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.
0:21.3	Space is enormous and may be home to many ancient civilizations besides ours.
0:27.0	What do we do if we realize we are no longer alone?
0:29.8	And it turns out, they are not coming here as friends.

1:09.9	or welcome our new alien overlords.

1:18.0	and that depends a lot on what their motivation is. Why have they invaded and what is their goal?
1:23.5	Some of these scenarios give us better chances than others. We'll explore why aliens might invade, and even consider the possibility that they might
