Summary

Interstellar travel is very time consuming, moving from star to star, but perhaps we could use stars themselves as spaceships, and move whole solar systems or even galaxies. Today we'll look at how to use Shkadov Thrusters, novas, supernovae, black holes and quasars to move through space, literal starships.

0:00.0	Hello, SFIA audio listeners. In this month's Nebula exclusive, big alien theory,
0:05.2	we're asking the reason alien civilizations might be rare is because most aliens are huge.
0:10.5	To hear it and every episode early and ad-free, plus hours of bonus content,
0:15.1	check out go.nebola.tv slash Isaac Arthur and use my code, Isaac Arthur.
0:20.3	This episode is sponsored by Audible.
0:23.7	For thousands of years, humans have sailed ships through Earth's fast oceans, navigating
0:29.3	by the stars.
0:31.1	Someday, we might sail the stars themselves. So today we return to the Generation Ship series to finish out our recent look at colony

0:51.2	As we mentioned earlier in the series, in Million Year Arc and again in Planet ships,

1:02.5	astronomical timelines, you have to plan for a level of redundancy that safeguards
1:08.2	your colonist survival, even if their society collapses and rises again
1:13.2	several times along the way.
1:15.9	A few centuries is a fairly fast trip to even nearby stars, and it's also a lot longer than
1:22.4	most civilizations have lasted, at least in the sense of continuity of goals and focus.
1:28.3	Now there are some exceptions to that, and one is where the goal or focus is simply survival,
1:35.3	as civilizations replaced or mutated with time keep basic goals like that, and if you're
1:41.3	on a generation ship, that mission is basically survival.
1:46.8	You aren't necessarily limited in options to only surviving the trip to a new system and
1:52.1	surviving that system's colonization, but close enough, that goal, colonization, can be
1:58.9	more easily maintained in the long term because it so closely mirrors
