- We often discuss the notion of settling the galaxy but do we need to stop there? This episode will examine the additional difficulties with traveling between galaxies and ask just how far we might be able to journey even without faster than light travel.

Isaac, your voice of optimism and hope for humanity’s future is extremely refreshing. Thank you for all the effort you put into your videos!
Thanks MAtt!
Matt Wild Indeed. The cynicism and dare I say *anti-human* perspective of many futurists is annoying. Even in the comments section you'll see a comment like "Will us stupid humans ever reach that point" or similar.
It really does bug me, we're the only known species that can even imagine an alien, compose a symphony, write a poem, yet contemporary people tend to view humanity as *only* savage and violent, in the context of alien civilization.
They always assume aliens will be some perfectly moral utopian species. Which is ironic because that idea speaks to the ultimate virtue of humanity, always striving for better than we already have. Well, most of humanity.
@@barahng I agree. The reason I stopped watching Kurzgesagt was because of how damn cynical that channel was. We need more optimism in the world; things will only get better if enough people believe they can.
rally matt WILD
@@jamestown8398 This! I try to tell my friends and loved ones this all the time. Any time "well life isn't fair" comes up, my reply is "it could be, if we tried."
Your deeply romanticized notions of futurism, human endeavors, and exploration always brighten my day. Keep it up mate.

You blew my mind
Hahahahahaharrrr!!OMG!!!
I could see an album of these
The day we are officialy informed about SFIA canon. We have arrived.
Isaac, Thank you. Your content lends hope, a rare gift in this world.
It's all stuff I dream of. But then I look around us and that hope grinds to a halt. While we have the chance of reaching life extension in our lifetimes and achieving agelessness, we're probably too preoccupied with who is racist or not. Society feels fucked, and science feels like it's in a decline.
+Kate Devils Don't lose hope there are allot of people out there who want better. To be honest all Science in the US has an agenda to push. Look at Europe with the two year GMO experiment those rats got mass tumors. Something is wrong with our food supply right now and the US is currently one big giant science experiment. High fructose powered obese children with ADD, Diabetes, and Autisim
What hope?
+BrewBrewBrewTheDeck The hope that these Autistic, ADD, crazed Diabetics, can turn our part of our planet around. Your comment covered mine thats why I replied.
I guess I should've been more specific. My comment intended to learn what hope Di- Raled derives from this channel's content and how. I mean, sure, it paints futures that might be considered appealing. But it doesn't really show to to get there so personally I don't see much there that would inspire hope.
IsaacHAMMER 200K interplanetary Boardroom Boardgame!
Great stuff man this channel is in a constant rise with no sign of stopping
Well since Isaac took over from Zephod its cannon anyway.
No he said 2100th century, therefore the year would be 20000 so wouldn't it be 20K?
Greenland Shark
The hundred years following 20k will be the 200th century, and the 2100th century will be the hundred years starting at year 200,000, almost 198,000 years in the future
Lol, I'd play a homebrew table-top game with Isaac as the DM. It'd probably be more fun than Warhammer.
@@beringstraitrailway Wouldn't 300 years following 20k, be the 204:th century?
we're in 2019, 21:st cent, (which begun a picosecond after midnight 2000) so 20K would be 21 milennia, 201:st century, so 20K+300y= 204:st century according to my math.
I've been with you since you had about 1.4K subscribers. It's taken awhile, but I've recently gotten my teenage daughter hooked on your channel now as well. Mr. Arthur, I have never seen her so inspired as she is watching your videos. I enjoy your videos immensely, but to see how you have stimulated my child's mind takes it to another level entirely. Thank you so very much for that gift. The conversations we now have, the questions she now asks.... you have opened a whole new world for her. Thank you. Happy Arthursday!
I'm very glad you're still enjoying them and that she is too! See you next year!
pretty sure you know this, but just in case, Isaac collabs with this guy- th-cam.com/video/4GemXQ2ARA0/w-d-xo.html he is also very good.. :)
You are the Brightest Star of the Internet, to me. Amazing episode, once again!
Jaroslaw Solak It's such a pity that there are no Polish subtitles to this channel. Maybe we should consider getting Polish part of this great community to adress that issue? It would really extend Isaac's audience.
