Observation and point of reference, of course. Both impossible in a void as you described.

And yes, what is accelerating an object does matter. Even if light itself was accelerating the object, it would only go as fast as, not faster than light.

You're asking if something going slower than light can go faster than light. You figure out a propellent that's faster than light, and well, you'll have your answer won't you?
