*******Next week's episode will be early***** Before I forget, I'm away at conference next week so Evacuating Earth on Jan 11 will probably get released around breakfast time (Eastern) rather than before lunch at 11 AM as is my norm. I'd imagine they'll be wifi in whichever room I'm stuck in but would rather get it out early than risk it.
I actually can't, the 'schedule' option treats the video as private, so I can't show it to anyone else in advance for review. Plus the scheduling options of our others platforms (soundcloud doesn't even have one, facebook, patreon, etc) don't match well. I won't be uploading though, just flicking the video from Unlisted to Public, it's already sitting there waiting for that.
ebigunso Makes sense, he probably has a few months worth already mostly complete and just going through the next batch. Ford's methods aren't just for cars after all.
now we will be colonizing a black hole and after that we can colonize the entirety of the omniverse edit: wait i mean't this as a joke but he actually did put colonizing a black hole XD
I swear Mr. Arthur: I always thought that I had a fertile imagination (in the best sense of the term) when it comes to space concepts , but your ideas so consistently impressive. You are a god among men!

Fourth state of matter Not gas, not liquid, not solid Forget that song (Plasma!) They got it wrong That thesis has been rendered invalid
I think Isaac is pretty young (late 30's), so I see this going on in say 2050, unless he has left for "Maws", to live there. But he still could do the show from there, and give us updates on all the projections he made, then all coming true, in real time, at that time!!
@@Arterexius Good thanks. One of the "coolest" things about Mars is the day length, about 25 hours, giving future colonists one more hour to put "important things" off, like work, so they can watch Isaac's videos : )
I've watched your videos for about a year and I am still amazed at how you manage to discuss these really out there and huge topics whilst avoiding the sensationalism that so many fall into. Thank you Isaac, I'm sure 2018 will be a great year!
Holy crap Isaac. I'm used to your videos being good, but I think this one is set well above your usual bar. And on a subject where I had little interest. Phenomenal work.
I must admit as both a aerospace engineer and a sci-fi addict I find your presentations fascinating. I now look forward to Thursday just to add to my knowledge base.I just wish the people who control budgets for development would watch your work and then they might understand why man has to expand into space. To be honest mankind cannot yet crawl and since people cannot understand projects that will take longer than the next election are important what chance have we of working on projects that could take many lifetimes.
Ferrous Bear I am not suggesting we start building Dyson swarms yet , even though to me they offer a credible way of adjusting the amount of infrared reaching the earth so we can avoid the worse effects of global climate change. I am thinking far simpler than that such as an ecological way to get to orbit , or even long term improvements to long distance rail networks so that more freight can be put back on the rail networks instead of the freeway systems. Generally the attitude is the problems are too big so let's ignore them , but should be the problems are big but we must fix them , so let's get going asap before they get worse.
@ Ferrous Bear No we have no need for the Dyson Swarm yet, but the environmental impact of metals mining on Earth can be mitigated by mining asteroids. The risks of launching material into orbit mitigated by space processing and refinement of above mentioned mined asteroids. The move from reliance on greenhouse gas and polluting fossil fuels by utilizing above mentioned space resources in-situ to create vast farms of solar power harvesting satellites would be a crucial benefit. And advancement of our species to a multi-planet or at least off-Earth species in case of catastrophic disaster on Earth, by developing colonies on the Moon, on Mars, in O-Neill Cylinder habitats around Venus, Mars, the asteroid belt or throughout the solar system and beyond is definitely something our species should be planning at this point. All these things we could invest in or budget toward now, or we could do nothing and allow the population to expand, the climate to heat up, costal regions to flood, rain forest carbon sinks to be destroyed, arable land to be overworked and polluted and dry up, horrendously costly (in lives and financially) wars for resources, refugee crisis' and the resultant resentment against the developed world, global terrorism; all of which the world's governments ARE budgeting for now.
With the current educational potential of the internet, existing industrial automation, and the space age developments coming into fruition very soon, we could have a post-scarcity civilization, were it not for the disastrously archaic political, financial, consumer and religious systems we have now. I have hope, but unfortunately not faith in the millennials, who have the least tolerance for the status quo to blindly adhere to this status quo, and yet are so preoccupied with the most vapid and self-indulgent of cultural distractions, to create a better system. I have hope, but I had hope in the 70s to when the world seemed to embrace (albeit bitterly) the post-war economic and social boom and the progressivism of feminism and racial equality of the 60s, yet look where we are now.
