Summary

Mankind's future is among the stars, but not necessarily on other planets. Instead we might forge giant space stations that are entire artificial worlds, and today we'll explore some of those megastructure designs, like the McKendree Cylinder, Bishop Rings, Banks Orbital, Topopolis, and more.

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.
0:10.0	To hear it and every episode early and add free, plus hours of bonus content, check
0:15.0	out Go.nebola.tv slash Isaac Arthur and use my code, Isaac Arthur.
0:20.0	This video is sponsored by CuriosityStream.
0:23.3	Get access to my streaming video service, Nebula, when you sign up for CuriosityStream
0:28.1	using the link in the description.
0:30.7	We often talk about building large rotating space stations for people to live on in the
0:35.4	future, but just how big can we go?
0:39.9	So today we'll be looking at some truly enormous space habitats that we might construct
0:43.8	in the distant future, but maybe not too distant.
0:47.2	Our big four structures to look at are the Bishop Ring, the McKendry cylinder, the Topopolis,
0:52.4	and the Banks Orbital. These occupy the size range in between the O'Neill cylinder, the Topopolis, and the Banks Orbiter.
0:54.4	These occupy the size range in between the O'Neill cylinder, which we've discussed so often
0:58.5	before, a structure big enough to house around a million folks with lots of Elbowroom,
1:03.2	and the Niven Ringworld, which has about a million times the living space Earth does,
1:07.7	and you can see both of those episodes for details on them.
1:15.7	Last week we looked at graphene, the super strong material whose discovery, along with carbon nanotubes, opened the door for seriously considering building such behemoth structures using
1:20.3	known science.
1:21.7	You can check that episode too for details, but the key thing about graphene is that it's
1:26.2	hundreds of times stronger than steel, and
1:28.4	thus can be used to make much larger radius habitats when used in conjunction with other materials.