If Isaac Arthur is the brightest star, then the Orion’s Arm project is a globular cluster!
You, sir, are one of the best content creator out there. Arthursday has become my second favorite day of the week, and i bet its the same for a lot of us. Keep up the amazing work
I am so glad I discovered your channel this year. So much great content. Keep it up and see ya next year!
This sentiment aged well.
I am a bit drunk, but nevertheless, I did shaed a tear at this outro, great job and keep being an inspiration. You can't even imagine how big of a difference putting into perspective everyday's life makes for so many of us, keep on keeping on and have a great next year!
ragir great word “outro”
It's hard to decide what's more mind blowing, the laws that created and guide our incredible universe along with things like Exploration, Colonization and Megastructures presented by Isaac OR the fact we get such beautiful videos jam packed with immense amounts of spot on analysis and facts along with personal narration by Isaac EVERY week! I am always blown away by the quality and mostly the obvious attention to detail and commitment to making every video better than its predecessor. That's truly mind blowing.
I'm only 15 but I have dreams and aspirations to become a astronomer thank you for expanding my knowledge Issac your videos truly captivate me
It's a great time to get started, I hope your dreams come true!
Good for you!! Remember one thing... Math.. Math... Math... And more math.... Lol. Don't give up on a dream! Never take No for answer and never quit...
Some Dude you may be only 15, but if you are passionate and find this topic interesting, throw yourself whole heartedly into it... After all, passion is the driving force behind brilliant minds!
thats awesome man!!! keep learning, we will need astrobiologists too, as we explore the planets of our solar system!!
Awesome buddy, go for it!
I'm sure that Isaac is truely happy and honoured to hear that he is inspiring a young man like you!
And like Isaac remarked: A great time for scientists in this field, many things to discover in your lifetime..
I am so grateful to have found this channel
Likewise. Cody'sLab gave SFIA a shout out a year or so ago and I'd never heard of Isaac until then. Now I'm one of those obnoxious fanboys who mentions this channel in comment sections everywhere lol.
I was about to point out that there are also stars between galaxies... but you seem to always cover everything 👍👏👏👏
There is also Dark Matter...
Not dark matter, dark matter is in galaxies. between them there is dark energy wich pushes them but andromeda is coming closer to the milky way on a collision course, making that dark energy non important for this
@@WadcaWymiaru that's if dark matter actually exists and is not a miscalculation
th-cam.com/video/0Mix9kQgfG8/w-d-xo.html
@@jebes909090 yeah we still don't know about them
@@jebes909090 It is not. And btw. I would not trust someone who uses Universe Sandbox to test astronomical predictions.
With the length and quality of your videos Isaac, it's amazing you havn't been picked up by a major TV network!
Better than many episodes! It makes me sad to think how much we will inevitably diverge, insofar as it means not being one human society anymore, not even just fractured facets of one like we are here on earth, but it's still a very hopeful thing to think about what is out there, where we're going, what COULD be, to try to solve the problems to do so. That's one thing that can always help break my depression.
From humble beginnings we started. No more will we miss our past forms as we currently miss a single celled organism or our cousin the chimp. Although, I may start keeping a photo of both on my desk as a reminder.
I'm currently subscribed to over 160 channels on TH-cam. This one is, by far, my favorite. I've seen every video and I oftentimes go back to watch some of the older videos on my favorite subjects. Since I love this channel so much, I became a Patreon Supporter a few months back and I get an immense sense of pride everytime a new video comes out because I know that, in a very small way, I'm contributing to Isaac's vision for this channel. Keep up the great work Isaac!
Thank you for your support!
I think this is the best sci-fi channel on the internet and there is lots more info in each video than the other TH-camr's videos, also these videos are way more interesting. :D
This was a good way to finish this year. Looking forward to next year's episode!
Love the graphics for this episode, they seem more realistic
This no doubt is probably your best video so far. Brought me back the same awe and curiosity when I watched your first video. It was the Kardashev scale. Such timescales are incomprehensible. People alive now are more related to Ameobas than a future crew that settles any galaxy on the Billion Ly scale. Even 200,000 is too much for me to comprehend. 200,000 years ago, humanity emerged and we were just struggling to live on Earth.
