Relevant content, engaging and informative

Perfect podcast for those who want engaging, straight-up science content without all the extra cheese. Great guests and topics. Seems long - but never feels like it when you’re half way in.

Gimme!

More! David Kipping has joined Sagan and Cox and Thorne and Rovelli and Tyson and Feynman on my list of so-fun-blow-your-mind-and-inspire-you stuff to listen to. I know you’re busy, but give us more here!

Love it

Big fan of the YouTube channel. Didn’t know Prof. Kipping and his team had a podcast until he mentioned it on StarTalk. If you like either of those then this will be a hit with you.

Great conversation!

I was so excited for this podcast and it did not not disappoint. David is a great conversationalist and asks well timed thought provoking questions that keep a good pace throughout. The presentation style kept me very engaged and was overall a fantastic experience. I can’t wait to for new episodes!

One of a kind

I have been listening and studying with Cool Worlds since discovering it a few years ago on YouTube, and ever since it has been one amazing ride. I’ve learned more spending small moments of time with the doctor and his subjects of the cosmos, time and beyond than I ever did in any textbook or classroom. This podcast is just another extremely encouraging and inspirational extension of everything this platform continues to produce. Thank you so very much! It will definitely get you thinking about all aspects of the universe!
