What a great podcast. Perfect blend of John’s philosophical take and Katie’s wonderfully vivid scientific explanation of cosmology. I am now going read Katies book and search for everything John Green has ever done. Can’t wait to hear more from both of these great personalities.

One I mean that’s crazy why didn’t they find earth like planets but they will find one earth like planets soon

Dig in and learn! Whether you have never delved into this kind of material before or even if you have, you will learn a lot. Katie Mack is SO good at conversationally explaining some really mind blowing concepts. And John is an excellent interviewer, commentator, and human there to keep bringing it back down to earth. Thank you both for a truly enjoyable and educational experience.

If you like thinking about cosmic existence and being fascinated by the fact that anything exists at all, this podcast is for you. Intriguing, interesting, and mind-blowing.

Best Podcast Ever! Funny, witty, informative, thought provoking Please record another season!

I cannot believe my good luck of stumbling upon this podcast! John Green is my favorite author and I feel like he is the kind of dad or friend I always wished I had. He is curious and intelligent and kind. Along with the hard science presented by Dr Mack in such an understandable way, the podcast makes this material accessible in all its amazingness. And the human centered insights and observations of Mr. Green are helpful in making me feel included in the discussion. Love it! Highly recommend this podcast

This podcast was amazing! I like the Expert&EveryMan format John and Dr Mack are a great duo. Thank you so much! Can’t wait for something else like this from Complexly

This podcast was just perfect — basic, assuming no knowledge, yet substantial, deep, and thoughtful. And funny! I enjoyed every minute of it and learned mind-blowing stuff. Sad it’s over!

This podcast has expanded my mind and deepened my experience of being a human in this cosmos. Thank you both for your voices and work.

This podcast gave such a great in detail review of the universe in a very consumable way. Really love the philosophical elements of it as well!

I haven’t been moved like this by a podcast since first listening to This Is Love in 2018. Kudos and thanks to everyone involved in this production .

This pod was precisely catered to my interests so I have to give it 5 stars. Just like the universe, I did not want it to end!

Wow

While this podcast is definitely educational and has taught me a ton, I think where it really shines is in the juxtaposition of Dr Katie Mack’s and John Green’s perspectives. John’s earnest sentimentality and person-centered questions add so much value to Dr Mack’s carefully curated explanations of very complex evidence and theory. I came to learn, but I stayed for the conversations that made me feel stuff.

The dynamic between the two hosts is so enjoyable to listen to! Dr. Mack does an excellent job of presenting information in a way that feels digestible and has really wonderful anecdotes peppered in. Listening to John process Dr. Mack’s teachings (and reel from the magnitude of our universe and future) was so helpful in helping me feel grounded when I think I easily could have been filled with existential dread. I’ll be listening to this series over and over again, what a great job!

I have been enjoying the podcast, and each new episode can’t come soon enough. Each episode is enlightening, awe-inspiring, and humorous. The chemistry between John Green and Dr. Katie Mack is delightful.

Fantastic voyage from beginning to end of the universe. John is all of us, agape in wonder at the size, scope and majesty of our universe.

Excellent job, Dr Katie Mack and John Green.

I wasn’t so sure about this podcast at first. John Green’s statements about “this or that is making me nervous” seemed an unnecessary distraction. But as I’ve continued to listen I’m getting the picture, and seeing just how crafty John’s insertions are. Really grounds complex stuff for people like me who are just learning about it. I appreciate his concise and spot-on summaries of material. I even look forward to his life insurance ads in each episode. 😊 And Dr Mack is a wonder! I went out and got her book.

I just can’t stand the interviewer for some reason.

Come for the engaging, whitty, introspective discussion, stay for the policy genius commercials.

I love this podcast and look forward to every episode! Two of my favorite things: learning new things about the universe and John Green. Thank you for making this!!

I may be bias because this subject area is and always has been SO incredibly fascinating to me, but WOW! Everything about this series is perfection. I really appreciate Dr.Mack breaking it all down in a sort of “layman’s terminology” that I could follow and REALLY understand…in a way I’ve never been able to before. John’s commentary and questioning is perfection, as in, he represents what we all may feel and ask if we were to have the lucky chance to sit down with Katie and pick her brain. I’m so happy I came across this and I just want to express my gratitude to all involved in this podcast for stimulating and enriching my mind. I can honestly say that this podcast really changed my perspective and appreciation for the human race in a time where I have been increasingly feeling disgust and doubt. If I had to sum it up in just a few words, I would say this podcast is the epitome of intelligence, fascinatination and inspiration. Thank you for taking me on such a beautiful, thought-provoking journey 💕

one of the best educational podcasts i've heard (only one so not saying much....but.) every time i listen to the episodes i learn something new each time. i'm only a young teen, but because of this podcast, it's making me seriously consider doing this sort of collage/job when i get older. i never would have considered that, but this podcast helps me understand the universe in whole new ways that make so much sense to me. also you should totally get both green brothers on here for one of the episodes!!!!!

