What would happen if one of these tiny black holes hit Earth? The article doesn't really talk about it.
Absolutely nothing.
Also not sure why they wouldn't evaporate nearly instantaneously. Sounds to me like more dark matter bunk.
Passing near the earth, we’d get some strange tides. Passing through the earth, it would eat earth.
Nonsense. The event horizon on such things is incredibly small, as is the mass vs. that of Earth.
You don’t need the event horizon, you just need local gravity around 1G. For the masses described in the article, that radius is from hundreds of meters to 10s of kilometers.
Which still wouldn't do what you suggest. The mass is the same, so it has the same effect from a distance. Unless by "eat earth" you meant it would take in dirt until it suck to the core, still about the same mass.
