Unattainability of the Trans-Planckian regime in Nonlocal Quantum Gravity

TL;DR

This paper demonstrates that due to the ultraviolet asymptotic freedom of nonlocal quantum gravity, reaching the trans-Planckian energy regime is impossible in experiments, resolving related cosmological issues.

Contribution

It shows that the trans-Planckian regime cannot be accessed experimentally and that nonlocal quantum gravity's asymptotic freedom solves the trans-Planckian cosmological problem.

Findings

Trans-Planckian energies are unattainable in labs.

Causality violations in nonlocal theories are undetectable in accelerators.

Asymptotic freedom addresses the trans-Planckian cosmological problem.

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.
