Of course, planets and stars would be more like trying to push an NFL linebacker out of the way of your Cheerio...
If we are talking interstellar space it is uncharted space for anything smaller than star.
Considering our starship will be smaller than a great many objects that could be in our path I think traveling at greater than light speed would be extremely risky.
Planet size objects could be in our path and we would have no way of knowing and traveling a greater than light speed we would never know.
It would be an interesting equation however an object of infinite mass striking an immovable object.
Traveling through hyperspace ain't like dusting crops, boy! Without precise calculations we could fly right through a star, or bounce too close to a supernova and that'd end your trip real quick, wouldn't it?
There is no such thing as an immovable object in space.
Think of it in terms of competing gravity wells. Instead of the negative potential in front of you “pushing” the objects space/time out of the way, you’d “skim” around the rim of the heavier masses space/time curve...