@Paul Walsh You could argue that there have always been 'vapid and self-indulgent cultural distractions', the difference is that those of us who are in our 30's or younger grew up in a world where it has been honed into an art-form with psychology. There are well-regarded books on how to exploit it for games in particular (as a hobbyist game-dev in my spare time, reading that was an eye opener, lemme tell you). There are quite a few of us who think long term. As for getting funding? Something I learned from my politician friends: Even at the city level, where all of them worked, nobody wanted to back a project that wouldn't have their name slapped on it. Anything that looks like it'll take jobs away is anathema to getting it past voters as well, which is how any opposition would word something like asteroid mining or an orbital ring. And that's not counting how many humans are violently opposed to a post-scarcity society because of it's economic implications.
@@DFX2KX Yes, if you can't offer the masses free stuff you can't control them. Having, and earning your own stuff sets you free from an economic dependence state, so to speak. So bring on "post-scarcity society".
8:28 finally i understand why oven temperatures are so high, but opening the oven doesn't burn us to death!! i've looked for explanations for months, maybe years. never expected to find the answer at isaac arthur's videos!!
Yeah, thermodynamics is not exactly intuitive for most folks. Issac is one of the few folks I've seen who can explain the basics to the layman in a way that makes any sense. I didn't get it either until my high school physics teacher gave a remarkably similar explanation. His other explanation was "If temperature was like the driving a car at a set speed, then deep space is an autobahn with nobody on it but two lunatics driving at 120 mph. Exciting if they crash, but they probably wont see each other. a pot of boiling water is like a demolition derby or a figure-8 race. a bit slower, but lots more accidents."
Flinchous, with respect, you may be confusing crazy with insanity. Crazy: well, we all know what that is (say from experiences with maybe one's last green-haired tatted up girl friend) but insanity, well that is very close to pure genius. Right?
Your last episode threw me into a state of existential crisis contemplating mortality and the eventual fizzling out and death of both each and every human and eventually the entire universe. It was utterly terrifying but enlightening. Thanks for your great series! Memento mori.
You should do more "well I'll show you" videos. Here's some food for thought; We'll never save the universe from entropy, we'll never be able to travel the multiverse, we'll never create actual personal universes like the microverse battery from Rick and Morty, and we'll never be able to create artificial gravity without centrifugal force. Show me, Isaac. Put me in my place.
Isaac Arthur Glad to hear I might've helped inspire yet another wave of genius from you. Whether or not that's the case, I love this channel and plan to start supporting it on patreon once I get a new job. Keep up the incredible work my friend.
Kip Jansson If Gravity has an associated particle I.e. The Graviton, that might lead to artificial gravity if we find a way to manipulate said particle, maybe. Notice quite a few "ifs" "mights" and "maybes"
Possible workarounds, If the universe expands and cools forever, the amount of entropy it contains goes to infinity. We can make entropy forever, though at ever slower rates. This means infinite subjective lifespan is possible for digital minds. In some physical theories, the vacuum can be in multiple states. Concentrating enough energy on a small enough volume can push it into a high energy false vacuum. This is the state that existed around the big bang, the false vacuum expanded very fast causing inflation. So our new pocket universe expands rapidly. The pocket universe may separate entirely from ours or stay connected by a wormhole. A several billion year delay before there is anywhere worth visiting may exist. Possible workaround for entropy as well. Diamagnetism can levitate frogs, turn it around to hold people down. Works if you have no steel implants.
Jason Foster That would be interesting. But my personal, though admittedly unobjective, opinion is that gravity is a property of matter's relationship with the fabric of spacetime itself, not necessarily a "thing" that can be controlled.
No other channel on youtube covers a topic so completely as your channel. I absolutely love it, the only channel I actually set aside time each week to watch.
Isaac Arthur, I have been lurking and enjoying your videos for some time now. First, thank you for the time you put in these videos. Second thank you for not getting over the top and trying to keep science and rationality in all the topics no matter how sensational the topic seems. I truly enjoy the sound of your voice narrating as your paint beautiful topics and daydreams in my mind. Finally, please keep up the fantastic work you are doing here. I look forward to many more videos to come and to rewatch many I have seen already. Sincerely, a true fan.
