Even at (way) sub-light speeds, it's probably possible. Whether it's automated self-replicating ships (possibly carrying humans as gene sequences), or generation ships (seems pretty hellish!), a number of people have estimated mathematically that it's doable. Estimates vary wildly, of course, as there are many unknowns, but basically exponential growth gets unintuitively fast. Some links (there are many more pages too):

- Udik 7y agoThis is not "travelling" any more. This is sending spores hoping they will take root somewhere, but they will be forever disconnected from us, in space and, more importantly, in time. What's this mania you have of disseminating yourself? Even if you build ships that carry human genes sequences and send them on a million years trip, who is going to benefit? The sequences you sent?

- bavell 7y agoI can confirm it's both wildly relevant and insightful :)
- randallsquared 7y ago> What's this mania you have of disseminating yourself? Life. It's what living beings do. If some group of living beings stop doing it, there are fewer of them, later.
