These remind me of the speculative essay collections by Asimov I read as a teenager. Science, math, imagination and the promise of adventure.
I am absolutely amazed by you. You're one of the most important people, and channels, TH-cam has ever known. Don't ever let go of this basic inspirational style. I'd even go so far as to say that you're the Carl Sagan of our time. You deserve the world's attention... not just a few thousand people on TH-cam.
Wow, Sagan, that is very high praise indeed Justin, my thanks!
I concur 100%. Simply brilliant
I would not go as far as to call IA the new-gen equivalent of Sagan ; but a worthy successor to the legacy of futurism and optimistic science indeed.
Yesterday I had a friend round to my house and played the first Isaac video that came up on my home page. This was at around 4pm. I dropped him off at his home and he asked me to remind him of the video title so he knew what to search. At 3am (U.K time) I got a text message to tell me he's still watching Isaac Arthur videos.
@@shakovhudds4213…
I can relate…
When I first found this channel, after the first few videos given up by the algorithm, I thought “wow, this guy makes some interesting videos… I’ll probably watch them all.”
Two days later, I was like, “How many ‘🤬ing’ videos does this guy have?”
And that was a couple/few years ago.
Your Starship Unity narrative is my favorite. I especially loved the part where the science officer takes 20 min to get to the point ☺️ makes me smile every time.
I hope you can make more narratives. When you add story like this, it really pulls me in.
I wish most or all space documentaries were this thorough and entertaining! I love your videos!
Holy shit. You make it look so simple, to slowly colonize our Galaxy, gradually making mankind less likely to go extinct with each new world...
And by the end of this video, I was thinking: the Unity by itself could do a lot of the job, but can you imagine if the success of Aurora make Earth build an entire fleet of garden ships, sending them in all corners of the Milky Way? Suddenly, the whole star cluster would be populated by humans in less than a millennia...
A lot of stuff in space just gets named really literally, so I guess "cluster" must get used a lot.
Make 1 ship. The next colony makes another, and another, and you have hundreds pretty soon.
Every stop along the path, is like a fork in the road at which you choose both paths.
Am i the only one who thinks that Isaac should right a book?
The incorporation of Fact and Fiction, blended with a delivery system to surmount any learning curve is astounding.
Keep up the great work man. Looking forward to your next video!
Yeah, I think you're right. He would make a good popular-science author.
I've been watching your channel for 2 days straight, this is amazing! Your channel is soooo under subscribed.
Thank you, and welcome to the channel!
rookie numbers son
don't fucking stop man. you are amazing. absolutely amazing.
Honestly, why would someone dislike this vid? It's awesome
Yeah, notice how it's just one sad sad soul that did that?
Mr Busy yeah unfortunately 😆
Its the guys lisp or some speech impediment that's annoying.
I'm impressed you got through all three episodes then, I suspect about half the new viewers find it annoying and jump out in the first minute or two, never to return.
Isaac Arthur that's a shame. I thoroughly enjoy the videos and I personally believe that your 'speech impediment' is minuscule to non existent. I make daily vlogs and it isn't always easy; you make videos about incredibly deep subjects and they're easy to understand with the way you describe and explain them. No mental impediment! 😆👊🏻keep it up Isaac.
I am devolving my own sci-fi universe and this video influenced it a lot.
Future Anarcho Capitalist
@@TheSkullConfernece what
They need to hurry up and make all the tech breakthroughs to do this. I want up there!
The whole "immortality" thing is top of my list. :p
You could actually do. Just need a healthy body and a crap ton of money to live up to life extension and then to be able to afford it.
The whole point of this channel is that tech breakthroughs are not necessary! We could make 98% of what's talked about right now! It would be nice to have stronger stuff to tether a space elevator, but we could do it with stuff we have. The only thing missing is political and economic will.
Ian maybe not a space elevator, but definitely an orbital ring, which is even better
Mr Arthur knows so much because he is an alien that's done it all before or he dose a lot of research, I haven't figured out which yet.
Man, this si definitely the best channel, Well back to my pod to be frozen another week.