I genuinely feel your videos should be mandatory in schools. The more people we have excited as we are about science, the higher the likelihood of us making this a reality is. As always another awesome video
You could have just posted a video about how and why we'd endure the Sun's ridiculously inhospitable conditions, inspiring the science-fiction author or utopian futurist in each of us. But nooo, you had to also give a detailed yet comprehensible explanation of how lasers work, too, explaining a concept which many people have serious misconceptions about!
This channel is the best so far on all things scifi. Only problem is, I actually find his voice super relaxing, so if I watch vids while sleepy I might pass out 🙄 (don't worry, I always go back and re-watch lol)
agreed and agreed. my mind will sometimes wander into its own fantasy realm of Isaac's voice and my imagination. always makes for a great dream that night!
Alternate soundtracks for this episode should include; Island In The Sun - Weezer Walkin' On The Sun - Smash Mouth Walking On Sunshine - Katrina & The Waves Black Hole Sun - Soundgarden Share With Me The Sun - Portugal. The Man Hard Sun - Eddie Vedder
I have seriously considered jumping through the hoops to get permission to play black hole sun if I ever get around to doing an episode on that concept.
Wow, first reply from you! And that would make for a pretty good episode, not entirely sure how hard it would be to get rights to the song, though. (However, I think Chris Cornell would've enjoyed the pun.)
One of the nice things about Earth, I suddenly realise, is the ability to get up and walk outside. No need for any special technology, equipment or aparatus to help you survive... By golly, we have it good here.
I read Paul Birch's paper on colonizing the sun "Supra-Stellar Earth" in the early 2000's and was captivated - thanks for revisiting the concept Isaac!!!
Isaac, first of all wish you a happy and wonderful year. Secondly, I must again say that you're one of very few people who are able to provide me with hope for the future of humankind. I guess being impressed by the work of a genius does that to you ;)
Next thing you know, Finisterre lands on the ring around the Sun with bucket and shovel. "You never said that I had to land directly on the Sun, because the ring is still part of the Sun"
The Sun is a mass of incandescent gas A giant nuclear furnace We would not think to settle there For it would surely burn us Without the sun, without a doubt There'd be no you and me And now we all will learn How easy living there might be
Thank you so much Mr. (soon to be Dr. ....right?) Arthur, for helping to keep the dream alive! Your vids are inspiring and offer encouragement to many of us who have become cynical and pessimistic about humankind's future. Please keep up the excellent work! You are amazing, good sir!!!
Surely a Langston field would help with sailing a ship into a red giant..... Thanks for another Thursday keeping me entertained while dealing with shoes and Polish, the company is well appreciated.
:) Yeah it was much on my mind when writing that. I think we'll end up doing Mote for an Alien Civs episode some months down the road, already did one Niven Book of the Month and I don't want to do two by the same author in one year.
Isaac Arthur just finished Bowl of Heaven! The sequel Shipstar will be next. Basically built half a Dyson shell w a hole in the bottom turning it w help of giant mirrors into a giant stelazer & thruster pushing the entire thing through space using magnetic fields to keep everything stable. Next book should tell us why they built such a thing and where exactly they're going! Penned by Larry Niven and Gregory Benford. The why build anything this large the real question. What need were they fulfilling?
CuteFuzzyWeasel the sun is a mass of incandescent gas, a gigantic nuclear furnace where hydrogen is built into helium at a temperature of millions of degrees yo-ho it's hot the sun is not a place where we could live but here on earth there'd be no life without the light it gives
The sun is a mass of incandescent gas Without it there wouldn't be a place to live for you and me But the sun is really hot, a place to live, we think, it's not
Because the other two just quoted the song...the introduction is a reference to a They Might Be Giants song. He also left out the next line, since it wouldn't fit with the point of the introduction (or the channel in general-if you don't understand the importance of light to life on Earth, you probably need a few more years of school before you can understand these videos.)
I saw that Issac Arthur flag on Mercury. Is it your plan to become our space overlord? I guess I'd be cool with that. That was a really thought provoking video. Thank you!
Belmiris, I don't know about that, but, Issac Arthur can have a house or apartment in one of my towns on Mars, in the Venusian atmosphere and on my spacestead!
