What if it hits instead of passing by?

Honestly, I have no idea lol.
They compare the mass of it to an asteroid, but that's a pretty big range of possible masses. Assuming it's the mass of a small, "survivable" asteroid, it wouldn't burn up in the atmosphere since it's atom sized.
If a regular asteroid of the same mass is like a sledgehammer, I would imagine the similarly-massed, atomic-sized black hole would be like a bullet?
But I'm just throwing stuff at the wall with that guess.
Probably the same as an asteroid of equivalent mass at impact.
Except an asteroid stops when it impacts the surface. Since a microscopic black hole would absorb the atoms directly in its path, there would be no "impact" where it imparts all its kinetic energy to the surface.
The article links to another article describing the effect of getting hit by a primordial black hole. At their typical assumed speed theyโd pass through a planet without stopping, but the momentary distortion caused by their passage would be enough to kill a person in its path.
What if this is what causes strokes? Black holes yeeting through your head and snatching a few grams of grey matter, causing a bleed and stroke.
We're estimating once a decade. Not thousands a day.
Could the estimates be wildly off? Yes. But that's still pretty wild conjecture lol.
They compute the odds of a human ever getting hit by a PBH in the lifetime of the solar system, and itโs... considerably less than the odds of getting a stroke.
New fear unlocked.
Experimental evidence please...
There have been SO MANY hypotheses for dark matter without experimental evidence. For one, we don't even have evidence yet of dark matter being actual matter instead of being modified gravity.
Sure, theoretically dark matter seems a lot more likely than modified gravity, but still... We need that evidence badly.