More of this. MOAR. The slice of life stuff is what really carries my imagination.
27:00 "As long as we have each other, we'll never run out of problems." Keeps life interesting at least.
I used to read a lot of sci-fi, but I've hardly read any since discovering SFIA. Turns out, what I enjoyed about sci-fi was hard speculative futurism, and Isaac gives me enough to completely occupy my imagination.
When can we expect a book from you, Thank you for your amazing work
Hell yes, I would buy a copy for sure!
First he would need fusion power for the habitat in which to grow the trees from which we could produce the appropriately futuristic paper for such a book.
I'll second that.
Me seven!
Another great video. Thanks. Good to see the Captain was promoted from Hyperion to Unity :)
You've got to be one of the smartest people in the world today!!!! Not only are you seriously intelligent, but you keep churning out a TV quality product week after week.
I sincerely hope that you're making a fortune of of these videos. Because, god knows that you sure as hell deserve it!
Once again, bravo!!!!
"This is the Void Sailing Ship [V.S.S] Unity. A proud ship with a history of 100,000 years settling the galaxy. As this broadcast reaches you, we are taking the first steps in setting up the first ever intergalactic colony. It will take a long time for us to reach the other side, and longer still for you to receive word of our success. Remember the moment Humanity became Intergalactic."
-Original Captain of the Original Unity upon departure from our Galaxy. (Or at least I imagine it'd be something like that.
I love how you mentioned my all time favorite game [Alpha Centauri]
I think it is worth mentioning that the ability to build a space elevator around a body depends heavily on the body's rotation rate. The specific strength requirements of the construction material skyrocket (so to speak) for massive, tidally locked bodies, so space elevators are not guaranteed. (P.S. I love your videos and watch your channel religiously. Keep it up.)
Yet another reason to use orbital rings instead.
You have a very good point. The space elevator idea would never work. Gravity of the planet would bring it down.
I think there is a slight megastructure fetish tendency on this channel. Gravity schmavity, if building a structurally sound, load-bearing elevator isn't practical (in the sense of not being 'worth' the effort to build and maintain), Lofstrom loops are good solutions for worlds with an atmosphere, and EM Railguns are good solutions for worlds with little to no atmosphere. Braking fuel or ablative mass is inconsequential next to the fuel mass required for ascent from a high-G (0.8G and up) gravity well.
And both are much less time- , material-, and labor-intensive than an Orbital Ring; with reference to the video subject, colonization, an Orbital ring may well get built, but probably long after the colony ship has been either converted into an orbital station or has refurbished, refueled, and moved on to its next destination.
@@HuntingTarg
What I don't get..
Why do everyone always talk about a continuous Rail Gun..
A long tube.. Yes.
But the Electromagnetic bits can be separated by streaches that suck gas out before it and repressure in the wake.
Or heck, just connecting rods.
These EM don't throw it enough to get to space. Just enough to get to the next.
With the last giving it the last excellaretion.
This way both humans can survive it..
And the costs of fuel and maintenance are less.
I never thought possible falling in love again, isn't science beautiful?
22 people stayed on Earth :P
I can not understand how someone can dislike such a great video.
Thanks to Arthur for fueling the imagination of something that can be our future.
You are such a smart and amazing person I love these videos dude!!!!!
Thanks!
Is it weird that my mind has turned all of this into a BSG-style Sci-Fi drama? The episode where they tear out the outcroppings to make the space elevator is particularly surprising!
I wonder if a gardener ship might eventually stop bothering to intentionally seed colonies, and just cruise between systems forever, refueling as needed. Or if they might build more ships, and travel around as a colony fleet, rather than a single ship. The fleet would probably fragment as various groups split off to do their own thing, which might provide even more interesting scenarios as ships might stumble upon previously seeded colonies, by a different part of the fleet. Interesting things to consider.
In a trillion years if we are still here, the observable universe will have grown larger because of us. That's amazing.
