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 add free, plus hours of bonus content, |
0:15.1 | check out go.nebola.tv slash Isaac Arthur and use my code, Isaac Arthur. |
0:20.5 | This episode is sponsored by Brilliant. |
0:23.8 | It's always amazing to watch a rocket take off from the ground and fly up through the clouds into space, |
