Summary

If the Universe is inhabited by older alien civilizations, those who have ventured out to the stars and colonized galaxies, we would expect to see a footprint of extraterrestrial activity. Could the many stars whose brightness has dimmed be indicative of Dyson Spheres or other Megastructures? Could the Cosmic Voids vastly bigger than any galaxy be the work of even greater and older starfaring species?

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,
0:15.1	check out go.nebola.tv slash Isaac Arthur and use my code, Isaac Arthur.
0:20.1	This episode is sponsored by Skillshare.
0:24.0	Alone in a dark forest, does the sudden hush of woodland critters frighten you?
0:29.0	Are you really alone?
0:31.7	There are a pair of fairly common reactions to any new astronomical phenomena.
0:36.6	The first is to see such an anomaly outside
0:38.7	our current understanding and assume its proof of alien life.
0:42.4	The second is seeing that anomaly and saying it is certainly of natural origin and any
0:46.7	suggestion to the contrary is absurd.
0:49.8	Now neither reaction exists in a vacuum.
0:52.7	Of course nothing does exist in the vacuum, which is
0:55.1	essentially our topic for the day, in an astronomical context, but also in a human context.
1:01.2	On the discussion of the existence of aliens, both reactions are from decades of folks
1:06.0	contemplating the topic of the Fermi paradox, the seeming contradiction between the sheer
1:10.7	size and age of the
1:11.7	universe, and the apparent absence of any other intelligent life in it. Those two reactions I
1:17.3	mentioned, this is aliens and this is definitely not aliens, aren't really the ground state of
1:23.1	either reaction, and indeed the second is more of a reaction to the first.
1:28.1	The first is generally initially simply intrigue, we've got something we can't explain,