Great series Isaac! One point to make - at around 19m mark you talk about atmospheric pressure constraints. The range of human habitation is about 0.47->9.0 ATM. Too low and people are prone to embolism. Too high and sinus cavities, etc will collapse. I'm sure that specialized suits and gene-eng can adjust that range, but there are still limits there too.
I have essentially the same early colonization economics pictured for my story at Zeta Tucanae, except that precursor robotics get most of that setup before the heavier colony ships arrive.
Great work!
I subscribed. Your videos are awesome!
29k subscribers and couting! 30k soon! Good Job Arthur!
Andy Popescu almost 600k now I’ve never been so proud of a TH-camr before
You should do a shout out for Arthur on your channel
@@patriot1724 I did. He was an inspiration for me
@@AndyPopescu
Cool thx man plus for this comment being from 3 years ago you have a lot of dedication keep it up man
Great episode!
I just want to say that you are doing a FANTASTIC job and i mean it. Channels like this is what humanity and especially the youth needs right now. We had an impromptu speech for our speaking class visa marks and i talked about the Kardashev scale ; a lot of people were surprised about what you can do with just %1 the speed of light and some 3d printers.
And even tough i knew a thing or two about all of your topics on this channel , you go in depth and that is what helped me give a speech almost as long as one of your videos.
Keep up the good work!
It's very exciting hearing someone put this all togeather into a few videos based on potentially feasible methods of colonising other solar systems. I wish humanity in whole would focus of this a lot more and put it into the publics and get everyone working on it. We need to expand away from Earth before its too late...
Sid Meier's Alpha Centauri is a Masterpiece, period.
I seriously wait (rather impatiently) for each new video now. Fantastic!
Nice touch with John Glenn on the voting ballot.
Thanks
Another great video from Isaac Arthurmov!
Amazing content. Thank you so much.
Congratulations on your wedding Issac, I've thoroughly enjoyed your service! Thanks a million )
Speaker For the Dead is an incredible book. One of my all time favorites.
This kinda reminded me of a book I read a bit back Building Harlequin's Moon by Larry Niven and Brenda Cooper. It really made me wonder about what kind of right colonists would really have in this or any other similar situation.
Your realistic view throws most of sci fi out the window but I can imagine maybe political upheaval by new generations born into an isolated world but still with knowledge of greater humanity.
Continue this series. It can be so much more than a trilogy and you make the most amazing videos. Consider how civilization would develop on a planet tidally locked to its star, or a lava planet, or a planet with a corrosive atmosphere. So many possibilities.
"We get a message they arrived safely, 50, 000 years after they sent it and half a million years after they left." God, imagine we got just that message tomorrow! How confused would we be, with literally nothing we could do about it?
I hope the singularity will happen in my lifetime so I can experience this stuff in my lifetime..and well.. live forever pretty much
_Speaker for the Dead_ is a great book. It does, however, feature a civilization that has created the ansible, a device that enables instantaneous communication between worlds.
Great Video with lots of food for thought.
they would also invent new tech onboard the ship also, after all they would have new needs for various problems.
26:29 "It is entirely possible that the ship Unity would barely have left the system before the colony's unity begins to depart too." Great turn of phrase!
This story was very engaging and stimulates the imagination. There are a couple of issues that were glossed over: (1: Does Aurora already have some sort of life on its surface? (The existence of O2 in the atmosphere suggests this.) If so, how extensive is the colonists' task going to be at assessing whether there are any disease organisms naturally occurring on the planet. In a scenario like the one mentioned here, the possibility of threats to the health of the colonists would be paramount. (2: I think it would be more likely that robot ships would arrive well ahead of Unity and begin the work of assessing the Tau Ceti star system's resources and to also begin building basic space infrastructure before any colonists actually arrived. I wouldn't be surprised if power satellites, orbital spaceports with space elevator tethers, skyhooks and even orbital rings would either already be built and waiting or under construction before Unity arrived. And if these robots were so programmed, they would probably set up laser propulsion stations with power so that lasers could be used to slow Unity down as it approached. All of this could probably be done by mining materials from tiny asteroids.
The first what we should do in other solar system is...build Space habitat.
