- Far beyond our Moon and Mars and the other planets is our greater galaxy and its billions and billions of stars. And yet it is but a flyspeck compared to the enormity of the Universe beyond. Could we every voyage to these distant galaxies?

Congrats on the new role Isaac, it's incredibly well deserved! Thank you for all your hard work!
Our pleasure!
@@isaacarthurSFIA Considering that the oceans will boil in the next 400 years due to waste heat; I doubt humanity will be able to make airline flights, let alone intergalactic travel.
What's your take on how we should deal with rising temperature problems caused by climate change? How will heating up a planet 3 degrees affect rocket launches and take off?
We could just block 2-3% of the sunlight that hits the Earth, but that would require trillions of these things humans call monies.
@Jack Sparrow I doubt the oceans will boil in 400yrs
@@jimboscooter432 And I doubt you can do math, or know how bad the climate is getting.
Isaac, I’ve been watching you since my freshman year of high school, I am finishing my second year of college now, and it is absolutely remarkable how you have developed and improved your content and community, without watering it down. Huge congratulations for the new position, I can’t think of a better science educator for the role. God bless, and keep it up sir.
Indeed I remember the after the first few episodes I though “this guy is great, I wonder how long it will be until he runs out of Fermi Paradox questions to write about and the channel slows down?” But, I’ve been so fortunately surprised with its longevity and ever improving quality!
Amazing how much progress you’ve made speaking, Isaac! I didn’t know it was even possible to bootstrap your way out of a speech impediment, but hearing you say “mirror arrays” perfectly compared to videos you made 5 years ago - it’s incredible. I didn’t know it was even possible.
Thanks for bringing such great content! You’ll never meet all of us, but I hope you know that the numbers are real people, you’ve educated and sparked interest in science in literally millions of people by now!
Congratulations! I'll take this opportunity to say that people like you keep the dream of the stars alive in a time when all too many people have become defeatist about humanity's prospects. It is no wonder the NSS wanted you. You are a much-needed voice of optimism. Thank you for that!
oh algorithm gods! hear your servants' plea and spread this video!
We worship science here, sir. Hide your shame!
i have no shame and the only thing i worship is the cosmos itself.
@Dados, Ciência e Sustentabilidade It seems well hidden, then. I accept this, for now....
🙏
Hail, the algorithm
Congrats on your new role Isaac! With you at the helm, a future like this is more likely to come sooner rather than later.
And another wonderful and informative video.
Same.
This is the first time in forty years I've seen an *understandable* synoptic description of the galactic neighborhood. Add my congratulations and THANKS for your service.
26:27 “Longer is better” - Isaac Arthur
Congratulations Isaac! Your videos inspired me and even helped me go through hard times. I'm happy for your success. Well deserved.
Thank you so much!
Wow, I can never decide if these kinds of episodes are awe-inspiring, or depressing. A galaxy-wide aluminum tunnel, indeed.
This is how the paperclip optimizer got created. But instead of paperclips, aluminum. :D
When he brought into the idea the expansion of the universe making intraglactic spacelanes subject to being torn apart by the expansion of the universe... That's right, right? I don't know I just dropped right back into a speculative space without emotional investment.
They impress me, I love the graphics! But that's all we have, seriously. I think the comment-section is depressing as HELL, it just slays me that anyone can think any of us is going ANYWHERE in this context!!! It's really not sane.
Congratulations on your new title, Mr. President! We are all happy for you as our online Sci-Fi, Physics and Astronomy teacher with the best and easiest to understand videos about our Universe.
It’s weird how inspiring this stuff is when it’s almost certain that none of us will live to see it, but I guess that kind of thing what makes us human.
We can be the ones that lay the foundation, that build the groundworks for this brave new future. Or we can be the ones that lounge in obscurity and if anything make sure it never happens. Never underestimate the impact you can have.
I think there’s a decent chance some of us may well live to see this future. As Isaac said, live forever or die trying!
That’s what really inspires, is the things we leave behind, and the things we help bring into being, even if, and I would say especially if, we don’t see the ending.
@@mj6463 yeah, it’s not that we won’t live to see it, we’re seeing it right now, we just won’t see how it will end
Wow! Congratulations on the new NSS position! It's downright neat seeing one of my favourite modern futurist voices take the helm of one of the more futurist organizations in town. The more people across the lands who take the long view, the better.
"we look beyond the Earth, to greater worlds" yeeees, let us extend our reach to the stars above
Standing in a train station in central Austria after a hard day at work. This occupies my mind and makes me happy. There is no greater git.
Thank you for the videos Issac! Congratulations on your recent appt!
