Extraterrestrial: The First Sign of Intelligent Life Beyond Earth by Avi Loeb

4.0

While the main topic of discussion is ‘Oumuamua, the weird interstellar object that slingshotted around the Sun in 2017, Loeb uses the opportunity to push for less dogmatism in astronomy and science and in particular, challenges scientists to rediscover their childhood curiosity. Maybe ‘Oumuamua is a natural object unlike anything we’ve seen before but why not invest in “Astro-Archaeology” and the search for bio- or technological signatures of other civilizations? This was a fun read even if a bit speculative.
