Happy birthday Isaac ! I would like to personally thank you for this episode,since i was the one bugging you about fro about a year now. I am very satisfied with the result and i think that many other will find it useful. The one thing that is missing is a near-term solution on mining the atmosphere of earth from orbit for oxygen,so we need fewer spacex starship launches to refuel a ship heading to the moon or mars. Overall,great episode,thank you and happy birthday !
Happy birthday, Isaac! Another informative episode as always. And great to see some progress on the adoption front. Hopefully, things will be fully settled soon.
Happy birthday, Issac! Good episode! Congratulations on the adoption process proceeding. Geometry is a great girl's name! Wish them all a great future. If one of them becomes a tethered ring engineer in the future, that would just be great!
It's actually a boys name in this case, and a modification of the one he was born under :) He does seem to be the most STEM-tilted of the trio thus far.
i wish there was some discussion about collecting atmospheres that have been blown off the surface of a planet, like when isaac discussed the scenario of aliens blowing up a planet, and described the water vapor of the former ocean as "floating around the planet for easy collection" by the aliens
I believe some of Saturns rings are ice, that would be a pretty easy scoop and go proposition for Hydrogen and Oxygen anyway. Well, not really EASY, but you know what I mean. lol
For diffuse gas clouds maybe we use ion scoops. Drones handle all the solid & dense gas or liquid pockets. alternatively you can also wait for the ring to coalesce into a denser ring structure, maybe even shade it to aid in retention/condensation, & then mine the resulting ice like you would any icy comet.
Thank you for this video. I watch a lot of popular science, but it's first thing in a long time, when I was surprised by some big topic. Very interesting and after few minutes it's just: "it's so obvious, why I haven't heard about this concept before" - like with every great idea.
Forget the episode, I'm so happy for you, you family and especially you beautiful children, that you have all found one another. Wishing all of you the best.
I'd use hydrogen balloons on Titan: abundant supply (methane and water both abundant) and not much combustion worry. They could be used as cranes, building supports, and buoyancy adjustments for aircraft, submarine-like.
An oxygen/nitrogen mix may not be lighter than Titanian atmosphere, temperature being equal, but warm it up to standard room temperature, and it will have a strong tendency to rise in Titan's cold atmosphere. Hot air derigible, anyone?
Your pronunciation is so much better nowadays! Congrats bro! Just listened to your first and heard you mention it and heard this one immediately after just now. Couldn’t have been too easy at times but excellent growth
Came across this channel recently and I'm really enjoying the content! It's amazing what science can accomplish when using creative strategies and solutions. Also, Happy Birthday Isaac, though I guess it's a bit belated now.
Happy birthday, Isaac, and I'll repeat my congratulations on joining me in the community of adoptive parents. An excellent video. I will link to it in future when someone asks me why I think we should put more attention on exploring Venus as well as on Mars.
Ahhh what a lovely set of anniversaries! It’s so sweet to have all these overlap at around the same time. And nice name Geometry hoho. Geo is such a cool nickname for when he goes to school.
@@comentedonakeyboardforget terraforming. keep mining once the atmos is gone & then until the former crust is gone, & then until nothings left. Build many hundreds of millions of earth's worth of spinhabs with the mined materials. Maybe set aside some steel for the filler mass tanks on artificial planets for the few planetary purists left at that point. Even considering only artificial planets with liquid helium or hydrogen ice mass fillers we'd still be talking about many dozens of earth's worth of living area. Don't even get me started on matrioshka shellworlds. That's even better if you have the active support for it.
Freeze the CO2 into dry ice and launch it at Mars via orbital mass driver. Enough time goes by and you will have 1mb of pressure so you could walk around without a pressure suit and just a respirator. Then attempt to restart the carbon cycle using algae initially then move to more complex plant life.
Happy birthday and great episode and I'm so happy for you and your family ❤❤❤ and I can't wait for the next episodes, they sound very interesting! You almost made me cry, so happy for you!
