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

The speaker, a Harvard scientist, discusses his book 'Extraterrestrial' which explores the discovery of Oumuamua, an object from outside the solar system. Discovered in 2017, Oumuamua exhibited unusual characteristics, such as a flat shape and a push away from the sun without a cometary tail, suggesting it might be artificial. The speaker compares this to finding a plastic bottle on a beach, indicating a civilization. He emphasizes the importance of learning from potential extraterrestrial intelligence, as the Sun-Earth system is common in the Milky Way.
