Godier and Arthur on the same show for an hour. This episode is full of win.

Not gonna lie, i could listen to 5 more hours of this no problem.

2 of the best youtube channels.. ever !

Isaacs speech is near perfect now and its taken great effort on Isaacs part. Also great interplay between the both of you.

Isaac is great. Also, great to see a new science channel too. This is solidly produced.

two of the most important youtube science creators having a discussion for an hour, you're spoiling us John.

An hour long episode of Event Horizon with John Michael Godier and Isaac Arthur. *slowly takes off sunglasses* My god...

I liked he two-part collabs you've done before with Isaac, but this is freaking amazing. I'm formally requesting a 10-hour video series with you two. And on the topic of life extension, there's just so much to think about. I think one of the biggest things we're gonna discover in the next century is the actual nature of consciousness. I read somewhere a theory stating that consciousness is actually an emergent property of the quantum effects between atoms in the neuron's microtubules. Being just a humble physician I think I'm stuck at the cellular level in regards to experience, but thinking deeper than that is just fascinating. Life probably has a lot of properties that depend on subatomic interactions, instead of just molecules or proteins.

The second break. That was just awesome. Fusion, yes, yes, Fusion. LOL

I love Thursdays!

This channel discusses everything that rattles through my brain every day... only in an organized and eloquent way

Am I the only one who could listen to John and Isaac talk to each other all day? An hour isn't *nearly* enough.

John M, Godier and Isaac Arthur,... What an Awesome Collaboration, Two of KZfaq's Top Sci-Fi Authors,... Cheers, Guys.

What could be better my 2 favorite you tubers in one place.

Anna- "Isaac, join me, and together, we can rule the galaxy" :P

John and Iasic? What a great thursday!

I discovered JMG's channel after Isaac's and separately (meaning independently of their collaborations.) The more of both these guys I hear the more I like. I really love the collaborations with you two as well as Joe Scott, Frasier Cain, Curious Droid et al. I hate to sound like a star-struck sycophant but you guys utterly rock. I always look forward to your new videos and even find myself re-watching your videos repeatedly. Thank you guys for the quality work you do.

Damn. Shivers go through my body at each episode! Love your long format!

This is fucking incredible. You both are some of my favorite creators and this longform discussion is so endearing. I can't imagine editing all this, too. Great job from everyone involved.

I just can't get enough of this stuff. The really unique thing about these two channels, IMHO, is a combination of making old content fresh and making videos on those abstract ideas that people just don't cover. They give us just about every aspect of say, AI or Arcologies. And then there is the really unique stuff. Dumb Aliens? Well hell, why not? Cyclic Apocalypse?! Digital Death? I could list 20 more examples. And nearly every single upload on both of these channels is quality stuff that I just devour. We don't just get a 7 minute clip with a talking head and a bullet list. Newp. We get music, awesome freaking backgrounds, insanely in-depth analysis, explanations, etc. These guys seriously deserve their own TV show as well. Thanks guys, really. These are more than just some YT clip to fill the silence.

With Dyson Spheres I feel like we're hoping to see clunky bits of metal sturctures in space...like how a Hunter-gatherer may imagine aeroplanes would be made out of wood...If Dyson Spheres etc exist they are probably more akin to blackholes..If you think about it all blackholes do is absorb energy/light, and they seem to be at places in space where most energy is found. I am totally copyrighting this idea!

Thanks to John and team for producing this highly thought provoking episode! It got me thinking about how the scattered human diaspora may interact with one another at the edge of the heat death. It would obviously be advantageous to a civilisation to bring under its control as much matter as possible, so that it may use it to light fires deep into the darkest night in order to keep the gears turning. Perhaps, as the human diaspora inexorably diverges in terms of their culture and identity, we will see intense resource wars raging at the end of time, each civilisation hoping to lay claim to a little wax to keep the candle burning a little longer.

Mr. Godier, you must upload MORE!

I was so excited to see this uploaded and waited until some time after I watched Isaac's newest video. Watched this while washing dishes last night and was smiling the whole time. Absolutely loved it. I look forward to Part 2 eagerly. :D

This is amazing!! I've been waiting for this for two years. Oh god my heart

I've been binge-watching all of the episodes. Have a lot to catch up to! Great content as always. I'm never disappointed here.

Having both of you on a single podcast was bliss! You should do it again for like 6 hours.

The thing that makes me wonder about giving "filter" status to the jump to Eukaryotes, though, is that it didn't happen just once in the time period in question. Around the same time (give or take a few hundred million years), Eukaryotes also absorbed some of the cyanobacteria ancestors of modern day chloroplasts, integrating them into their life cycle. Mitochondria and Chloroplasts might not have been the only ones, either.

