0:00.0	Hello, SFIA audio listeners. In this month's Nebula exclusive, big alien theory,
0:05.2	we're asked at 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,
0:15.1	check out go.nebola.tv slash Isaac Arthur and use my code, Isaac Arthur.
0:28.0	What would it be like to live on a planet where every step feels like carrying the weight of the world on your shoulders?
0:38.2	Over the years, we've explored the possibilities of settling strange new worlds, from the low-gravity planes of Mars to the weightlessness of space stations.
0:40.6	What about the heavy hitters of the cosmos?
0:43.2	Planets where every step feels like lifting a border.
0:46.7	Today we dive into high gravity worlds.
0:49.9	What would life in a high gravity environment be like?

1:08.6	non-planet cases like white dwarfs.

1:19.5	buttons.
1:21.1	From the outset, we need to recognize that life on a high-gravity world would be rough for