Definitely one of your more "out there" episodes, but really enjoyable! Two concerns that you seem to have glossed over: 1) Wouldn't a CME potentially wreck any structure close to the sun? What would be the statistical lifespan of a structure before getting hit by one? 2) You mention tethers between structure, but it seems like the tether passing through the sun's magnetic field would induce a massive current and basically fry it. Solutions?
Even in a CME, you are still talking about a particle count so low, it is a better vacuum than the best vacuum we can make here on Earth. So while there is a vast total energy, the energy density (the important thing for quick damage) is still extremely low. So a CME would do little harm to bulk materials. Electronics are a special case because of the subtle quantum effects they rely upon and the nano-scale precision involved. But there are alternatives to semiconductors as we know them, and some are extremely well-suited to space, such as Vacuum Channel FETs. (field effect transistors) which are essentially invulnerable to radiation damage.
It's interest watching some of these doom and gloom science shows now. Like the sun expanding and destroying the Earth. Well you can just do some starlifting, or you can use Shkadov thruster to move that problem star. Just go talk with Isaac, he'll sort you out :)
I still need the subtitles. I hope he does not discontinue them. Of course, I'd watch these even if there was literally no narration, but still subtitles. The value of these videos lies entirely in the fact that the words are chosen well. I am frequently impressed by how he consistently manages to present material in just the right manner where a scientifically literate adult doesn't have to struggle to keep up, but does have to stay constantly engaged to understand.
Evi1M4chine the intro is quoting a song, dude, holy crap. are you saying that lyrics are too referential for your tastes? if so, i think the human race might be a bit too social for you.
We could basically spend entire millenias around our own solar system before actually needing to go beyond...that's the more I learn the more I watch those videos. But I also now know that we will never stop growing, giving the chance. Thank you mister Arthur for nurturing my fate in mankind future glory in space.
I've been waiting for this episode. I wanted to see how this would work. Also, wanting to prove people wrong is one of the highest motivations a person can have. You're trying to expand people's perceptions of what reality is like.
As always man great job. Your videos always force me to think outside the box that I thought was possible. Even if I learned nothing else, purely the thought exercises alone are worth watching every minute. Thanks for what you do.
All your stuff is great, but this was exceptional! Thank you so much for bringing some of these ideas to my attention and imagination. I'll have to return the favor someday, somehow
As Scott Adams, of Dilbert fame once wrote: "Engineers take the word 'impossible' as a challenge. When an Engineer says something is impossible, that is code for 'I don't want to do it.' and the best way to get an Engineer motivated is to tell him/her that it's impossible and/or they don't have the skills to so it." And, here you go. You say it's impossible and only jokingly say you'll do it. But as soon as your volunteers echo back the same sentiment, you figure it out. LOL
I've been following you for a while now. I still remember your voice when I heard it first. Weird as hell but does puts me to sleep often now. Your channel has grown and deservingly so. I'm proud for some reason. Gives me hope.
You have made a few videos that I thought were going to be a little far fetched or dull but they have all blown my mind. Some fantastic brain food in this one.
The Sun being 998 out of every 1000 atoms in the solar system is a great way to describe the distribution of matter. Thanks to you and your team for another great episode.
THANK YOU Isaac for providing this awesome resource to learn about space, alien concepts and technologies, and more. I've been watching a few channels similar to yours and saw your Civilizations At The End Of Time series which was fantastic. Keep up the good work, and I can't wait to learn more in the future!
Just when I thought the limits of colonization have been reached Isaac goes further and colonizes the sun. Is there anything he cannot do? I look forward to more as always. :D
Yes, the movie Sunshine is one of my fav's as well. The Mercury transit bit was impressive for me, plus other portions as well. Very interesting video this week. The sun is fascinating.
yeah.. i just can't get enough of these vids. Breaks it down to everyday concepts so you don't need a degree to understand. Love your work Issac, keep it up.
