A new crystal, capable of bending light like a black hole, is arousing keen interest in the scientific community. This feat, described as “pseudogravity”, opens the door to applications in fields as diverse as 6G communication and the study of quantum gravity (Quantum gravity is a branch of theoretical physics attempting to unify…).
The discovery, published in the journal Physical Review A, reveals a photovoltaic crystal capable of simulating the effect of light passing near black holes and other ultra-dense celestial objects. Kyoko Kitamura, professor at the University’s Higher School of Engineering. the objective is…) Tohoku in Japan, and his team succeeded in modifying the structure of these crystals to observe this deviation of light. The interest is multiple. On the one hand, this makes it possible to envisage wireless information transmission at ultra-high speeds, exceeding 100 gigahertz. On the other hand, this discovery could contribute to the study of quantum gravity, a theory (The word theory comes from the Greek word theorein, which means “to contemplate, observe,…) aimed at reconciling quantum mechanics (Mechanics quantum is the branch of physics which aims to study and…) with the theory of Relativity (This article deals with the theory of relativity through the ages. In physics, the notion of… ) Einstein’s general.
Masayuki Fujita, associate professor at Osaka University in Japan, emphasizes the academic importance of this research. According to him, photonic crystals could reproduce gravitational effects, thus opening new perspectives in the field of physics (Physics (from the Greek φυσις, nature) is etymologically the…) of gravitons.
The existence of the graviton, a hypothetical quantum particle responsible for the gravitational force, remains to be confirmed. However, this advance could play a role in understanding this still theoretical entity.
