I think gravitational effects would be noticed, an incoming black hole with, let's just say 12x the mass of the sun, would definitely shift some orbits (marginally), but enough for us to detect them. Since we aren't detecting anything (except for like, planet x, which could be a black hole?) Safe to assume there isn't one "near" but honestly I could be completely wrong lol

It's hard to think that from a far enough distance, it would give us more than a few centuries notice atleast?
I feel like if there was, even a sun mass object, within the oort cloud, we would 1000000% know it. So if a 12x mass black hole was moving towards us, surely we'd be able to detect it. When I say shifting orbits, I'm saying very marginally, not enough of a difference, but enough to be detected to where we know something big is headed toward us.
Jupiter has a very noticeable effect on the sun, and the sun is like, 99.8% of the solar systems mass. Surely a 12x black hole would affect something enough for us to detect. Our planets/sun would surely feel it from very far away, and Im sure we would be able to detect the increasing shift due to the black hole heading towards us