Yeah it was literally the feather that broke the camel's back to make this epsiode, I was fence-sitting for a couple weeks when Steve explained the concept to me, I formally scheduled the episode one minute after we finished. :)
I'm guessing he means this is the channels 3rd birthday. If he means me it's a little over 9 months early, though it is on a Thursday this year :) Though technically the pilot episode was made in Septmeber, a few days before my birthday in fact, I just treat Dyson Dilemma as the real "episode 1"
*******Next week's episode will be early*****

Isaac Arthur Can you please do a video on different methods to get to space.
i remember a few episodes ago "we try to be realistic and down to earth here, also in a month or so we will talk about colonizing the sun"
Kuba Jackiewicz hahaha
+Kuba Jackiewicz -- And now you see, it was not empty words!
now we will be colonizing a black hole and after that we can colonize the entirety of the omniverse
edit: wait i mean't this as a joke but he actually did put colonizing a black hole XD
Not that crazy, just grab a potion of fire resistance.
There's nothing that makes it physically impossible, is their point I think

In some physical theories, the vacuum can be in multiple states. Concentrating enough energy on a small enough volume can push it into a high energy false vacuum. This is the state that existed around the big bang, the false vacuum expanded very fast causing inflation. So our new pocket universe expands rapidly. The pocket universe may separate entirely from ours or stay connected by a wormhole. A several billion year delay before there is anywhere worth visiting may exist. Possible workaround for entropy as well.
Diamagnetism can levitate frogs, turn it around to hold people down. Works if you have no steel implants.
Jason Foster That would be interesting. But my personal, though admittedly unobjective, opinion is that gravity is a property of matter's relationship with the fabric of spacetime itself, not necessarily a "thing" that can be controlled.
No other channel on youtube covers a topic so completely as your channel.
I absolutely love it, the only channel I actually set aside time each week to watch.
Isaac Arthur, I have been lurking and enjoying your videos for some time now. First, thank you for the time you put in these videos. Second thank you for not getting over the top and trying to keep science and rationality in all the topics no matter how sensational the topic seems. I truly enjoy the sound of your voice narrating as your paint beautiful topics and daydreams in my mind. Finally, please keep up the fantastic work you are doing here. I look forward to many more videos to come and to rewatch many I have seen already. Sincerely, a true fan.
Thanks! I'm glad you decided to break the lurking, particularly for such pleasant commentary :)
I genuinely feel your videos should be mandatory in schools. The more people we have excited as we are about science, the higher the likelihood of us making this a reality is. As always another awesome video
You could have just posted a video about how and why we'd endure the Sun's ridiculously inhospitable conditions, inspiring the science-fiction author or utopian futurist in each of us. But nooo, you had to also give a detailed yet comprehensible explanation of how lasers work, too, explaining a concept which many people have serious misconceptions about!
Meant in a sweet way! It's so enlightening. THANK YOU ARTHUR!
Timothy McLean what a crule crime
Honestly I feel like Lasers were cooler when I just assumed they worked via Magic.
Can't make em all happy. I enjoyed all of the info. This is obliviously a channel to learn from. So why watch and complain about learning LoL
FoodifyFlorida you do not understand sarcasm or humor, do you?
I've never been more exited for the evacuation of earth or the end of the universe you make amazing videos happy Arthur day.
There is this discovery channel evacuation earth episode, but I am sure Arthurs will be magnitudes better.
Yankees not allowed on peoples Republic of Sun - kim jong-fun
...been more (excited) for...
This channel is the best so far on all things scifi. Only problem is, I actually find his voice super relaxing, so if I watch vids while sleepy I might pass out 🙄 (don't worry, I always go back and re-watch lol)
agreed and agreed. my mind will sometimes wander into its own fantasy realm of Isaac's voice and my imagination. always makes for a great dream that night!
You can't live on the sun, it's too hot.
Isaac Arthur; "hold my beer"
What are you talking about Isaac? "Oh yeah! I'll show you" is my primary life motivation xDDD
I guess that's fair, but living in a state of relative safety I tend to forget that one ¯\_(ツ)_/¯
Alternate soundtracks for this episode should include;
Island In The Sun - Weezer
Walkin' On The Sun - Smash Mouth
Walking On Sunshine - Katrina & The Waves
Black Hole Sun - Soundgarden
Share With Me The Sun - Portugal. The Man
Hard Sun - Eddie Vedder
I have seriously considered jumping through the hoops to get permission to play black hole sun if I ever get around to doing an episode on that concept.
Wow, first reply from you! And that would make for a pretty good episode, not entirely sure how hard it would be to get rights to the song, though. (However, I think Chris Cornell would've enjoyed the pun.)
Hm... Zapan.
The Sunshine theme.
