The new research provides preliminary evidence supporting the quantum gravity model, which shows that the speed of ultra-small particles decreases with increasing energy. The study used data from the Fermi telescope and the IceCube Neutrino Observatory to validate the theory. The results show significant advances in the quantum gravitational field.
Researchers have reached a milestone in the field of quantum gravity research, finding the first statistical support for quantum gravity.
In a study published in natural astronomy On June 12, a team of researchers from the University of Naples “Federico II”, the University of Wroclaw, and the University of Bergen examined a quantum gravity model of particle propagation in which the speed of supercorrelated particles decreases with higher energy. This effect is thought to be very small, proportional to the ratio between the particle energy and the Planck scale, but when very distant astrophysical sources are observed, these effects can increase to observable levels. The investigation, using gamma-ray bursts observed by the Fermi telescope and high-energy neutrinos detected by the IceCube Neutrino Observatory, tested the hypothesis that some neutrinos and gamma-ray bursts may have the same origin but be observed at different times. As a result of the decrease in energy dependent speed.

“By combining data from IceCube and Fermi, we have found preliminary evidence to support the quantum gravity model that predicts this effect. This marks an important milestone in the field of quantum gravity research as it is the first time such a level of statistical evidence has been found. was found to support quantum gravity, said the corresponding author, Professor Giovanni Amelino Camellia of the University of Naples on behalf of the team.
“While these results are preliminary, they provide a solid basis for more detailed investigations as we continue to collect data from our gamma-ray and neutrino telescopes. Even if future data do not confirm this effect, our findings will still place tight constraints on the relevant model parameters.” , which would indeed represent a rare and extraordinary step for quantum gravity research,” added Amelino-Camellia.
