| 0:00.0 | Hello, SFIA audio listeners, in this month's Nebula exclusive, Big Alien Theory, |
| 0:05.0 | we're asking the reason alien civilizations might be rare is because most aliens are huge. |

| 0:30.9 | In the future, the brightest empires will be born around dying stars. |
| 0:49.1 | Yeah. will be born around dying stars. Colonizing other star systems in this galaxy is probably one of the most foundational topics we cover on this show, and a few weeks back we looked at colonizing red dwarfs, those smallest of stars which |
| 0:55.6 | outnumber all the other types of stars combined. I mentioned at the time that even though |
| 1:00.3 | they were the most numerous, they were far less bright, amounting to less than a percent of the |

| 1:11.9 | stars and I thought we should follow up looking at colonizing dwarf stars by looking at colonizing |
| 1:17.0 | giant ones too. As we will see today, such systems around giant stars may be crowded |
| 1:23.1 | with dozens of planets, all potentially habitable, and each taking decades or even centuries |
| 1:28.4 | to orbit their star. |
| 1:30.0 | However, as I was writing that sequel, I began feeling like it was a topic that needed |
| 1:34.0 | to be broken into a few episodes instead. |
| 1:36.8 | So this week is not just a sequel episode, but also the first of three episodes, or a second |
