I really appreciate when creators put podcasts on RU-vid and having the conversation on the screen versus just in closed captioning? So accessible!

@notlucadaniel Месяц назад

i like it too, it's really pretty! not having custom captions is not very accessible though to, for example, DeafBlind people (which can include anyone who has some form of limited hearing plus some form of limited sight) or people who need bigger text/text in particular colours for other reasons.

Having a curious, intelligent person who lacks subject matter expertise ask a subject matter specialist who has good communication skills interesting questions has got to be the recipe for a great podcast!

The ocean horizon analogy was a surprisingly simple way of getting my brain to finally understand the concept of an "equally far in all directions" universe

I love the illustration of John and Dr. Mac sitting in lawn chairs and looking up at the sky. Perfectly fits the vibe of the podcast!

@laurasmith-brese2729 Месяц назад

I actually thought of the 2 ppl as us the audience and then John and dr mack were the vibrating stars But yours makes more sense

@krakelakin7527 Месяц назад

As a physicist who's met Dr. Mack and admires her science communication work, and as a fan of John Green, listening to this podcast was kind of surreal! And a lot of fun to hear Dr. Mack parse John's excellent questions and give such clear, cohesive answers.

@BirdsOnPowerLines Месяц назад

I love this so much! Thank you! This is quality content. Dr. Mack's analogies combined with John Green's questions and narrated pauses to recap what we just learned is just pure gold.

@mrpearson1230 Месяц назад

Exactly! Please keep this same format. The lawn chairs looking into the night sky with cc is perfect! I knew most of this already from having read Neil Degrasse Tyson's books and following him on Startalk and Isaac Asimov panel discussions.

Yes! This is awesome, and I’m sure it’s intentional.

In which Dr. Mack re-iterates Hank's "Dude, no edge!"

@davetoms1 Месяц назад

John's realizations perfectly capture why science provides me with a deep spiritual peace, even as an atheist. The more I learn about this universe, the more I appreciate my relationship to it, my part in its story, and our inseparability. Where religion builds a relationship between an individual and an unknowable deity whose wants we can only guess at and whose existence requires faith, science demonstrates my relationship with my creator (the Big Bang, Stars, nuclear fusion, evolution, etc...) and provides evidence to support the narrative. Better yet, science humbly and willingly accepts change as we learn more. I feel connected to the Earth, to the stars in the night sky, and to the origin of all things, because I understand (to some degree) the processes that literally connect us. And so I feel connected to all things, in all places, throughout all of time. Science helps me feel at one with everything in a profoundly powerful, uplifting, breathtakingly beautiful, and deeply spiritual way. Thank you to both Dr. Katie Mack and John Green for sharing your conversation. I'm looking forward to more episodes.

@AnonymousFreakYT Месяц назад

I love the "ocean horizon" explanation for why the edge of the observable universe is the same distance away no matter where you are. It's the simplest accurate easy to understand explanation I've heard. There's more ocean out there, you just can't see it from where you are. You may be able to see that small island in the distance, and someone directly across from the island and a tiny bit to the side may be able to see that island (in opposite directions! To you it's North, to them it's South,) but you can't see each other, because you're past each other's horizons. (Flat Earthers need not apply.)

@levyv2948 Месяц назад

This is my favorite thing! I love astrophysics and the Anthropocene reviewed, so this combo is the best! Also Dr. Mack seems like an excellent teacher and I wish I could be one of her students!

@sccrespoc Месяц назад

I have missed John Green's advertisement hooks. Like we are just in awe about the universe and boom, get a life insure from policygenius. I mean. It's genius.

@ethansnyder2234 29 дней назад

Dude I love that not only is there a cool graphic with captioning put in the video and the little pulsing stars as you guys talk, but if you skip around, you'll see the that the stars are moving around the frame too over time, it's SO cool I think there's something also super charming about it being John doing this series, the non-sciency brother, it makes this feel less like a lecture (not bad, I love Hank too) and more like a philosophical, fun conversation between friends. I'm really enjoying this series

@abhig61 Месяц назад

Policygenius ads by John are so awesome. I love how John makes up a tagline.

@AnsonPavlov Месяц назад

Amazing design for this podcast. I love the side by side text with a little bit of star glow. It's so immersive and it really gives the audience something to engage with visually while an awesome conversation unfolds. Great job! :)

I couldn't tell you exactly what it is about two voices speaking to each other about a compelling topic while their words also appear as text on the screen, but I find it just so very pleasant and nice and enjoyable.

@buckysrevenge Месяц назад

I'm not sure what checkmark needs to be ticked to do it, but could you make this show up in RU-vid music too since it's meant to be a podcast? I know Scishow Tangents does this

Found it, just Google "Create a podcast in RU-vid Studio" and you should get where you need to go

@pootlovatowashere Месяц назад

Such a great concept for a pod! Thanks for making this info approachable and a little less daunting

@briannasears8155 Месяц назад

I got three minutes into this video and immediately knew it would become my favorite podcast series! I know nothing of astrophysics and have admittedly been a bit intimidated on where to start with learning about it (as it is a more Out-Of-Curiosity topic for me that I’m interested in exploring for fun). This is such an amazing dive into the topic and having John occasionally stop to clarify, coupled with the amazing analogies from Dr. Mack - I’m just so thrilled to be here and a part of this. I eagerly await the next episode! 🎉

@miniimaelstrom Месяц назад

I enjoy that in addition to all this wonderful information and the It's A Wonderful Life-ness of the two talking stars as character representations, the tiny stars in the background are moving, just like the real night sky. That was a delightful little find!

@opiethornton1479 Месяц назад

The illustration of Dr Mack and John looking up at the stars together on campung chairs is so gorgeous. I want it as a poster!!!! And as someone who previously reacted like John does when Hank talks about space in Dear Hank and John i really appreciate this podcast finally i understand something about space

@diananoss9931 29 дней назад

It hurts in the best way to listen to this podcast. Its second hand embarrassment kind of intensity of emotions. I needed to stop multiple times to breathe through my feelings about the universe. What a trip ❤

@ponyote Месяц назад

The mellifluous voice of John Green. I can't get enough of it.

@aalin5701 Месяц назад

There is something about that shell of fire around that holds everything we know, and beyond it is the things we can never see, that for whatever reason, makes me feel at awe and at piece at the same time. How things started still surrounds us, still forms the viewable edge of existence.

I truly love this. I'm a big humanities guy, and I've always struggled to conceptualize alot of these very ephemeral, hard to grasp and properly picture big scale scientific concepts, stories, and systems.

@kalliopephoenix- Месяц назад

As someone who has delved deep into space and Astrophysics in the last few years (including following Katie Mack's work), I didn't think I'd learn much more by listening to this, but I really did! I'm especially glad for this podcast because the interactions between the befuddled philosopher John Green and the amused Katie Mack hold endless entertainment value, but they offer great insight as well! Much like cosmic inflation did to the universe, I've been blown away by this first podcast, and I can't wait for the rest of it!

A beautiful start to a new series. This has expanded my knowledge of what I thought was the Big Bang so much that my mind is blown. I’ve always been fascinated with space, but could never find just the right source of information to truly learn about it, so this is exciting for me to finally have a series talking about exactly what I wanted to learn