One of the nice things about Earth, I suddenly realise, is the ability to get up and walk outside. No need for any special technology, equipment or aparatus to help you survive... By golly, we have it good here.
I read Paul Birch's paper on colonizing the sun "Supra-Stellar Earth" in the early 2000's and was captivated - thanks for revisiting the concept Isaac!!!
Isaac, first of all wish you a happy and wonderful year. Secondly, I must again say that you're one of very few people who are able to provide me with hope for the future of humankind. I guess being impressed by the work of a genius does that to you ;)
happy new year sir can't wait to see what you have for this year
Absolutely amazing channel...thank you Isaac!
It's weird how i no longer think of colonising the sun as a impossible task.
Guess that's what Isaac Arthur does to you :)
Another brilliand episode of extraordinary series, provided as always by our beloved host, Isaac Arthur. Happy Arthursday everyone!
This video is so cool. I'm excited for the upcoming this you guys have planned for this year. Keep up the great work
"You can't land on the sun with a shovel and a bucket" I'll prove you wrong!
Finisterre "I regret nothing!"
Go at night 😜
Challenge accepted.
Next thing you know, Finisterre lands on the ring around the Sun with bucket and shovel. "You never said that I had to land directly on the Sun, because the ring is still part of the Sun"
Have you landed yet
The Sun is a mass of incandescent gas
A giant nuclear furnace
We would not think to settle there
For it would surely burn us
Without the sun, without a doubt
There'd be no you and me
And now we all will learn
How easy living there might be
James Burleson I’m glad I’m not the only one who heard it. :)

Dude. I swear you're a super genius. You should be working for NASA. Another great video. Thank you for all the information you provide us with.
Adûnâi ummm okay? I didn't come to the conclusion that he's a super genius based on this video alone.
He’ll make a great sci fi author
probably does
@@himikotoga1733 how's Deku?
I know Isaac. I think he would be frustrated by working at NASA. It is an old and ossified bureaucracy at this point.
Thank you so much Mr. (soon to be Dr. ....right?) Arthur, for helping to keep the dream alive! Your vids are inspiring and offer encouragement to many of us who have become cynical and pessimistic about humankind's future.
Please keep up the excellent work! You are amazing, good sir!!!
Soon to be Mr. ... for MASTER!
Surely a Langston field would help with sailing a ship into a red giant..... Thanks for another Thursday keeping me entertained while dealing with shoes and Polish, the company is well appreciated.
:) Yeah it was much on my mind when writing that. I think we'll end up doing Mote for an Alien Civs episode some months down the road, already did one Niven Book of the Month and I don't want to do two by the same author in one year.
Isaac Arthur just finished Bowl of Heaven! The sequel Shipstar will be next. Basically built half a Dyson shell w a hole in the bottom turning it w help of giant mirrors into a giant stelazer & thruster pushing the entire thing through space using magnetic fields to keep everything stable. Next book should tell us why they built such a thing and where exactly they're going! Penned by Larry Niven and Gregory Benford. The why build anything this large the real question. What need were they fulfilling?
0:16 "there would be no you or me, but its not a place that we could be" ! AHHH! you missed the perfect rhyming opportunity!
CuteFuzzyWeasel the sun is a mass of incandescent gas, a gigantic nuclear furnace
where hydrogen is built into helium at a temperature of millions of degrees
yo-ho it's hot the sun is not a place where we could live
but here on earth there'd be no life without the light it gives
The sun is a mass
of incandescent gas
Without it there wouldn't be
a place to live for you and me
But the sun is really hot,
a place to live, we think, it's not
Because the other two just quoted the song...the introduction is a reference to a They Might Be Giants song. He also left out the next line, since it wouldn't fit with the point of the introduction (or the channel in general-if you don't understand the importance of light to life on Earth, you probably need a few more years of school before you can understand these videos.)
I suspect Issac is single-handedly advancing the state of science fiction for a generation to come.
I saw that Issac Arthur flag on Mercury. Is it your plan to become our space overlord? I guess I'd be cool with that. That was a really thought provoking video. Thank you!
With him, it's Galactic Emperor or nothing! *HAIL ISAAC ARTHUR* ༼ つ ◕_◕ ༽つ
Belmiris, I don't know about that, but, Issac Arthur can have a house or apartment in one of my towns on Mars, in the Venusian atmosphere and on my spacestead!
