COMMENTS, REPLIES AND NOTES: A note on the innocuous implications of a minimum length in quantum gravity
Abstract
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 Planckmass black holes.
