I think any big journeys like that will be one way trips. Probably
even to other stars within our own galaxy.

But when we are considering the far future, my thinking is that any
centuries long journeys will probably mean the whole civilization
deciding to move together. Especially when you factor in the mental
speedup of our future intelligences. If one actual year equals 50,000
years subjective life, then I doubt whether anyone will want to leave
the civilization for that long.

I suppose robot probes are possible, but the wait of millions of years
subjective time for a reply makes it seem hardly worth while.
