Every time at night when I let a video play on without paying attention, this damn interview is always the next to play in que. Wtf.

Thanks for having me on Lex, and for such a deep and thoughtful discussion.

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

This has to be your best podcast ever. Great guest. So informative and brilliant questions asked.

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’m so proud of humanity that 4.6M brilliant people have watched this podcast! 🥰

They are both so articulate and thoughtful, but also both so good at having a back and forth conversation. It was a compelling watch.

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.

One of the greatest collabs ever. Cool Worlds is hands down one of the best space content on youtube.

I’m so happy I found this!!! I owe Lex so much. He has enriched my life

I've got to say he's like the most watchable guy to listen to in terms of explaining science and the nuances on why certain fringe ideas don't hold enough water. This is one of the most enjoyable episodes of yours Lex. Thanks!

YESSSS I’ve wanted Prof. Kipping on for ages! This is gonna be a GREAT episode. So exited. Thank you Lex.

A 4-hour podcast to get through the weekend..... Lex lex lex what a savior

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

I thought the thumbnail was lex with a beauty filter on

I can't put into words how excited I am to listen to this. Cool Worlds and Lex together at last.

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

Bring him back more. He's amazing. So engaging. More engaging than watching a movie.❤
