I think cyanydeez is misguided, what he means to say is known economics prevents..... Of course there is no physics preventing it

  > Of course there is no physics preventing it Physics arguably prevents this from being successful for journeys of any meaningful distance and carrying any meaningful payloads. PBS spacetime did a good video about this recently: https://www.youtube.com/watch?v=wdP_UDSsuro https://www.youtube.com/watch?v=wdP_UDSsuro It's not impossible, but it's a lot harder than most people think.

    That's a very good video, thanks for sharing. I think it does a great job of highlighting why meat crew on a single vessel is perhaps a difficult proposition. I think we need anyway a colonizing swarm, not a single ship. I know this goes into scifi territory, but I can imagine a scenario where compute based caretakers could take the seeds of a human civilization (hibernating or embryos) to a system with human compatible worlds. I would guess we would populate asteroids before other solar systems, and experiences from asteroid based colonies could probably be replicatable in most hospitable systems. You need to scout the system pretty well. And send many, many ships with multiple redundancies.

      In the future, a payload of perhaps several pounds will allow viral replication of a civilization from that. (Particularly since additional design information can be sent via radio waves.)
