Outward Bound: Colonizing Alpha Centauri

We've looked at colonizing our own solar system, from Mars to Venus, and all the way inward to the Sun itself and out to the dark edges of the Oort Cloud. In this episode we conclude the Outward Bound Series by heading to our nearest neighboring star system, Alpha Centauri, and look at the trials and tribulations of colonizing binary star systems and red dwarves.
A journey out to the stars to colonize Alpha Centauri

*****Show Note: Tidal Forces Error****** Just as a heads up there is an error when we're discussing tidal effects, I mention gravity as an inverse square-force, which it ism but tidal forces tend to follow an inverse-cube effect with distance, that's fairly important in this context as for instance an object 400 times further away than another (like our Sun and Moon) would have 400³=64,000,000 times less tidal effect not 400²=160,000 effect, of course the Sun is far more than 160,000x the Moon's mass, indeed it's 27 Million times the mass and hence has almost half the effect the moon does, on Earth, but a binary 10 AU away would be further diminished another 10³ or thousandfold, so measurable but hardly the big tide generator implied here. My apologies for the error, we'll have to save an in-video correction for another relevant episode, though I'll note it as one of the reasons I try to avoid episodes this long, errors like that are more likely to slip past the radar. :)

[@AlaskanBallistics]

Isaac Arthur thanks for the correction

[@MisterSquid1]

you could also make the rings rotate slowly accelerating to the speed you want for the planet so people of all colonies can go there without feeling sick during theirvoyage,maybe have spparate rings that will acceelerate at different speeds so they can get to the gravity of the planet that will be colonize in a way they wont vomit, as seen in the expanse and their children will also vomit if you sont do this since theyre used to their ring and people can go freely to the other rings whenever they want, also giving the abilty to repurpose the colon ship as a shipyard in orbit

But 80000 to 17355 the numbers are way to big to get realistic there and every message needs 4.3 from sending to receiving it. So to get a answer you need 8.6 years that's just madness.

@@abelgerli yeah i dont EVER see us colonising other star systems without, well, MAGIC really. But dont tell star trek fans that 😉

[@abelgerli]

@@alphatrion100 I totally agree but people dreaming about it without doing the math is nice but doing the homework should be done so people realise we should at first save our environment before dreaming about terraforming another planet. Even the starshot Projekt with 1g space probes for Proxima Centauri would have pumpt the energy production of the United Kingdom plus 20% into the space proble for seconds to accelerate it to 20% of the speed of light. You need the power plants for a UK to do it. With 100% efficient energy transformation into lasers to send the engergy to a 1g space probe because I'd they are not efficient enough you need way more energy than that. But the best part the engergy has to be converted by 99.999998 into acceleration and not in to heat. Because any efficiency less then that would just evaporate the 1g space probe and would not accelerate it to 20% of the speed of light. So even that's dreaming thermodynamics is the blogs man that spits into dreams because reality has to deal with real physics.

[@0122arendell]

This is amazing, could u possibly do a whole series like this where u talk about colonizing the closest sun analog systems to us, like epsilon eridani ( Ran), and tau ceti? Thank u very much

[@outandabout259]

The quality of your videos is astronomical. Thanks for creating them. And thanks for not posting then daily - I have quite a ways to catch up anyways as a new fan!

[@luminouswolf7117]

Ha I see what you did there

[@piguyalamode164]

"We have a lot of people interested in world building ..." . So will the colonists

[@epicspacetroll1399]

My dog had to get put down, but Arthursday is cheering me up a bit :).

[@Coastoghost]

Ah fuck, sorry to hear that. Been through that recently. Hang tough, bro!

[@HuntingTarg]

You're not alone; did you see the commemoration at the end of the credits?

[@jonathanhensley6141]

Videos keep getting better and better. Awesome video

[@mustwereallydothis]

I have to say, I'm seriously impressed. You are the first person I've encountered to have proposed a plausible reason to evacuate Earth. People talk about us needing to leave earth because of pollution and/or climate change as if the things they plan to do in order to survive in space and on another planet would not work here for some reason. How can anyone imagine it would be easier to transport billions of people several light years and either terraform a completely inhospitable planet or build thousands of artificial habitats than to simply fix the comparatively minor issues with the planet we actually evolved on? Even if we eventually manage to make the Earth completely unfit for human life, it would still make far more sense to create all those artificial habitats on or near our home planet. I'm all for humanity spreading out a bit but I don't think we will need such drastic motivations to begin. The prospect of making trillions from mining and the pure adventure of it all should provide all the motivation needed.

[@benjamincrom7276]

Wow!! These videos get better every week! I don't know how you do it Sir but thanks so much for your hard work and all the consistency. Fantastic video! Glad to see you finally getting more subscribers as your channel is incredibly under rated.

Condolences on the passing of your little buddy. From your remarks in various videos I know he was a good fuzzy-kin. _Ave atque vale._

I don't know where it is from, but DAM DAM DAM I LOVE LOVE LOVE this guy's accent. It's so weird and strange and unique I could listen all day. It's so perfect for the subject too.

[@o15523]

He actually has a speech impediment, although it has gone away some since he started the channel.

[@XxHybridFreakxX]

Love your videos. Hope you keep them up.

[@shade01977]

1:01 And a snuggie! I'm getting a snuggie! Seriously though, I am so excited for this episode. I have been obsessed with Alpha Centauri since elementary school. Thanks, Mr. Arthur!

[@donaldprescott5151]

[@mattbrewster8051]

This series is as fascinating as it is overwhelming.

[@jaysilentkarl5954]

This vid came up as an autoplay after watching how the universe works, but the title sounded interesting and I decided to watch it Now I am glad I did, thanks for the interesting and entertaining video.

These last three videos' topics were fantastic. Ever since I found out about you and your roughly 10K subs, I knew you were going to become a legend.

[@brandonnaidu8292]

Keep doing until the Alpha Centauri, Tau Ceti, Gliese 585, Kepler 1214, Thuban B, Dubhe, and the other neighboring constellations are build some settlements and trade centers.

[@brandonsyverson6935]

Great video as always! I enjoy the longer ones such as this one.

[@nortonwedge]

The inciting incident of this video is what I'm using in my own series. I remember you dismissing the possiblity of such a thing, I believe, so good to see you explore it in this video.

[@technologicalsingularitywi7734]

This channel gives SF information in detail
