Summary

Without the Sun our world would be a frozen wasteland, and for this reason any efforts to colonize the galaxy must focus on huddling in the tiny oases of warmth around stars, separated from each other by enormous gulfs of interstellar space. But what if we could make our own stars at the places of our choosing? And can we merely mimic nature or create stars unlike anything which nature has formed?

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, check out
0:15.5	go.nebola.tv slash Isaac Arthur and use my code, Isaac Arthur. This episode is brought you by Audible.
0:23.2	We often discuss colonizing planets around distant alien suns, or building artificial habitats around our own sun, but building suns might be a stellar idea.
0:45.5	Yeah. a stellar idea. We spent a lot of time talking about making artificial habitats or entire worlds for humanity
0:51.8	to live on in the future, and I thought it was past time we talked about the suns that would light them and how we
0:58.2	can go about making those.
1:00.6	Now a point we often make about megastructures and artificial planets is that they hold
1:05.1	three critical advantages over planets.
1:08.3	First they use vastly less mass and material than a planet does for the same total
1:13.7	living area, because for the most part, there's no need to have your ground go more than
1:18.4	several meters deep, rather than several thousand kilometers like on a planet.
1:23.7	You can get a million times the living area out of a planet by turning it into tons of
1:28.2	rotating habitats rather than a big sphere, or by using something vastly more abundant
1:33.9	than rocks and metals to fill that sphere, like compressed hydrogen or helium, or black
1:39.3	holes made of those, or maybe even dark matter.
1:43.3	Second, you can build them wherever you want and to a customizable size and gravity.
1:50.1	There's only a fairly narrow window of both location and composition that's going to produce
1:55.2	a planet people can reasonably make habitable and Earth-like.
1:59.7	And third, you can get very exact with replicating
2:02.7	certain earth-like conditions on a megastructure. It would be almost impossible to find
