I was trying to explain why the arguments saying it's impossible are inconclusive and we shouldn't throw out the possibility too quickly, but I'm afraid I didn't make my case very well. This video is a second attempt. Hopefully this time it'll come across more clearly! 📚 Buy my book ➜ https://amzn.to/3HSAWJW 💌 Support us on Donatebox ➜ https://donorbox.org/swtg 👉 Transcript and References on Patreon ➜ https://www.patreon.com/Sabine 📩 Sign up for my weekly science newsletter.
