Not really. What was stated above by another poster is speculation regarding micro black holes, and even had they ever existed, they would be LONG gone by now through evaporation that results from emitting Hawking Radiation, as his own source (unlinked wiki) actually states.
Would you say that Hawkin Radiation is produced by Quantum Tunneling?
Hawkin Radiation defined as :: The thermal radiation predicted to be spontaneously emitted by Black Holes...It arises from the steady conversion of Quantum Vacuum Fluctuations into pairs of particles, one of which escaping at infinity, while the other is trapped inside the Black Hole Horizon..
In simple terms, one of the particles escapes from the enormous pull of the Black Hole, whilst the other particle is kept trapped inside it ..
