| 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, |

| 1:13.3 | while keeping in mind that 10,000 years is longer than all of recorded human history, |
