-
- Technology
Avi Loeb, Professor of Science at Harvard University, joins us to discuss a recent interstellar visitor, if we've already encountered alien technology, and whether we're ultimately alone in the cosmos.
Topics discussed in this episode include:
-Whether 'Oumuamua is alien or natural in origin
-The culture of science and how it affects fruitful inquiry
-Looking for signs of alien life throughout the solar system and beyond
-Alien artefacts and galactic treaties
-How humanity should handle a potential first contact with extraterrestrials
-The relationship between what is true and what is good
