Summary

Science Fiction has shown us humanity exploring the stars at hundreds of times faster than light speed, but what if the fastest ships we can make never even reach a hundredth of light speed? Can we still settle the galaxy and what will that colonization entail?

0:00.0	Hello, SFIA audio listeners.
0:02.5	In this month's Nebula exclusive, Big Alien Theory,
0:05.2	we're asked at the reason alien civilizations might be rare
0:08.0	is because most aliens are huge.
0:10.5	To hear it and every episode early and ad-free,
0:13.3	plus hours of bonus content,
0:15.1	check out go.nebola.tv slash Isaac Arthur and use my code, Isaac Arthur.
0:20.0	This episode is brought to you by Brilliant.
0:23.0	Benjamin Franklin once said,
0:25.1	He that can have patience can have what he will.
0:28.3	And when it comes to space, it means having a lot of patience.
0:32.5	But the reward is an entire galaxy.
0:38.3	Yeah. is an entire galaxy. So science fiction often shows us faster-to-lighted spaceships, taking pioneers to new
0:49.3	colony planets halfway across the galaxy in mere months.
0:53.3	And on the show we often discuss how FTR
0:55.6	probably won't be an option, but we can still colonize space. It will just take us longer,
1:01.5	requiring generation ships that might move at 10 or 20% of light speed, needing a generation
1:08.4	or two to get to the nearest stars and maybe several to get to a preferred
1:12.5	candidate system. However, while known physics certainly allows such ships, it relies
1:18.3	on a lot of optimistic solutions to problems, not least of which is if it is really possible
1:24.7	to build a ship that could survive moving through space at truly
1:28.2	relativistic speeds.