Congrats Issac 👏. Your channel is awesome. Thanks for the hard work.
Man I love this channel. I find myself excited everytime I see a new episode in my queue. Not that I ever receive notifications.
Piers Anthony's _Macroscope_ (the ambitious novel that didn't sell) has a peaceful galaxy with an information economy based on ftl communication becoming a warlike galaxy when ftl travel is discovered.
I loved that book. I read it back in the 70s, and I still think about the concepts covered in the novel quite often.
I've been watching your videos for quite awhile now and I can't think of even one that was not exceptionally interesting and informative. I'm happy for your new role and am sure you will be just as exceptional at the helm of the NSS! Well deserved, sir, well deserved.
Congratulations! Can't wait to hear more about it in your future vids. Adding an 'updage on stuff' to each vid would be great!
Always loved your videos ❤️ extremely insightful and easy to understand when you break down certain topics for us. We are truly blessed to have such an amazing and informative content creator 🌏
Dude huge huge huge congrats. You’re videos are amazing; realistic but also willing to think outside the box. Can’t wait to see what you can accomplish in the future 👊🏾
Daaang, isaac, congratulations! I mean, considering all the talks you give, deserved.
I love this video, you always shine New Light on topics that i have been interested in since childhood
Dude, You rock. Happy Arthursday man!
Congratz Isaac! Well deserved. Thank you for your Work.
Much appreciated!
Imagine moving a whole bunch of red dwarfs with your stellar engine of choice, and using them plus tons of relay stations to setup the ultimate laser highway between galactic regions. Very well might wind up with billions of people living at each "way station", acting as ports of call on the long trip between galaxies, as well as homes for those that want to live in a more "rural" environment. Congrats on the role there as well!
you do such a good job at these. perfect score and visuals
Excellent video good sir and hats off to the crew!
Thank you kindly!
Keep up all the hard work I appreciate everything you give us.
Ooooh! I'm gonna need some popcorn!
Awesome show. Kudos to the artists, writers, helpers and sound producer. Top notch content.
Super congrats Isaac!! Nobody better for the role!!!
WooHoo! This looks like a great one. Saving this one for tonight. Thanks, Arthur.
Congratulations Isaac!
Congratulations Isaac! Love your videos...
Love your content Isaac Arthur !
Congratulations on your new post, Arthur!
Fantastic video! Amazingly comprehensive look at our local environment - though I personally love thinking of the Sombrero galaxy as the next level of waypoint, so I was disappointed that you didn't go one more intermediate level out before the supercluster. Thanks so much for this and all your other videos 🍻
Another thought-provoking episode, thanks for that. Also, huge congratulations on your new role! Hope it goes well. I know you'll be a huge asset for them.
Thank you for the episode!
Thank you for your videos, they are the only things that keep me from having complete nervous breakdown. you seem to be the only person to have quite a lot of hope for the future.
Love your videos Isaac! :D
So happy you got such an amazing position! Great work my man!
Yes! Congrats Isaac. That was exciting news
Awesome video and narration
Thanks so much for this video! I’ve been doing a lot of world building for an intergalactic-scale story and this has always been one of the big hurdles I’ve had to think about when writing it. Currently I’ve been using made up space magic as a crutch, so it’s great to see a more scientific approach to the subject. Once again proving how slept on this channel is.
Glad it was helpful!
I'm so glad this channel is still going ☺️
Congrats on the NSS presidency! I have some concerns about the aluminum intergalactic tunnel, durability wise. If any high speed dust damaged it, it could make an area of intergalactic space far more populated with particles than it would have been otherwise, right? I'm no expert, but it seems like the mass and complexity cost of cleaning and maintaining that system would outweigh the benefits compared to our usual laser highway systems.
Also, just wanted to say how much I love watching a channel where we use phrases like "interstellar laser highway" on a regular basis:)
Wow I've literally been enthralled lately by what could be in other galaxies and traveling to them, perfect timing.
Followed this channel for years, can't think of anyone better for that role. You create accessable, knowledgeable and inspiring science content, as a layman I love it. Congrats! From a brit and fellow vet of the other sand pit, Issac🤟
Thanks Joe, I really appreciate that :)
Wowwww! Congrats on the new role! Happy for you!
Thanks for the video. 😊👌
To Andromeda and Beyond!!!
Thanks for the video Isaac.
Congrats, Isaac!!!!!!
Fantastic vision and work done ! ❤🎉
Congratulations Isaac!