***Which is larger: Titan or Ganymede?*** So for folks wondering, the episode's cites Titan as less massive than Ganymede but larger and that's an interesting point, as some noticed you tend to get disputed answer on the matter. Titan was originally considered bigger as it is, visually, but it does have that thick atmosphere. If you measure only the diameter in terms of 'hard surface', then Ganymede is a couple percent wider, include that thick atmosphere, and its not contest at all. Whether or not you should include that in planetary radius is tricky but we do use it for both Jupiter and Saturn's radii, so using it for their moons seems valid too. Though the ending of any atmosphere is very hard to define and its no wonder we often tend to prefer to use the solid or liquid surface of a world instead. Ultimately, in an episode about mining atmospheres, it seemed like it was proper to include that atmosphere in the moon. :)
You cover so many angles on every topic. It’s so easy to get lost in thought, after finishing one of your videos. Thank you, and happy birthday, happy anniversary, happy parenting 👍.
yet another disingenuous religious pillock. Issac might be fool enough to not know what sort of vile nonsense your ''holy'' book is full of, but the rest of us.. aren't.
Halo 2 was the first time I'd seen this concept. Missions The Arbiter and Oracle take place on an automated gas mine facility that hangs down into a gas giant's atmosphere on a cable attached to a massive orbital ring around the planet.
Happy Birthday Isaac! Hope you had an amazing day and wishing you many more to come! Love your work! Thank you for all the education and entertainment. 🙏
Happy birthday Isaac. You do a great job. And your channel is great. Always something fascinating to talk about. Really good food for a writers imagination. Thank you
After Star Wars my 2nd favorite SYFY franchise is Stargate. In the first series Stargate SG-1. In one of the episodes in the future they talked about the idea of being able to ignite and turn Jupiter or Saturn in a much smaller 2nd Star that could last million year or even longer if they could keep adding fuel. Anyway they talk about how this could bring much needed light and warmth to the outer solar system even helping warm up mars enough the north/south ice caps would melt creating an atmosphere.
Every time star lifting comes up, I remember Sar Wars' Star Forge being used as an evil factory of planet destroying eaviiil! While the reality would be quite different. Great video 👍🏻👍🏻
Glad you made this because I definitely have Cloud Cities on the Gas Giants and Ice Giants in my stories, and I definitely went the antigrav route, although it never occurred to me to make the Cloud Cities out of Diamond... 🤔🤔
I'm a longtime listener & subscriber, going back to the days when you routinely included a picture of Elmer Fudd in your intros. Congratulations to you on your tenth anniversary & the good news about your children. All the best to you, sir. Let me take this occasion to put in a comment I keep not posting. None of this should be taken as criticism or as taking away from your always worthwhile content. In an earlier century, when I was learning about such things, I learned about the simplest of hydrocarbons, whose name sounds something like "meh-thane." Occasionally we would hear it pronounced "mee-thane," but only in BBC productions. It does seem a bit odd to hear an American using that pronunciation.
I seem to recall some proposals back in the '80s for collecting gas from Earth's atmosphere for use in space, either by a ramscoop vehicle that would dive in and out or a collector dangled in on a tether.
Dear Isaac Arthur, Thank you for being open about your knowledge and goaĺs in advancing civilization. Thank you for hosting my evolving essay. My major purpose is finding people on You Tube that are open to the possibility that the second law of thermodynamics and its taxonomic root entropy is inferior to the highly supported finding that energy is not created or destroyed but may change form. Does anyone have hypothical reasoning that supports entropy as superior in practice to the finding that energy is conserved but may change form? Aloha, Charlie
HAPPY BIRTHDAY: and glad to see that life is good, for your next one perhaps a semi-serious one on birth"days" in a universe that stretches from the Planc scale to the Multiworse
I had gotten the impression that it was less 'Titan has a big atmosphere' than 'Saturn has a big gas ring that includes Titan.' Inasmuch as there's a difference between the two.
9:18 titan is cold. An insulated hot air ballon is likely the way to float on titan. You’ll need and use energy there. Just dump the waste heat into an insulated ballon than envelopes your vehicle. Vehicle stays warm. You float. Win, win. Titan is about -180C, (95K), so even a ‘hot’ air balloon at -80C would provide gobs of lift.
I think it's worth mentioning the obvious issue, that uranium enrichment in space would be relatively trivial, as compared to earth at least. A tall cylinder suspended from a rotating spacecraft could reach high levels of rotational gravity, and thus serve as an excellent centrifuge. While I don't think this would be a strong business case for space industry, launching is expensive after all, it would be an interesting issue when considering proliferation in space.
Since it came up in the episode, have you done a video on stellar based transmutation? Things like planet sized particle colliders used to generate transuranics.
