-normal modes—essentially, long-lived vibrations of the torsion field that persist within the remnant's geometry. Their calculations suggest that a remnant left by a solar-mass black hole could store approximately 1.515×10⁷⁷ qubits of information, precisely the amount needed to preserve everything that fell in. The information paradox, under this model, dissolves.
But the proposal reaches further still. The researchers noticed something remarkable: when they reduce their seven-dimensional geometry down to the four dimensions we actually experience, the mathematics naturally produces the electroweak scale—an energy of about 246 GeV. This is the energy scale at which the Higgs field operates, the quantum field responsible for giving elementary particles their mass. In other words, the same geometric mechanism that prevents black holes from completely evaporating could also explain why particles have mass at all. This connection addresses what physicists call the mass hierarchy problem, a long-standing mystery about why the forces and particles of nature have the particular strengths and masses they do.
The obvious question is whether any of this can be tested. The particles associated with the extra dimensions—called Kaluza-Klein excitations—would require energies of roughly 8.6×10¹⁵ GeV to create directly. The Large Hadron Collider, the most powerful particle accelerator on Earth, can only reach energies about ten million times lower. Direct detection is therefore impossible with current technology. Yet the authors argue that the theory is not untestable. Because it rests on specific geometric relationships, it makes concrete predictions that could be investigated through astronomy. The stable black hole remnants themselves, if they exist, would be extraordinarily massive for their size and could contribute to dark matter—the invisible substance that makes up most of the universe's matter. Detecting the gravitational signature of these "Planckian relics" would provide direct evidence for the framework. The model also makes distinctive predictions about how information vibrates within the remnants, a mathematical signature that differs from competing theories. Additionally, the extreme energy scales involved are characteristic of the early universe, meaning traces of the seven-dimensional geometry might be preserved in the Cosmic Microwave Background—the ancient light left over from the Big Bang—or in primordial gravitational waves from that era.
What makes this proposal ambitious is its scope. It attempts to solve multiple outstanding problems in physics—the information paradox, the nature of extra dimensions, the origin of particle mass—within a single geometric framework. If correct, it would mean that quantum mechanics does not need to be revised after all. Instead, the resolution would come from recognizing that spacetime has a deeper, seven-dimensional structure, and that the universe's most fundamental laws are written in that higher geometry. The next years will determine whether the universe actually works this way, or whether the black hole information paradox remains unsolved.

The Hearth Conversation Another angle on the story
So if black holes don't actually disappear, where are all these remnants? Why haven't we found one?
They're predicted to be extraordinarily small—about 9×10⁻⁴¹ kilograms. That's far below anything we could detect directly. But they might be everywhere, contributing to dark matter. We'd see them through their gravitational effects, not by looking at them.
This seven-dimensional geometry—is that something physicists have been working toward, or is this entirely new?
Einstein-Cartan theory itself has been around for decades. What's new here is applying it in seven dimensions and showing it solves both the black hole problem and the particle mass problem simultaneously. That connection is what makes it interesting.
You mentioned the Higgs field. How does twisting spacetime explain why particles have mass?
When you reduce the seven-dimensional geometry to our four-dimensional spacetime, the mathematics naturally produces the energy scale where the Higgs field operates. It's not that torsion directly gives mass—it's that the geometry itself encodes the scale at which mass-giving interactions happen.
Can we actually test this, or is it just mathematics?
The theory makes predictions. If these remnants exist, they'd show up in dark matter observations. And if the early universe had traces of seven-dimensional geometry, we might see signatures in the cosmic microwave background or in gravitational waves. It's testable, just not with particle accelerators.
What happens to the information inside the remnant? Is it lost forever?
No—that's the whole point. The information is encoded in vibrations of the torsion field inside the remnant. It's stored there, preserved, not destroyed. The universe keeps its books balanced.
If this is right, does it change how we think about black holes?
Fundamentally, yes. They're not the ultimate destroyers we thought. They're more like sealed vaults—they hold everything that falls in, just in a form we can't easily access.
