# A note on the innocuous implications of a minimum length in quantum gravity

@article{Frampton2008ANO, title={A note on the innocuous implications of a minimum length in quantum gravity}, author={Paul H. Frampton}, journal={Classical and Quantum Gravity}, year={2008}, volume={26}, pages={018001} }

A modification to the time–energy uncertainty relation in quantum gravity has been interpreted as increasing the duration of fluctuations producing virtual black holes with masses greater than the Planck mass. I point out that such virtual black holes have an exponential factor arising from the action such that their contribution to proton decay is suppressed, rather than enhanced, relative to Planck-mass black holes.
