Summary

The galaxy is an immense place, with billions of solar systems to colonize, and interstellar voyages to even nearby stars can take centuries. In order to explore and settle those new worlds, we may wish to take advantage of a type of generation ship that stops at planet after planet, colonizing each in turn, and entire colonial fleets that grow as they venture outward from Earth, creating new spaceships as often as terraforming new worlds.

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, check out
0:15.5	go.nebola.tv slash Isaac Arthur and use my code, Isaac Arthur.
0:20.6	This episode is brought to you by Skillshare.
0:24.1	It seems like the galaxy is a cold and bale in place, but in truth, it's a fertile garden
0:30.4	waiting for us to plant it.
0:44.6	So today we return to the Generation Ship series to look at what I tend to consider one of the more likely scenarios for colony ships to other solar systems.
0:50.4	Under our current understanding of physics, the speed of light limits us to taking many
0:54.8	years to get to even the nearest stars, and even getting to a fraction of light speed is
1:00.3	quite difficult.
1:02.0	This means any pioneers looking to settle the galaxy are going to be old and gray before
1:07.2	arriving or long since dead.
1:10.2	As we mentioned back in the first episode, there's
1:12.7	essentially five core methods of getting around this issue. One of those is simply to settle
1:18.1	new wars with the descendants of the original crew, the classic generation ship. Another is to
1:24.2	freeze the crew and revive them on arrival, what we call a sleeper ship.
1:29.6	We also have the seed ship and the data ship routes we discussed last time in seeding the
1:35.0	stars, and these two have a lot of overlapping concept.
1:39.2	The default seed ship settles worlds by using machines to go there and tail form the world, and
1:45.8	potentially even to grow humans and vats from frozen embryos and raise them, while the
1:51.3	data ship contemplates a more digital approach, potentially simply bringing uploaded copies
