Key Takeaways
- Scientists propose black holes might have “hair” that retains information as they evaporate.
- This new theory offers a potential solution to Stephen Hawking’s black hole information paradox.
- The concept suggests gravitational “hair” could act as a bridge, preserving quantum information.

At the core of black hole research lies a paradox that has puzzled scientists for decades. As black holes evaporate over time, they seem to take information with them—information that, according to quantum theory, should be preserved. This conundrum, known as the black hole information paradox, has been a topic of intense debate since Stephen Hawking’s groundbreaking work on black holes. Now, a new theory proposed by physicists from the UK, the US, and Italy offers a fresh approach to this mystery, suggesting that black holes may have “hair” that helps retain information.
The Information Paradox and Hawking Radiation
Black holes are known for their immense gravitational pull, warping space and time to such an extent that not even light can escape their grasp. Decades ago, Stephen Hawking proposed that black holes emit a form of heat radiation, now known as Hawking radiation. Over time, this radiation causes black holes to shrink and eventually disappear. However, this creates a problem: in quantum physics, information cannot simply vanish. Yet, Hawking’s theory implied that the information contained within a black hole would be lost forever as it evaporates, violating a fundamental principle of quantum mechanics.
Physicists have been grappling with this paradox ever since, trying to find a way to reconcile the laws of quantum mechanics with general relativity, which governs how space and time behave around massive objects like black holes.
A Hairy Solution?
The new theory, which has garnered significant media attention, suggests that black holes may not be as smooth and simple as once thought. Instead, they could have “hair,” or slight perturbations in their gravitational fields, that store information. This concept, though not entirely new, offers a potential solution to the information paradox. The idea is that these “hairs” could serve as a bridge between the information inside the black hole and the surrounding universe, allowing the information to remain accessible even as the black hole evaporates.
This theory builds on the idea of gravitons—hypothetical particles that could mediate the force of gravity at a quantum level. Though gravitons have never been observed, the researchers have developed a model based on how these particles might behave under specific conditions. According to their model, the gravitational “hair” around a black hole could retain some of the information, preventing it from being lost completely.
Far from a Final Answer
While this new approach is intriguing and offers a solid theoretical framework, it is far from a definitive solution to the black hole information paradox. Much more research is needed to test and refine the theory, and it may be some time before we can confirm whether black holes truly have “hair” or if this idea leads us closer to resolving the paradox.
In science, progress often comes in two forms: observation or hypothesis. The theory of black holes having hair is a valuable hypothesis, providing a new direction for future research. Whether or not it will ultimately solve one of physics’ most perplexing problems remains to be seen.
This research was published in Physical Review Letters.
With ribbons of light and matter flowing around us, this interesting theory building I’d say it sounds like black holes are a bacterial colony or fruiting fungi with the hair being the mycelium?! Why should life cycles like this, be solely seen in small living things, when patterns are echoed throughout nature.
Maybe I think to much with a fanciful slant lol.
yes it is hair like … the same hair like particles that allow quantum entanglement is exactly what you are looking for … i have made this statement many time
