Unattainability of the Trans-Planckian regime in Nonlocal Quantum Gravity
arXiv:1912.01878 · doi:10.1007/JHEP09(2020)056
Abstract
Based on the ultraviolet asymptotic freedom of nonlocal quantum gravity, we show that the trans-Planckian energy regime is unattainable in laboratory experiments. As physical implications, it turns out that the violation of causality, typical of nonlocal field theories, can never be detected in particle accelerators, while the asymptotic freedom of the theory provides an elegant solution to the so called trans-Planckian cosmological problem.
