” While these findings are initial, they supply a strong structure for more detailed investigations as we continue to collect information from our gamma-ray and neutrino telescopes. Even if future data were not to confirm this result, our findings would still offer stringent limits on the parameters of relevant designs, which would currently represent a uncommon and notable action for quantum gravity research,” adds Amelino-Camelia.
Recommendation: “Could quantum gravity decrease neutrinos?” by Giovanni Amelino-Camelia, Maria Grazia Di Luca, Giulia Gubitosi, Giacomo Rosati and Giacomo DAmico, 12 June 2023, Nature Astronomy.DOI: 10.1038/ s41550-023-01993-z.
New research study provides preliminary proof supporting a quantum gravity model which recommends that the speed of ultrarelativistic particles decreases with increased energy. The study utilized information from the Fermi telescope and the IceCube Neutrino Observatory to validate the theory. The findings mark a considerable advancement in the field of quantum gravity.
Researchers have actually reached a substantial turning point in the field of quantum gravity research study, finding preliminary statistical support for quantum gravity.
In a study published in Nature Astronomy on June 12, a team of scientists 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 ultrarelativistic particles reduces with rising energy. This effect is expected to be extremely small, proportional to the ratio between particle energy and the Planck scale, however when observing extremely remote astrophysical sources, it can collect to observable levels. The examination used gamma-ray bursts observed by the Fermi telescope and ultra-high-energy neutrinos spotted by the IceCube Neutrino Observatory, evaluating the hypothesis that some neutrinos and some gamma-ray bursts may have a typical origin but are observed at various times as a result of the energy-dependent decrease in speed.

” By combining data from IceCube and Fermi, we discovered preliminary evidence supporting quantum gravity designs that forecast this impact. This marks a considerable milestone in the field of quantum gravity research study because it is the very first time that such a level of quantum gravity-supportive analytical evidence is discovered,” states corresponding author, Professor Giovanni Amelino-Camelia of the University of Naples on behalf of the group.