Energy from unrenewable source is expensive, but fusion and solars are cheap.
Also unlimited XD
I'd love to read a sci fi book exploring your ideas
This and your fusion videos are my favorite. They're all fantastic, but those two are exceptional. Thank you for your videos.
I'm glad you mentioned the Mars Trilogy. Read it multiple times in HS and watching the terraforming video was basically just a refresher on the ethical dilemmas in that book. Also I vaguely recall those locations of the ideological camps you mentioned in the video to be the same in the books.
Nicely considered and presented.
I read John Glenn's memoir; a bit of a rose-colored self-portrayal, but still a phenomenally adventurous and fantastic life.
He did the most remarkable thing; one time as a publicity event he appeared on national and international TV with Yuri Gagarin some time after their respective historic flights - and after the cameras had rolled and he had escorted him on a (curtailed and limited) tour of some of NASA's facilities - he invited Yuri to dinner at his home, with his Soviet comrade 'escorts' waiting outside the front door.
@Issac Arthur
Kim Stanley Robinson's novels are my favorite from that list, although I liked most two of his books in particular; one about the journey to Tau Ceti (which, I think, portrayed the mission as a semi-disaster, if I remember it well), the second about the monorail city on Mercury (which was a conceptually fantastic read).
I particularly like the amoeba variation of the gardener ship - doubling itself at every stop. If it's a Methuseleh / sleeper ship and therefore necessarily has relatively mature molecular nano-technology (MNT) then the crew also presumably has the option of doubling themselves too. In an adult cloning (more like MNT copying) with memories intact kind of way.
I agree with Dan all your videos are awesome
Awesome video mr. Arthur! A wonderful blend of science fiction, fantasy and futurism. NASA's planned return to the moon is getting hung up on lunar spacesuits costing an estimated half billion dollars each! Hard to start a colony if 12 people gotta share one suit!
I love all those videos, I have speech impedidement as a result of a few strokes and I find you an inpiration and now that you are casting with Fraser, I'm in heaven now, keep up the good work! TY VM
Thanks John!
Best video yet ... Well done Isaac
I really love how you sneak in information about how much the colonists go to the bathroom 😂. How much Champagne they drink, how mysteriously they gain soil for hydroponics at the same rate of food consumption 😁.
Actually, by the time we reach this level our communications will be using a wave-particle duality form of quantum entanglement allowing for instant communication regardless of distance.
This, of course, changes everything you can maybe just make some revisions but I don't see that working and I know how much you enjoy doing this so yeah let's start over again.
Hitchhiker's guide to the galaxy ark `B'
Every colony needs its Telephone Sanitizers :D
That's one thing we have covered thanks to Douglas!
One thing that's been bugging me about that bit of H2G2 lately is why you'd have sanitising telephones as a profession, rather than just building a sanitising mechanism into the phones themselves.
Doubly so if you have the technology to launch an ark, as getting that built and launched pretty-much goes hand-in-hand with having good-enough automation to get rid of the jobs for the people on the 'B' Ark. Though that would also apply to most of the jobs on the other arks, too.
Roxor128 So the human psyche that has evolved to set goals and fulfill tasks doesn't go insane when there's nothing to do?
I think you're analyzing a little too hard. That series also has a spaceship that uses the power of bistro math to travel faster than the speed of light. It also is a series where you can fly if you get distracted at the right moment while falling, since you would throw yourself at the ground and miss.
everytime I see a new Isaac Arthur video, I just hit the Like button immediately, because I know I will love it.
wow. this is one of your best videos to date. I love the idea of a ship traveling from star to star setting up colonies. you get very high marks on this video sir..👍
On your schematic of Aurora, it says the atmosphere is 13.1% oxygen. The only way it would have that amount of O2 in its atmosphere would be if it already has photosynthetic plant life, since there is no natural way for O2 to be produced and constantly recharged(since everything oxidizes). It would be possible to tell the atmospheric percentages of the planet using modern technology using the spectrum of the planet as it crosses in front of a star or if it crosses in front of its own star. so that would be a big reason for humans to go there(earth like planet, with o2 rich atmosphere, meaning it has plant based life). Great videos, my first comment on one
A great subject for a long tv series.
