npub1knzsux7p6lzwzdedp3m8c3c92z0swzc0xyy5glvse58txj5e9ztqpac73p (npub1knz…c73p) Interesting question... What would the impact of an asteroid mass black hole be on surrounding objects?
Their gravity would be too weak to impact most stuff strongly unless it got really close, so I expect they'd be really hard to detect. And they'd be tiny, like event horizons a cm or less across (maybe submicron even, I don't have a good intuition for Swarzchild radii).
But what would happen if, say, an ordinary asteroid of the same mass were to collide with one?
My gut feeling is that it'd be like a bullet hitting a piece of Styrofoam: such an extreme mismatch in density that the BH would fly right through the object, drilling a tiny pencil sized hole of material sucked into the event horizon, with very little impact to the broader object or momentum transferred to it.
