When traveling at fast speeds through the galaxy, would it be possible to identify where all the black holes were on your path? I know most black holes are identified by their affect on other nearby objects. But what would happen if it was all by its lonesome?
Would we be able to 'sense' it somehow before getting to close to be adversely affected by it? Or would we fly by, maybe getting close enough for it to deflects our course? And how much could it deflect a course (assuming you stay out of the event horizon)? Would it warping of space allow for Alcubierre drive like properties?
I guess I'd hate to get thrown into a sun because of a course alteration from a black hole, though getting caught in the event horizon wouldn't be much better. Can we detect these masses to avoid them at distance or do we need to take first trips much slower so we can scan for these anomalies and mark them for safe 'shipping lanes'?
