The Fermi Paradox and Cosmic Archaeology
27:26 - 30:54 (03:27)
The Fermi Paradox arises from the contradiction between high estimates of the probability of the existence of extraterrestrial civilizations and the lack of evidence for, or contact with, such civilizations. This podcast explores the potential for cosmic archaeology and the search for other civilizations in the universe.

If extraterrestrial civilizations exist, and they were expanding slowly, our sky would be full of vast spheres that were full of activity.

Summary
If extraterrestrial civilizations exist, and they were expanding slowly, our sky would be full of vast spheres that were full of activity. The last parameter, speed, comes from the fact that when we look in the sky, we don't see them.

The next 10 million years is a short time on the cosmological scale, but an interesting moment when we start expanding, and a bunch of other alien civilizations might arrive at this moment after passing all the hard steps.

PodcastLex Fridman Podcast
In this episode, the hosts discuss the possibility of extraterrestrial life and how scientists search for it by using the speed of the radius growth and expansion of the universe, and how the evidence that is present suggests that aliens may be moving really fast, which makes them almost invisible until they are here.
