Isn't there a potential for net relative displacement and so thus couldn't (microscopic) black holes be a space drive? Is there a known inverse transformation

Isn't there a potential for net relative displacement and so thus couldn't (microscopic) black holes be a space drive? Is there a known inverse transformation for Hawking radiation, and isn't there such radiation from all things? Don't black holes store a copy of everything, like reflections from water droplets? PBS Spacetime estimates that there are naturally occurring microscopic black holes every 30 km on Earth. https://news.ycombinator.com/item?id=33483002 https://news.ycombinator.com/item?id=33483002 https://westurner.github.io/hnlog/#comment-33483002 https://westurner.github.io/hnlog/#comment-33483002 And ER=EPR: https://twitter.com/westurner/status/964069567290073089 https://twitter.com/westurner/status/964069567290073089 What are the critical conditions for naturally-ocurring and lab or particle-collider made black holes? Are there safety concerns, and how would that be perceived?
