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. |

0:24.3 | Maybe invading aliens won't show up with laser guns blazing, but instead making an |