Thank you for the incredible amount of work you must put into this TH-cam channel. Your videos never fails to amaze me with the possibilities humanity has in the future
"I didn't live for 200,000 years by throwing dice". Planning to literally say and mean this one day. Great episode Isaac.
It''s been quite a year indeed! And now I can't imagine life without Arthursdays! May the next year bring many more amazing videos and discussions. My thanks to Isaac and everyone involved in these masterpieces that bring me so much joy and wonder :)
This is fantastic stuff - beautiful man. You are the seed of hope that grew the dream that saved humanity. Content like this saved the world in the future.
Yeah! I've waited for this episode. Really cool
Even by your high standards this one was a doozy, thanks Arthur.
Thanks Alex!
Arthur, your channel has been one of the greatest finds of my whole internet using history! Every week long wait has been worth it and I hope you carry on like this for many years to come! This time you have a great week, a happy new years and an even better next one!
Issac Asimov + Arthur C Clarke = Issac Arthur.
Superb.
Terminus.. sounds like a great place to start a FOUNDATION for a civilization.
:)
Thank you Isaac Arthur, you keep dream and hope flowing, which is the best New Year and every day gift anyone can get.
Yessssss another hopefull and positive view of "our" future!!
Thanks again Isaac :-) :-)
I just wanna say I really enjoy your content. As someone with a speech impediment myself, I find your videos motivational. They make me strive to overcome my shortcomings and become a well spoken individual. Thank you Isaac.
Thank you!
Yay. Finally it’s Thursday
Arthursday*
Hear hear
...my dudes
so?
youre amazing dude. what a year of incredible content
Been waiting on this episode for awhile now. Thank You for your amazing content.
What a great final episode for the year, here's to many more!
I have been watching since this time 2 years ago! I'm so glad you have reached a large audience, it comforts me to know how many others also share an interest for the inspiring and _awesome_ concepts discussed here. From the visual production to the writing, it has been a pleasure of mine to follow along in the journey, and witness the evolution of your channel!
Wishing you and the team a wonderful holiday season and 2018!
Commander Keen Such a great TH-cam channel!
Even his Comment section is one of the most pleasant on TH-cam! Rarely any fights or any nastiness.
Who says idealism and reality can't coexist? Issac proves that they can every time he uploads another episode
Thanks for all this amazing work your channel is captivating.
I like the Mass Effect method - look through a telescope from two and a half million light years away, take five hundred years to get there, and act all surprised when things are radically different from your observations.
Gallen Dugall, The travel time is not very relevant. It will be 2.5 million years later at the destination even if you did it in 1 year.
stefan r and add in the time dilation. So it would be at least another 2.5 mil in the future when you arrived. It would be nice to see more accurate space sims. The only two I know of are universe sandbox 2 and Space Engine, but those are exploration and education Sims. Although there are plans to add more functionality to Space Engine.
crazyahhkmed
Universe Sandbox^2 is the most accurate space sim there is though.
Dammit Isaac, That freaking buildup with the speech at the end of the episode 29:40 almost made me burst into tears. I am too weak to this kind of pathos. Just amazing.
these were great 3 years of debunking SciFi BS & opening minds to an even greater "reality"!
Thank U, Isaac & the whole SFIA crew!!!
JG R *Are
Some SciFi can be BS. Thanks god Star Trek is all real and even the SciFi bits are made of real science.
Promises to be an even more fascinating episode than usual ! Because if humans achieve this, they probably wont be much the same as us, since, as he has stated often, that cultures diverge quite fast.
Thanks, Arthur, for being a voice of hope in an otherwise dreary time.
Also thanks for being the kind of guy who takes the time to interact with his fans. That means the world to many of us.
The best futurism channel on youtube !! :) & cheers for all the "stella" work Isaac ! :D
Anyhow, here's am idea for a theme, what would it take to bring Sci Fi space ships into reality ? Such as the Gundam Mobile Suits or an X Wing etc. :)
Opening statement of Warfare Episode: "[...] as cool as they look, giant robots just are not practical war engines."