Loved the show. I am in awe about the depth of knowledge Dr Katy has about the subject. How she explains the most confusing things so simply is what brings me back to re-listen the show. And every time I pick up on something new! I love how every few minutes John summarizes what they have talked back. The universe is a baffling subject and in all the shows I have listened to before, I can tell this one is the best !!!

You can tell Dr. Katie Mack loves her work and is brilliant at breaking it down to be more accessible to people who don't have a ton of background knowledge in her field. I loved to hear her and John laugh, and also picked up on when they both were and are in awe with the universe. You can also tell Dr. Mack loves being an educator and I hope her students know how special it is to have someone who loves what they do teaching them. I keep coming back to relisten to episodes because I pick up something new each time. Also John does a decent job of providing summaries throughout the topic transitions for a good recap.

The topic sounds interesting but the Dr. explains complex topics with very few to no examples to help the listener understand. Also, she’ll go on long explanations and the male host will just respond with, “Okay. Interesting, interesting.” I also found the male host to be dull in his questioning and commentary. He’s supposed to represent the listener and yet he rarely has any questions or response other than to comment on how boring a name is of a scientific discovery, or to voice his existential dread. Not a good podcast.

I had just finished “Coming of Age in the Milky Way” recently, a book that tried to explain the beginning of the universe, the history of astronomy and physics particles that was on PBS many decades ago, which also won the Pulitzer. Then, an algorithm recommended this podcast. Perfect way to continue learning where we’re at now with what we know so far.

Katie Mack is fabulous but why does she need the “gee I’m too dumb to understand this” sidekick? I think even she gets annoyed with his act. She is terrific though and I find myself totally engrossed.

Is this guy John Green actually this anxious or is this an act?

makes me want to go back to school to study phyiscs

Hi my name is Pandora and I’m 12 years old and I LOVE astronomy and science so I discovered this podcast and I LOVE IT!!!! Thank you for making this podcast and expanding my mind, really thank you so much

This podcast brings together two of my favorite things: the enigmatic universe and John Greene’s commentary. From someone whose focus is usually literature and education, the way these two hosts collaborate to explain something that feels so incredibly dense is quite engaging. And, yes, I still had to listen to each episode twice, but it was worth it. Thank you. I am so grateful this is being made!

What a wonderful podcast, wherein John Green tries to find the fault in our… terms for concepts in astrophysics

John Green does a podcast with an amazing astrophysicist and it’s just as wonderful and humbling as everything the bastard turns his hands to.

And annoying format/presentation.

Turns out Dr. Katie Mack’s dumb is too smart to comprehend. John’s explanations help, but they are too brief. Consider changes to improve. I want to love this but current format isn’t working for me.

Feeling inconsequential? Listen to this podcast. Because you matter. And you are matter.

I love the dynamic on this podcast. Science is so much more interesting than what we learn in school!

So cool that I started down this space rabbit hole, big time, about a month ago. So cool this podcast just comes out!

I’ve always suspected that I’m an idiot, but thanks to this show I know it. I can’t even understand John’s liberal arts decoding sessions of what Dr Mack is talking about. Thanks for bursting my bubble. Great sound btw

This was a mix of inquiries and answers that was fun to follow and still brilliant. I’m very excited to listen to more.

Just imagine you’re listening to a podcast where a non-expert asks an expert deep questions. Now, imagine the non-expert is curious and intelligent and the expert can explain challenging concepts without resorting to jargon and excessive caveats. Congratulations, you’ve found that podcast! Enjoy your new found sense of amazement and wonder.

Wonderfully complicated and mind blowing subject presented in understandable format. Thank you! Can’t wait for the next episode.

Love it! So good!

Oh my goodness! Thank you, John for asking all the questions I’m too embarrassed to ask my astrophysicist friends. Can’t wait for more!

Katie Mack has always been a favorite person of interest in Nerdfighteria, and seeing her team up with John to discuss the deepest parts of astrophysics and cosmology while John adds a literary flavor to Katie’s excellent science communication prowess is really fun. This will be an incredible series!

I have new knowledge and appreciation of the cosmic microwave background after listening to Katie in this podcast. That is just one of the areas of learning. Very enjoyable podcast, I take my time with it and repeat sections as needed. If you like podcasts by Dr Paul Sutter or Daniel and Jorge, you will like this.

I’ve never been able to wrap my head around much to do with space and our beginning. This podcast is the first time I’ve truly understood some of these concepts. John and Dr. Mack have such a way with explaining, and I can’t wait to hear more!

I can tell already that this will be one of my favorite podcasts. Five stars for the content, wish I could give it six for the self-satisfaction in John’s voice as he seamlessly weaves a life insurance ad into the origins of the universe.
