Summary

Is it possible the Earth might be separated from the Sun or the Sun go out? And if so, could we survive under an eternally dark sky?

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.nebula.tv slash Isaac Arthur and use my code, Isaac Arthur.

0:28.3	They say there's nothing new under the sun, but what if someday Earth was flung away from our
0:33.8	sun?
0:35.1	So today we're going to be asking what would happen if Earth got ejected from its orbit around our sun, and if we could survive in the depths of our Sun. So today we're going to be asking what would happen if Earth got ejected from its orbit
0:39.1	around our Sun, and if we could survive in the depths of interstellar space.
0:43.5	As we will see today, this possibility is not as unlikely as it sounds, nor as inevitable
0:49.2	or doom as folks would tend to think, particularly from non-natural events like us intentionally moving
0:54.9	our planet, which we were also discussed today. To begin with, there have been frequent
1:00.3	arguments about what planets actually are for a couple centuries now, which tends to interfere
1:05.3	with the count. But while the number of objects we classify as planets might change, we generally accept that the objects
1:12.2	themselves do not, but this isn't entirely true, and indeed if you skip backaways, we
1:18.7	would find the planets have changed in their number and their properties, and indeed some
1:23.7	researchers believe that at some point in the early days, the solar system may even have
1:28.1	had some super-Earths, planets more massive than Earth, but less than Neptune, which clearly
1:33.6	are not around anymore. We looked at those recently and how capital they might or might not be,
1:39.5	and our solar system would be a very different place indeed if we'd had them and had kept them, and we seem to be a bit of an anomaly in that most of the other solar system would be a very different place indeed if we'd had them and had kept them,