Definitely one of your more "out there" episodes, but really enjoyable!
Two concerns that you seem to have glossed over:
1) Wouldn't a CME potentially wreck any structure close to the sun? What would be the statistical lifespan of a structure before getting hit by one?
2) You mention tethers between structure, but it seems like the tether passing through the sun's magnetic field would induce a massive current and basically fry it. Solutions?
To answer your first question: mere seconds barring any Clarketech.
1. Days to weeks
2. Free electricity
Even in a CME, you are still talking about a particle count so low, it is a better vacuum than the best vacuum we can make here on Earth. So while there is a vast total energy, the energy density (the important thing for quick damage) is still extremely low. So a CME would do little harm to bulk materials. Electronics are a special case because of the subtle quantum effects they rely upon and the nano-scale precision involved. But there are alternatives to semiconductors as we know them, and some are extremely well-suited to space, such as Vacuum Channel FETs. (field effect transistors) which are essentially invulnerable to radiation damage.
Amazing Episode. also it's very freaky how we'll eventfully extract matter from the Sun.
thank you Isaac.
It's interest watching some of these doom and gloom science shows now. Like the sun expanding and destroying the Earth. Well you can just do some starlifting, or you can use Shkadov thruster to move that problem star. Just go talk with Isaac, he'll sort you out :)
I don’t know if I’ve gotten use to your voice but I’d say your speech has gotten much better
evan448 lol was thinking the same thing, maybe the videos help him just as much as they help us 😎
Someone already noticed that and Isaac told them he's doing speech therapy.
well it definitely shows congrats to him
Yeah I stopped using subtitles a few months ago (I am not a native English speaker, btw).
I still need the subtitles. I hope he does not discontinue them. Of course, I'd watch these even if there was literally no narration, but still subtitles. The value of these videos lies entirely in the fact that the words are chosen well. I am frequently impressed by how he consistently manages to present material in just the right manner where a scientifically literate adult doesn't have to struggle to keep up, but does have to stay constantly engaged to understand.
Great way to start 2018! This was a very interesting and exciting video.
A++ THEY MIGHT BE GIANTS REFERENCE ISAAC, FIVE OUTTA FIVE
scrambo they actually corrected it to "a miasma of incandescent plasma" since the sun isn't actually made of gas. Still, 4.9999 outta 5
Evi1M4chine Memes have existed as long as communication has. Religion is the ultimate meme, for example.
Evi1M4chine the intro is quoting a song, dude, holy crap. are you saying that lyrics are too referential for your tastes? if so, i think the human race might be a bit too social for you.
Amazing as always Isaac and I'm seriously hyped for the next 2 weeks episodes, and have a great year
We could basically spend entire millenias around our own solar system before actually needing to go beyond...that's the more I learn the more I watch those videos. But I also now know that we will never stop growing, giving the chance. Thank you mister Arthur for nurturing my fate in mankind future glory in space.
Another video of the legend
Can't wait for the collab w/Dr. Paul Sutter.
_Release the Spaceman!_ ^_^
The opening lines were poetic. I kept waiting for a rhyme to resolve the tension.
They're from a song by They Might Be Giants.
So they are!
They Might Be Giants, "Why Does the Sun Shine?"
th-cam.com/video/3JdWlSF195Y/w-d-xo.html
Thanks for another great episode!
happy new year isaac!
Happy New Year!
Sweet! I've been waiting for this one for a while! Happy Arthursday everyone!
I've been waiting for this episode. I wanted to see how this would work. Also, wanting to prove people wrong is one of the highest motivations a person can have. You're trying to expand people's perceptions of what reality is like.
As always man great job. Your videos always force me to think outside the box that I thought was possible. Even if I learned nothing else, purely the thought exercises alone are worth watching every minute. Thanks for what you do.
Love the They Might Be Giants intro Isaac. Almost as much as I love this channel. Keep up the excellent work!
I love that they issued a retraction song, Why The Sun Really Shines (The sun is a miasma of incandescent plasma!)
All your stuff is great, but this was exceptional! Thank you so much for bringing some of these ideas to my attention and imagination. I'll have to return the favor someday, somehow
As Scott Adams, of Dilbert fame once wrote: "Engineers take the word 'impossible' as a challenge. When an Engineer says something is impossible, that is code for 'I don't want to do it.' and the best way to get an Engineer motivated is to tell him/her that it's impossible and/or they don't have the skills to so it."
