Maybe we could travel without bodies. Ala Lovecraftian astral travel or whatever. I mean you couldn't ship matter like that but for everything else it might work just fine.
Astral projection isn't Lovecraftian per se (fhtagn), but it's an interesting thing to ponder from a hypothetical / fictional perspective.
At best we'll be able to send out probes. Maybe, but this still feels science fiction too, we can harness quantum entanglement for long distance instant communication.
In his books, one way of travelling was to switch souls with a creature on another planet. Apparently it worked very well. Though managing a new set of limbs and senses could be difficult.
