Summary

Historically humanity has often taken shelter in caves or underground, and it is often thought we might do so again, on other worlds, in event of disasters, or simply because we run out of room on the ground above. In this episode we'll explore the concept of building underground, from simply subways and basements to advanced bunkers or entire cities beneath the Earth.

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.
0:20.4	This episode is brought you by Brilliant.
0:23.7	Humans have always needed protection from the elements, but nature provided limited shelter,
0:28.8	and, until we could build our own dwellings, the earth itself provided some of the best
0:33.4	sanctuary, perhaps it will again in the future too.
0:39.9	Living underground or in caves is nothing new to humanity, as the Flintstones can
0:44.3	attest, and today we're going to be exploring both how we could build expansive subterranean
0:49.2	colonies in the future and why we'd want to.
0:53.2	That's an important first point though, we aren't breaking new ground here, but exploring
0:57.8	new ways to employ existing technology and methods.
1:01.9	Even ignoring trivial examples like basements or mine shafts, most large cities have large
1:07.4	subterranean networks such as subways, sewers, piping, and cables, along with
1:12.7	their maintenance causeways, and a few even have underground commercial districts.
1:18.1	There's a lot of reasons why we don't typically house people and offices underground.
1:22.8	First, there's the cost issue.
1:24.8	Most buildings are only at ground level, and where they exceed
1:28.1	that, it's usually a second floor, an attic, and a single basement. Those mostly exist
1:33.5	because you have to dig down to make sure your foundation is solid, and you're usually
1:37.9	only digging into dirt and clay, not bedrock. Cost of excavation is huge, far more than building up to an equal height is,
