The question is about whether you think expansion speed(time) will be exponential or log or whether there will be bottlenecks. Assume timelines where humanity (or whatever it evolves into) survives long enough and still uses creation of new beings.

0 = Year 1961

A = First human born on other celestial body.

B = First human born outside Solar system.

C = First human born inside other Star system.

D = First human born on the opposite half-circle of Milky Way.

E = First human born in other galaxy.

F = First human born outside the Local Group.

G = First human born outside the Local Supercluster.

For the question use spaceship-local time. The time intervals that moving humans would experience.