Great video and another great interview John. I look forward to Event Horizon every week now. Who needs the Science channel when you have Event Horizon. You rock John!

I stumbled upon and subscribed to each of your channels independently. It’s so exciting that the two of you are collaborating! Thank you for all that you do to make these amazing shows happen! Respect!

Been waiting for this interview .Thanks event horizon.Two of my favorite channels.

I'm giving this one a thumbs up even before I watch it!

Wonderful and thought provoking conversation between you and Isaac Arthur! I loved every second of it :D

This is the best episode so far! I love the content that both of you create! Please keep going.

The thing I love about about both these great channels is the fact I won't see too far into the future maybe if lucky another 35 years and it gives me glimpses and insight into the possible future for earth humanity and the universe , so thank you both very much

A lot of information with smooth presentation. One of the best. Thanks David

A fascinating conversation, thankyou gentlemen. Im loving the long format and it was great to hear Isaac speak in a conversational tone. Keep these coming John!

My two favorite KZfaqrs in one video! What a glorious day

Isaac Arthur!!!

Awesome video! These topics are like a can opener for the mind. Thanks for all the hard work you guys put into these entertaining vids. 🏆👏

John and Isaac together again. Please do more collaborations as we can never have enough.

The most enjoyable conversation I've heard yet. My favorite two thinkers. Thank you both, you make me think and expand my thoughts.

Delightful chat! You're both awesome. Bonus points for the best channel plug I've heard in a long time.

Instant like

I love Isaacs accent !! I'm English , but familiar with American T/V , Film , etc . And I have never heard an accent remotely like Isaacs !!

You and Isaac and amazing when talking together next episode should be you two and Dr. Zubrin

41:50 When does the "Baskin Robins Galaxy" Episode come out, and will it include expanded discussion of the Quantum Cheeseburger?

When I first discovered you I couldn't listen to more than a few minutes due to the impediment. I can hear that you're really working at it and it's getting better. BIG PROPS TO YOU. Some parts are still hard to understand but I can now listen to the end. I love being able to listen now. Thank you

2 of my favourite youtubers i could listen to you guys chat every week

I love Both of These channels

These two are awesome by themselves. Listening to them conversate with one another is very cool to listen to. The ideas they have are just amazing and I think they should make a channel that consists of them talking to eachother because they are just so damn fun to listen to for so many reasons.

My 2 fav channels. Thx a ton JMG and Isaac

Indeed, fusion is very powerful. *wink*

I hope you'll do another episode with Isaac Arthur. Very interesting to hear the two of you talk about the future for mankind.

John, can you please have a discussion like this with Isaac Arthur again? Whatever the subject, I wanna listen to you two discuss things again! Isaac has more in his brain the most people. You have the ability to ask the right questions and understand science on a level very few journalists could ever reach! I am enjoying Event Horizon more and more now. But it took time to get used too, since most sciencetists cant discuss a subject like you two can. You are gfreakin fantastic in guiding the sciencetists who gets off track and ask the right questions to them, even if they might not think its important. Consider it? Please?

I thoroughly enjoyed this video. Second time watching it. Gives me continued inspiration and motivation to keep myself healthy and strong for as long as possible, with the intention of intercepting sufficient life extension technology so as to be able to experience as much of the future as possible.

I love listening to these 2 talk. They both know what the other is about and they talk in the same language (not just English, but the same lingo).

Wow Mr G. I found your other channel a couple months ago & really enjoyed your short format to the point that I wasn’t at all sure I would like this longer podcast type of show. Well now I am hooked. Thanks for all your ideas to stimulate our own thoughts. Clark and Isaac are certainly great authors but I have never found an author I enjoyed more than Heinlien. Just my two cents. Looking forward to your next offering.

First time ever listening to both John Micheal Godier & Isaac Authur...These guys have some very cool, original and thought provoking ideas. Won't be too long before both these guys are collaborating with some great film directors, putting their amazing imaginations to work for us all. If they can imagine it? We can build it!!! Real pi** off none of us get to see how things turn out : )

Great! Exciting partnership! thank you, guys!

Love and watch you both continuously glad you came together for this I am legit giddy

suggestion for a future collaboration: what do the 2 of you see as the first several steps from now to real use of the inner solar system (asteroid field inward). by use I mean mining, colonies, tourism, energy collection and food production for use on earth and similar activities. like both of your channels and love the collaborations.

Oh, this is going to be good...

Isaac Arthur needs to go on the Joe Rogan Experience, Joe would would have his mind truly blown, Isaac is the most articulate scientific commentator and futurist I've heard, he would set a new standard on that show.

I just found this total gem. Everything i love to think about. Thanks!!!!