With the potential of the future, I wonder if some civilization millions if not billions of the years in the future will build a, idk, gigastructure not around a star, but around an entire galaxy. I remember that the Nicoll-Dyson megastructure could move a star by reflecting the light in one direction. I wonder if this gigastructure could move an entire galaxy, therefore turning the intergalactic voyage from a "Go from Galaxy A to Galaxy B", to "Move Galaxy A to Galaxy B / Move Galaxy A and Galaxy B closer"
THIS content is why I subscribe to this channel.
Congrats on your new role, Isaac, I know I have no business feeling vicarious pride - but I do.
Congratulations, Isaac! And thank you for your channel. Your content has always provided me with ideas and inspiration for my personal sci-fy writing. I don't publish or at least yet. But if I ever do, you will certainly get credit. Even today's episode gave me a good idea.
thanks i love your channel. iv been a fan for years. gourmet food for thought
I would have never in a million years guessed that Saturn had enough material in it to make a pipe stretching from the Milky Way to Andromeda. That's nuts!
That "Welcome to SFIA" line never gets old :)
11:35 for reference
wow! Congratulations Isaac! I'm sure you'll do a wonderful job. I would love to see a panel with you and Zubrin one of these days.
Congratulations Isaac! You really deserve this honor!
Yes!! Finally!!!
Congratulations on your new role! I know you'll do great things for the National Space Society!
Yes, I missed your beautiful voice, sir Isaac and your scenic narrative
You are most worthy of all that comes your way! Thank You so much for the content and Congratulations-P@
Council of Giants: Make each one into a Birch Planet / Black Hole ship and gradually move them back homewards. We can start by practicing on the smaller ones that are "only" a million or so stars!
This channel goes great with Fraser Cain. Arthur is imaginative and inspiring while cain is pragmatic and informative. They go together like a drink and a snack.
Congratulations, Isaac, on your new position. Well deserved!
I was going to travel between galaxies -- but then things got really busy at work.
Really liked this video. I hope that humanity gets that far out into space.
Congratulations! that's amazing. I met you there last year, and hope i can make it to the next one too!
Congratulations Isaac 💪🏻
Wow! Congratulations!!
I love the videos with massive scales like this one! They really give you a lot to think about, and they challenge you to try to comprehend space on scales we never had before a century ago. Also congrats on your appointment!
They're my favorite. I love the idea that in some galaxy, possibly outside our observable universe, there are giant advanced civilizations like this. We'll never even know they exist but it's cool to imagine what beings, lives, and civilizations could be active right now.
Oh wow, congratulations, Isaac! That's fantastic news, man!
WOOOW!!! Congratulations Isaac!! I can think of no one else better suited to the role of President of the NSS.
What at treat to have a brand-new sfia vid pop up. Congratulations on your appointment, Mr. President.
Stargate Universe involved this, so many ways they could have kept it going😢
Good show though I think it struggled in season 2
Star gate universe wasnt that good. Sg1 and sga were much better
The star gate universe is honestly mesmerizing ❤ one of my favorites
@@spencervance8484isn’t that still the star gate universe?
@@Texasplit there are three series.
SG:1, SG:A, and SG:U. Im complaining about SG:U. Its awful. Maybe it picks up later, but the multiple episodes i watched were pretty bad
36:30 Buce Banner is giving a talk? The public indemnity insurance for that event must be HUGE!
;)
Congratulations on your new chair, Isaac!
Good work bro.
Congratulations Isaac, that is great news that you are trusted with such a responsibility. We all know you will serve above expectation!
Total respect, Brother !!! (Except for anything related to Mars, a total waste of time and resources, even training and science).
I subscribe top-level, like, share to text and posted this! Keep it up! I love your work!
God I love this channel lol, nowhere else will you find someone casually discussing the pros and cons of building tunnels through space light years long while also calculating the weight of the materials needed hahaha. Fantastic stuff, please never stop!
Congrats Isaac.
President Arthur has a fitting ring to it! Kudos!!
I love the idea of saying “screw you cosmic inflation” and building billions of stellar engines to move all the galaxies back towards us. The jokes write themselves, because it’s such a comical idea (even if it is fully possible and potentially desirable)
“We’ll take the entire galaxy, AND PUSH IT SOMEWHERE ELSE!”
“I’M TURNING THIS GALAXY AROUND. THAT’S IT, BACK TO THE LOCAL GROUP.”
@@oberonpanopticon lol
Glad I prepped my drink and snack before *this* epic journey ♥ x
Thank you for your optimism. It’s refrshing
Isaac makes my drink and snack so much better
This episode is especially amusing.
Congrats 👏
You so well deserve your new role. Best of luck🎉🎉🎉
I lost it a bit when you started discussing tunnels between galaxies. Indeed, this is very SFIA XDXD
Beautiful
Congratulations on your new role with the NSS - We could all use your optimistic take on the future..
