If it is just a probe that blasts past, that does not count as interstellar travel. There would be very little left of a vehicle after being blasted by relativistic hydrogen nuclei for 3M years on its way to Andromeda. And, who would be listening for its report 6M years later, if it could get to Andromeda intact? Or even 500,000 years later, from one of the Magellanic Clouds? It would make sense to gather up your whole civilization and set out at a statelier pace, perpendicular to the galactic plane, to get clear of the numerous hazards that all threaten to sterilize your whole solar system when you are in the thick of a galaxy. Then it wouldn't matter if it took a million years to get clear. Probably you induce a polar jet from the sun for propulsion, and bring the whole solar system with you. (You would leave the Oort cloud behind, sadly.) |
