Yes and the Trinity test was supposed to set the atmosphere on fire.
Oddly, it just blew up.
If a black hole was indeed generated, it would be extremely miniscule. The lifetime of a black hole is proportional to its mass raised to the fourth power. Such a black hole, with not even a microgram of mass, would evaporate almost immediately. Maybe, just maybe, the bubble chamber will capture its trail as it evaporates into oblivion.
This is tied in with the Hawking Radiation.
