Could this actually work?

Let's assume, for a moment, that it was possible to generate a black hole at a fixed distance from a space craft. The theory is that the black hole would draw the ship forward. Since the black hole is generated from the ship itself, it would remain the same distance away while pulling the ship after it.

Now I'm no physicist, but I believe that such an arrangement would violate a couple of laws of physics. Comments?

The first thing that comes to mind is what makes the black hole keep moving from the ship as it approaches? There is a very strong gravitational force between the black hole and any matter around it. So it would require a very strong force to overcome that. And such a force would in fact be pushing them away from each other.

That of course completely disregards the impossibility of your initial premise, that one could create a black hole at will.

The force that keeps the black hole the same distance from the ship would have to be at least as strong as the force that draws the ship towards the black hole. The two forces would negate each other.

This is not that different then trying move a sailboat by putting a large fan on the deck to create a wind.

If the ship could stay beyond the Event horizon but use the gravitational force as energy to travel. bodies in space including black holes are always in motion. now the problem was how do you steer the black hole in the direction you wish to travel. or you could use the Blackhole's gravity in a slingshot maneuver.

How do you propose generating a black hole?