I for one would love to explore a SFIA timeline for building a starship like the movie era Enterprise in drydock, even without the warp propulsion, or even the plausible construction of the Unity arkship.
Yep, they wouldn't be practical but they would be fun !! :D especially things like the Gundam Mobile suits etc. The enterprise would make a great space tourist destination in low earth orbit :) I also thought that a full size Star Destroyer made of aerogel would be great for hoovering up space debri and it would look cool.
I just thought it would be a fun subject to explore what we could create for fun when space tourism finally kicks off, how close could we get with current physics to making these things come to life, it would be cool to make an X wing that is fun to fly, even if you only had 10 minutes of juice etc.
Just thought it be a frivolously fun subject to explore,
Fun things to build for space tourists to play with :)
Given the number of likes my suggestion got I reckon this might be a popular episode in the series ;)
Go on Isaac, do a frivolous fun episode for us wannabe space tourists :)
freezatron
Honestly, there might be some use for phisiomorphic (that is, mimicking phisiology) machines, because they might be easier to pilot or remotely control, even with the aid of cybernetic control devices - it would just be more natural. But I do agree that they are otherwise highly impractical implements of warfare.
Been watching random TH-cam videos for years but this is the only one I've ever returned to over and over again. Due to this, your channel has become my first ever subscription! Keep up the great work!
Let's move a galaxy around... because we can.
As amazing as the universe is, it is even more amazing what we could do with it.
This is the most original channel on TH-cam... for a given value of original.
And a thanks to you Isaac, great video.
Isaac,
I just wanted to say your channel is awesome. As someone who absolutely loves science fiction, and absolutely loves cause and effect, reasons, logic, articulation, and all the wonderful trickle down effects of human behavior, your channel is an inspiration to me. It regularly shoots down the regular sci-fi stuff and replaces it with all the things that make life great.
I also love writing hard science fiction, as it's a test of my abilities and everything I love coupled with the ability to dream. Your channel is always filling my mind with great new concepts (this episode the Shkadov Thruster which perfectly fits the bill that I needed and hadn't yet heard of), and touching (and improving through thought) on concepts I've already worked on or planned.
Thank you for inspiring and challenging me. Please keep up the great work.
A big like and a big thank you and an even better year to you.
Thank you Mario, you too!
These shows are so much better than anything on television. Issac, I could watch your shows non stop. Your incredible and your hard work shows in every episode. Please keep,up the hard work, there’s so many of us that appreciate it. God bless
Season 3 of a weekly show format, last week of December, and it's episode 52. Haha you certainly have one hell of a work ethic!
Yeah the format kinda makes the seasons redundant, I almost switcher over to just numbering them, this would be episode #114, though arguably anywhere up to 120 if we include a few specials etc.
these ideas are so much bigger than in traditional science fiction. i don't know anybody else who has suggested that integalactic colonization is practically considerable with slower than light speeds.
One of my favorite channels, keep up the great work!
I have watched this particular video several times, because I like the idea that even if I am long since gone that humanity is out there still reaching, still traveling, still surviving and still exploring. And our universe may be huge but we still want to tackle it.
As always, thank you sir! I hope we see more of this kind of discussion in the coming decades!
Hi, Isaac Arthur, I think in the future technology there will be more cars and more things like tablets. I love technology. You can say I'm obsessed with it. All my life I had some kind of technology! Written by a 7-year-old fan.
She is learning more every day makes her mother proud. I think it is important to keep tight control of how we apply new technologies. Some(tech) can be more harmful than is at first apparent. Having said that it is also important to push boundaries within reason.
Isaac, Firstly, thank you very much for all your thoughtful work. Fascinating, as always.
I had a thought for you regarding the Fermi paradox. Many of the counter arguments to the possibility of intelligent alien life fall into a group with an explanation like 'a particular species might do that but would all species necessarily do that'; as in: 'a particular species might respect our development process and leave us alone but not all species would'. One counter argument to this reasoning that I never hear mentioned is the likelihood that if there are a number alien civilizations in our galaxy they would probably carve it up into regions of influence so as to avoid conflict, just as we do with our planet. This greatly increases the chance of alien civilizations since we would only have to be in a region where the aliens choose for whatever reason to leave us alone. There's the additional consideration of seeing no Dyson swarms but I wonder if, once nuclear fusion is perfected, we won't consider solar power to be obsolete.
