Unless Einstein is wrong, but if you're going to postulate that you're into Clarke's Third Law territory.
Maybe I'm missing something - but I fail to see how this is more of an issue than a jet going faster than the speed of sound and arriving before it's noise arrives.

And no - it doesn't violate relativity. Relativity never says that stuff can't travel faster than the speed of light through the universe. Quite the opposite. It says that nothing can travel through SPACE faster than the speed of light. It's already been proven that light sometimes travels marginally faster than the speed of light when it's affected by gravity - because the gravity itself warps space-time.