Only a few minutes in and you covered my thoughts on interstellar colonies - that, after living for so long in a colony ship, people might not want to live on an actual planet and might prefer to build O'Neills and McKendrees or other orbital habs that rely solely on rotational "gravity".
Disadvantages to a planet include its gravity well and thick atmosphere that have to be overcome to visit your neighbours. If the escape velocity from the asteroid you've turned into a colony can be achieved by someone with a space suit and a fire extinguisher, you're probably better off sticking with the artificial habs because space flight becomes dirt cheap and you can go anywhere in the system with relative ease. Why drop yourselves down a huge gravity well if you don't have to?
They could get far more resources remaining in space than they could from any single Earth-like planet and do it a lot cheaper. Move everything that's likely to hit their habs into a safe orbit - preferably one huge easy to access ring around the star or some suitable large body - and then dip into it whenever you need something.
Great episode.
This is the most amazing channel I have ever come across, Issac Arthur is truly inspirational.
Yes! Last time I was excited by your enjoyment of the Ender series, now it's Ben Bova! I can't wait for you to drop the next couple of authors you enjoy :D
I found your channel after your collaboration with Fraser Cain, and after watching several of your videos I just have to wonder to myself how I never found your channel before. I love your videos!
:) Thanks. The channel is still pretty new, I've been calling this the end of year 2, but the channel is technically 27 months old and around 80% of the episodes are from the last 8 months.
Well done on another great video and thank you for expanding my knowledge once again. I can't wait for next Thursday
YEEEESSSSS!!!!
what the heaven. So good So good!
+Isaac Arthur -- Merry Christmas and a happy and successful 2017!
I very much hope you'll have gotten to 100k subscribers at the end of year 3
Peter from Vienna
Great video and l love the dedication at the end.
Thanks, it seemed right. By freaky coincidence Glenn was already in the video when I got the news right after the last came out, I'd had a different ballot with various astronauts on it and I was taking a break from working on that to check the comments and saw he'd passed away. I felt obliged to modify things a bit at that point, and it just seemed right to go with the dedication too.
An awesome conclusion to the Life in a Space Colony three part mini-series! I can't wait to see more of your videos! Keep up the great work! :)
great video as always
I would like to see a Ken Burns style documentary series about Unity's colonization of the Aurora system.
I was on that trip.
Sorry about about that population explosion chief.
Good series.
Loving all of your work, you need your own to show!
164 likes, no dislikes, you're doing even better than last time I checked. Keep it up, Isaac!
Always makes me happy to see these posts! Keep up the great work!
No offense man, but I litteraly use your documentals to sleep and always have excellent dreams about space, obviously and if I have time I end them the next day.
Love your work man.
Ok who else demands a regular weekly Unity Series bringing us constant reports from the colonies as they grow and expand? :D
We visit them again in the Interstellar Travel Challenges episode and once more in next week's 'Dead Aliens', I have to admit I've grown fond of them as a narration device.
I am a professional CGI artist and would love to make some high quality/accurate renders of Unity.
No u dont
@@melvinjansen2338 guess not, otherwise I would have by now
This is the best thing I have found on TH-cam been watching your videos non stop thanks. New subscriber.
Realistic and inspirational y
Written
These videos always make me so optimistic & excited for the future, until the video is over & I look at the world we live in. I can't believe we'll make it off earth anymore. Humans are just too broken (unless like in Interstellar, NASA goes off & builds things in a secret bunker while the world collapses).
Thanks, great video!
Oh my god so close to 30K! keep up the amazing work dude!
I would think a priority, before leaving for the next system, would always be to build more lasers for a stellar highways. Just say'n :/
i love your work, gives me so much to think about
You rock. This channel deserves so much more suscribers and views...
i think the most interesting concept is perhaps someone living forever on one of these things forever making and leaving new colonies
awesome videos by a guy i could listen to all day. thank you for the best space science videos on youtube. cheers m8
Bravo!
