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,

1:35.9	Earth has a surface area of approximately half a billion square kilometers, or 200 million
