MEXICO CITY.- An investigation has discovered some surprising properties in graphene that could reveal the existence of a universe parallel to ours, resolve doubts about the cosmological constant and explain how elementary particles were formed.
According to the article published in Lavente-EMV, many things could be expected from graphene, but it is difficult to imagine that it would give rise to a cosmological model according to which our universe would be one of two closely linked parallel universes.
That cosmological model has been an unexpected finding, emerging after two University of Maryland researchers discovered a surprising property in graphene.
According to them, this property of graphene suggests that our universe would be coalescent, that is, it would be made up of another universe that constantly interacts with ours.
Graphene is a two-dimensional nanometric material, made up of a layer of carbon atoms arranged on a uniform surface that is slightly undulating. Its structure shows a hexagonal atomic configuration.
It is the most resistant material in nature that has not gone unnoticed: the physicists Andréy Gueim and Konstantin Novosiolov were awarded the Nobel Prize in Physics in 2010 for their revolutionary discoveries on graphene.
Now it has been two other physicists, Alireza Parhizkar and Victor Galitski, who have once again struck a chord with graphene. They found that when a curved and stretched sheet of graphene is placed on top of another equally curved sheet, a new pattern emerges from that interaction that has a direct impact on electrical conductivity.
Physicist Andrey Feldman points out in Advance Science that the physical properties of a single layer of graphene depend on the size of its elementary hexagonal pattern.
In bilayer graphene, if the layers are deformed relative to each other, a new periodic structure called a moire pattern is produced: its length scale can display orders of magnitude larger than the size of the original hexagons.
As a result, the energy levels of the electrons in graphene change with respect to their energies in a single layer and this property, according to Parhizkar and Galitski, could have cosmic dimensions.
In other words, both authors suggest that, in experiments on the electrical properties of stacked graphene sheets, special energetic conditions prevail that are always repeated, producing results that resemble small universes. In other words, they say, there could be a parallel reality to ours that is revealed through graphene.
According to these authors, some phenomena in cosmology and elementary particle physics could be the result of two almost identical coalescing worlds interacting with each other, as occurs in graphene layers.
If this assumption is correct, one of the issues that could be resolved thanks to graphene would be the discrepancy between the measured value of the cosmological constant and the theoretical estimate of its quantity.
“We do not claim that our result solves the problem of the cosmological constant,” explains Parhizkar in this regard. “That is a very arrogant statement, to be honest. What we are proposing is that if we have two universes with huge cosmological constants and we combine them, there is a possibility that we can obtain a uniform cosmological constant”.
The authors also argue that their model not only provides a plausible solution to the cosmological constant problem, but also predicts cosmic inflation, the ultrafast expansion of the universe that occurred immediately after the Big Bang.
The cosmological model based on graphene would also explain the Higgs mechanism, a type of superconductivity that occurs in a vacuum and that explains the origin of the mass of elementary particles, as well as the Higgs boson, discovered in the Great Collider of Hadrons in 2012, and that helps all particles have mass.
Finally, the model not only includes already observed or hypothetical phenomena, but also some predictions about new interactions between elementary particles, which could perhaps be observed in the future, according to the researchers.
The team intends to continue studying their theory, hoping to find a way to test it experimentally and, perhaps, revolutionize particle physics and astrophysics once again.
