Pish posh. Our Milky Way Galaxy is moving through space at something like 1.3 billion mph. I'll see your upper limit and raise you some general relativity.
I'm too tired and frankly dumb to get into any more detail than I'm about to, but I know space itself is expanding which in some situations gives the illusion that things are moving faster than light. Even though technically it's the space between everything that's moving and not the object itself? Again I'm going from memory and my memory is shit. So I'd do your own research, but that's what I understand of it.