And, here you go. You say it's impossible and only jokingly say you'll do it. But as soon as your volunteers echo back the same sentiment, you figure it out. LOL
Brandon Taitano p
I've been following you for a while now. I still remember your voice when I heard it first. Weird as hell but does puts me to sleep often now. Your channel has grown and deservingly so. I'm proud for some reason. Gives me hope.
You have made a few videos that I thought were going to be a little far fetched or dull but they have all blown my mind. Some fantastic brain food in this one.
Hey Isaac New video I see
Your an awesome creator so keep up the great videos
4 more years of Isaac
Do it at night
Am i right?
AlHoresmi Neil degrass Tyson
AOC I didn't know you were a fan of science!
The Sun being 998 out of every 1000 atoms in the solar system is a great way to describe the distribution of matter. Thanks to you and your team for another great episode.
They might be giants line got me so good
Your intro music is so damn inspiring and it gets me primed for the video. I love everything you do man, thanks for the great content.
Awesome !! I've been waiting for this since last Thursday! Here's to another fantastic year of Arthursdays! Cheers everyone.
THANK YOU Isaac for providing this awesome resource to learn about space, alien concepts and technologies, and more. I've been watching a few channels similar to yours and saw your Civilizations At The End Of Time series which was fantastic. Keep up the good work, and I can't wait to learn more in the future!
Amazing episode, I learned a lot of new things A++++++
Just when I thought the limits of colonization have been reached Isaac goes further and colonizes the sun. Is there anything he cannot do?
I look forward to more as always. :D
Lots of people talk about how "the sun is a deadly lazer," but Isaac Arthur actually wants to do something about it.
Yes, the movie Sunshine is one of my fav's as well. The Mercury transit bit was impressive for me, plus other portions as well. Very interesting video this week. The sun is fascinating.
fucking finally oh thankyou isaac i have been eagerly awaiting this episode, so my deepest thanks my friend.
That was your best intro yet. :)
The sun is the source of all life, just like Arthursday's are the source of all the amazing content
yeah.. i just can't get enough of these vids. Breaks it down to everyday concepts so you don't need a degree to understand. Love your work Issac, keep it up.
The solar laser just blew my mind. It is absolutely incredible. Thank you, Isaac. Your videos never cease to amaze me.
Yeah it was literally the feather that broke the camel's back to make this epsiode, I was fence-sitting for a couple weeks when Steve explained the concept to me, I formally scheduled the episode one minute after we finished. :)
That was a fantastic intro :)
It Was! His cadence almost had me expecting him busting into rhymes.
They're song lyrics by They Might Be Giants, for those out of the loop.
Awesome!
Perfect start to the year. This is definitely one of the best videos yet.
the title reminded of the phineas and ferb episode where doofinshmirtz met a guy who wanted to set fire to the sun XD
Mr Rishi The Cookie I know exactly what you're talking about 😂
This is such a treat. Thank you Arthur
Before all and of course... Thumbed up and shared!! Thank you Isaac!! Happy Birthday! (Channel's) Happy ARTHURSDAY everyone!!
Sgt. Shill happy birthday?? Did I miss something???
Jon Caser lol do you follow on Twitter?
I'm guessing he means this is the channels 3rd birthday. If he means me it's a little over 9 months early, though it is on a Thursday this year :) Though technically the pilot episode was made in Septmeber, a few days before my birthday in fact, I just treat Dyson Dilemma as the real "episode 1"
Isaac Arthur exactly!! Lol I probably should have been more clear on that.. My bad...
Sgt. Shill too late... I already ordered an enormous birthday cake and the biggest partyvan I could find.
I see what you did there in the beginning of the video and I love it.
I listened to that song again because of you.
This channel is awesome
heh, loved the TMBG reference in the beginning and the science through out, I do enjoy your content!
You can always colonize the sun. Just do it at night to catch the sun off guard.
I like your content, science seams to have forgotten how to dream and how to fight for it, glad to hear how deep you go.
Not sure if this idea has come up, but what about inward/downward bound: colonizing the deep ocean or colonizing and mining a rocky planet's core?
Yes, most likely, we've been debating the potential title for a while
Another to add to my favorites. Keep up the great work Isaac.
