I've always been a proponent of that type of propulsion for ftl. I once asked a physics professor what the speed of gravity was;
"9.8 meters per second"
"No, sir, that's acceleration due to gravity on Earth in a vacuum. What is the speed of gravity itself?"
"I don't take your meaning."
"If we have an earth-sized object in a pure vacuum, and instantly introduce another earth-size object 100,000 miles away, how long would it take for their gravitational pulls to effect each other?
"Well, instantly, I suppose"
"What makes you say that?"
"Last I checked, we were working on inertia, why can't you ever ask topical questions?"
Maybe I like the sound of gravitic propulsion because I don't understand gravity, which makes as good an excuse as any for a sci-fi propulsion source.
