This is how I relax in the face of possibly terminal illness. Knowing people like these two beautiful humans exist and are trying their best to keep an eye on the ball… just gives me an almost religious sense of hope for the future… in the face of a very uncertain future, that’s truly a gift. I aim to repay that gift in any way I can, big or small, to my very last breath. If you’re reading this in the future, my fellow archaeologists of the weird and wonderful, then know that I love you. Whoever and whatever you are.

OMG! Prof Kipping! I watch "Cool Worlds Lab" for years now and I'm beyond happy that he could spare some time for Lex and us. Thank you so much!

I am 56 yr old, and these podcast blow my mind. When I was in school, there was no way possible to hear conversations like these. A basic science class with a average educated teacher was not really stimulating. Lex gets extremely fascinating people on the cutting edge everything you could imagine and probably never imagined. I kind of sad that missed out conversation like these.

It's easy, I see Lex Fridman + aliens, I play click. Nearly 4 hours of podcasting, count me in!

David Kipping is a very good example of intelligent life as a creation of the universe. I really wish more people were as kind and smart as him

Easily the most comprehensive and interesting astrophysicist I’ve heard on any podcast. Well done.

I've been listening to Cool Worlds for years now. Great to see you guys have a conversation together.

Love Carl Sagan's ending quote. THANK YOU Lex for a deeply complex interview.
