Can the journey be completed within the lifetime of a human adult?
Assuming we have got around little problems like having an adequate form of propulsion, shielding from radiation, and avoiding deadly collisions with milligram sized dust particles.
Let's say our engines can provide constant acceleration then deceleration at 1g.
If the return journey can be done within the travellers lifetime, then will there be anyone still alive on Earth who they knew before departing?, or not so because those on Earth will have aged relatively faster than the travellers.
