    Reminder, that the furthest man made spacecraft right now is the voyager that started 46 years ago in 1977. it is 18 lighthours away. Not a lightday, not a lightweek. No a lightmonth. Not a light year. Not 60 lightyears. 18 lighthours in 46 years. One human lifetime is around 24-28 lighthours, in voyagers speed.

    If we want to reach a system that is 60 lightyears away, we need to astronomically advance our technology for propulsion technology and long time human space flights. Bone and muscle loss is a real problem when staying in space even for relativity short time.
