Is there a science fiction universe that explores a hypothetical warp drive that lets you travel very far relatively quickly, but the travel is only possible with simultaneous backwards time travel that's proportionate to the distance traversed? So you can hop across star systems but can't do a roundtrip A -> B -> A without significantly shifting time from the point of view of A backwards (irreversibly from the point of view of the traveler).
- An Earth telescope will see the destination as it was when I left
- It will take another year to see me arrive
So in a way that's already happening because I'm traveling quite quickly - twice as fast as it seems from Earth's perspective - and I arrive in what appears from Earth to be the past.
