Cool Worlds | Is 'Oumuamua Alien Technology? @CoolWorldsLab | Uploaded 3 years ago | Updated 4 hours ago
Three years ago, we detected the first interstellar object passing through the Solar System, `Oumuamua. Ever since, astronomers have been debating the origins of this strange body. Whilst many hypothesize an asteroid, the media is ablaze with the possibility that it could be alien technology. Join us today for a discussion of this theory and the counter-arguments proposed. Written & presented by Prof David Kipping. Thanks to Dr Sean Raymond for fact checking - check out his blog www.planetplanet.net and astro poetry book amazon.com/dp/B08LFZZWGZ
