A new scientific theory says that the universe could have seven dimensions.
A new idea says that the universe might be a lot more complicated than we thought. A group of scientists says that there are three more hidden dimensions that could change how we think about physics. These dimensions are in addition to the four we already know about: length, height, depth, and time.
The concept is not entirely novel in theoretical physics; however, this model presents an alternative methodology for addressing one of the most significant scientific enigmas: the information paradox.
This issue emerges when attempting to harmonize the principles of quantum mechanics with the characteristics of black holes. These laws say that information can never be lost. Stephen Hawking's work in the 1970s, on the other hand, showed that black holes give off radiation and can eventually disappear completely.
Herein lies the main paradox. As researcher Richard Benczak explains, “Imagine you throw a book into a fire. The book will be destroyed, but in principle you can reconstruct every word from the smoke, ash, and heat: the information does not disappear; it is merely dispersed.”
However, if the black hole were to disappear completely, that information would be lost forever, which directly contradicts the laws of quantum mechanics.
The new theory proposes a radical solution. According to this model, spacetime not only curves, as Albert Einstein described, but can also warp thanks to invisible extra dimensions. This phenomenon introduces a concept known as "warping," which is key to understanding the ultimate fate of black holes.
According to researchers, when a black hole evaporates to enormous sizes, its seven dimensions become entangled, forming a kind of "knot." This process prevents its complete disappearance and results in the emergence of extremely small but stable remnants, capable of retaining all the information it absorbed.
This object, called a "torsion-stabilized residue," would be billions of times smaller than an electron, but it would act as a permanent archive of information, thus resolving the paradox.
Moreover, this theory may have deeper implications. Scientists suggest that these hidden dimensions could be linked to the Higgs mechanism, which gives particles their mass, and even to the mysterious dark matter that makes up about 27% of the universe.
However, proving this hypothesis will be extremely difficult. Particles associated with these extra dimensions would be far beyond the detection capabilities of current facilities, even those like the Large Hadron Collider.
Currently, researchers hope that future observations of the cosmic microwave background or primordial gravitational waves will provide evidence of this.
