Yeah, it's a bit of a worry!!!. Going to mean you can't trust your observations of far flung parts based on what you know of the physical laws, because you have no idea what the laws in those parts are going to be like.
Just thought of something funny....here you go cruising along at c out near the boundary of our corner of the universe, when you have to take a detour into the next section because of a "field" of black holes in your way. Then suddenly you find yourself thousands of light years away because the speed of light barrier doesn't apply in this section!!!!