Made me incredibly happy to see Isaac on this channel!

That hour seemed to fly by at the speed of light. More and longer please!

Im glad U 2 collaborate to bring us great content!

You don't realise it John but you are actually doing humanity a great service by highlighting possibilities of the future.

My two favorite futurists, I love it when you guys do a thing together.

Wow I can barely recognize Isaacs voice now. I used to listen to his old stuff and became very used to his speech. This sounds like a totally different Isaac.

Everyone who loves this channel and John Michael Godiers solo (I like those a lot too), support him on Patrion IF YOU CAN! He isnt doing this for the money, but with funds he can "do more". And deliver even more to us. Also, nothing proves how much people enjoys his work like when people actually tributing a symbolic sum! Even if its 1 Euro, it is something people only do when we really like something. Oh, Isaac Arthur is starting to earn a bit from his channel, by getting forced too lol. But he can now put money into it and have a large crew helping. Just imagine what John Michael Goodier could do with this channel, if it paid him more then his work? SURE, he would still be out in the garden fighing for his life vs the army of weeds! But still....he does this on his free time.......imagine if he had all day?

So much more insightful and informative than the Sutter videos which typically devolve into "IS IT ALIENS? We don't know. I AM A PHYSICIST." "DID I MENTION HOW LITTLE WE KNOW ABOUT THE UNIVERSE" "Eisenstein is just a historical footnote."

My two favorite scientists!

These two channels ( it is definitely group work for both of those channels) saved me from depression. Thx Everyone involve in these channels 🌙

Love this video!! the AI trying to get Isaac to stage a coup! that was great!! really enjoy both of your work! thanks

i have had YT serve this up at least a dozen times and yet i still chuckle when i hear Anna approach IA with ..The Offer.

What I wouldn't give to be able to have a 3 way conversation with you guys... One can always dream.

This was so brilliant!

John and Isaac are the best. Thank you guys.

Another pertinent question to life extension is not only will it be possible to greatly extend lifespans during our own lifetimes, but also will it be accessible to everyone, or even most people? I can only imagine the social unrest tagging along with the idea that only some people get to "live forever."

Starmaker! Wish people talked more about that novel. Also kudos to using Stellardrone as background music :D Great topic, and great interview.

So good. Watched. Re watched again later.

I think with the knowledge that you bring to all of us about the space and the universe we cannot be ignorance anymore by choice thank you very much for your information

👍🐣from Montreal,Canada. Your channel is excellent for learning ! Bravo

I thoroughly enjoyed this and am returning to watch again

Here’s to another 100,000 years of JMG videos.

Keep doing what you guys do. The world needs more people like you guys. Thinking about the future in the terms you do is not that common I dont think. Good work guys! :)

Rare Earth ----> Multicellular life --> Complex animals ---> Animals with a chance to be intelligent ---> Intelligent animals that create technology. These filters are probably responsible for 98-99% of the Fermi paradox. Remember, humanity in it's current form has existed for 300.000 years at least. 290.000 years of those we were hunting on the plains before we bothered with agriculture and writing. What we call modern science started about 300 years ago at best. We've been able to ask these questions and start looking for answers only in the last 50 years. Even the smallest delay in development could mean that two nearby civilizations completely miss each other. The same way we plateaued as hunter gatherers for hundreds of thousands of years, we are always just one world war and / or climate catastrophe away from plateauing at a generally lower level of technology that is available for us today. We could nuke and global warm ourselves to a point where 3000 years from now we cannot defend ourselves against an asteroid that wiped all life forms out that are bigger than rats.

Interesting topics and a calm beautiful voice. Thanx again for your work isaac Arthur. :)

Issac often says that even if most people/civilisations would decide to not expand there would still likely be some that would. When listening about how civilisations would diversify after leaving the solar system I wondered if the same doesn't apply in reverse. With countless habitats floating in space if people in one of them decide to leave there is a possibility that a few other will not allow it. After all there is not much material benefit from other "countries" colonising the galaxy, while it creates great risk that one of countless colonies will turn hostile. With a Dyson swarm it's easy to imagine that some would want to expand, but it's entirely possible that some others would not allow it. You may actually need majority of people wanting to colonise, and even then the few remaining could do what they can to prevent it.

That was an amazing video, I love you guys!!!

50:25 I've wanted a story based off of this concept for so long

the fermi paradox is my favourite paradox

Great episode! Thanks to you and Isaac.

Awesome guys :D loved it!

43:00 Isaac, if you haven't already, read the Bobiverse books. It's a great trilogy about a von neumann probe and I think you'd love it.

Event Horizon and SFIA are basically the only channels I follow

Freaking incredible conversation! Loved it!
