A new cosmological model suggests the existence of a parallel universe

Research 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.

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 coalescingthat is, it would be composed of another universe that constantly interacts with ours.

The graphene It is a two-dimensional nanometric material, composed 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 there have been two other physicists, Alireza Parhizkar Y Victor Galitsky, those 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 moire pattern: Its length scale can display orders of magnitude greater 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 ensure there could be a reality parallel to ours that is revealed through graphene.

coalescing worlds

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 cosmological constant and the theoretical estimate of its quantity.

“We do not affirm 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 combine them, there is a chance that we can get 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 the cosmic inflationthe ultrafast expansion of the universe that took place immediately after the Big Bang.

The cosmological model based on graphene would also explain the higgs mechanisma type of superconductivity that occurs in a vacuum and that explains the origin of the mass of elementary particles, as well as the Higgs’ Bosondiscovered at the Large Hadron Collider in 2012, and which helps all particles have mass.

Promising prospects

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.