I also wanted to mention that you might want to vet your graphics a little more carefully. This video had galaxies spinning the wrong way, twinkling galaxies and a galaxy with a giant star in the center! I quibble, but these images are a little distracting.
Again, thanks for your great work.
S.
Oh sure, this is a variation of Self-Quarantine I think I've mentioned in passing, and should probably discuss more, but it doesn't apply to the DD, remember the Dysons, name aside, are really just an example of the concept. PErfect nuclear fusion and you still end up with one, because you want to soak up the hydrogen from that sun or use it as semi-free if you can't, but you still have the swarm, just more spherical than spherical thick-shell, as that has to do with packing habitats as close as you can to minimize comm lags and travel time without overheating, creates a near identical appearance.
Isaac Arthur have you seen the evidence of planets orbiting inside the photosphere of red dwarves? One solution could be the high likelihood of life evolving bathed in uniform red light but unlikely they develop space travel due to a lack of visible stars and the tendency of red dwarves to flare, thus killing that life
Thanks for responding. I wonder if we'd end up putting habitats close together in a shared orbit, maybe in the asteroid belt for materials and perhaps connecting them with high speed rail.
guitarovich, did you mean to say "inside the photosphere of red dwarves"? This is rather unlikely. Planets will not form inside of the photosphere of any main sequence star. A planet the collided with the photosphere would experience drag force and descend into the star. The photospheres of red giants are much lower density and Jupiter mass planets could remain in orbit for a while. There is something called a Thorne-Zytkow object which has a neutron star inside of the photosphere. Not a likely place for life to evolve.
Seth Turner We haven't found any megastructures thus far, but the universe is a very large place. It takes time to analyze other star systems, and we only have a limited number of telescopes that are operational at the moment which can actually see a megastructure like a dyson swarm. From our limited supply of telescopes, the time that each can look for signs of life is lower than you would expect because usage is often being rented out to view things that scientists (who are not searching for signs of life) want to learn more about.
I don't think we even have full coverage of the night sky in every practical wavelength yet. So we could be missing extremely obvious signs of alien life, because we aren't able to look in the right place at the right time.
Couldn't thank you enough!!! It feels I'm still watching the original Cosmos.
THAT END MADE ME CRY
pedrolmlkzk Industrializing the Moon got me
These videos never disappoint. Better than watching Nova on PBS when I was growing up. Thank you for all the work you put into your episodes, they're very enjoyable.
Awesome as always, thank you Isaac, for your great videos every Arthursday :D
Ever since I first found your channel I've been hooked to the amazing content you put out week after week.
But it is just now, at the end of this year, that I really want to thank you for doing this!
I may have kept silent for the past, but your work just has to get every credit it can get!
Thank you so much! Thank you for creating what so many minds are starving for!
Thank you, I really appreciate that, it's been an awesome year
Neil DeGrasse Tyson and Michio Kaku ain't got nothing on my man Isaac! You sir, are the Carl Sagan of the Internet Age. Thank you so much bringing these topics to the public's attention. Looking forward to seeing what you've got in store for 2018.
Thanks Michael, though I am a NDT fan myself :) 2018 should be a fun one, plenty of topics still to do
I just can't get over how astonishingly "knowledge dense" Isaacs videos are. Every sentence contains another thinkers full paragraph worth of content. You're the neutron star of ideas Isaac.
Thank you for the inspiration in hard times, you do us an amazing service.
Best channel on YT. Congratulations on a stupendous year 3, and wishing you all the best on season 4...I know I'll certainly be tuning in every week. Your commitment to detail is beyond my ability to adequately praise.
You know... I've been thinking, I really like Isaac Arthur the futurist... but what would it be like serving under/with Isaac Arthur the futurist....
I'm thinking MacGiver with a bigger imagination...
Other Guy- ' How do we get out of this mess?'
ArthGiver- 'Someone get me 10,000 paper clips, 1000 rolls of duct tape, a spark plug, a beer can, and a pinch of Essence of Chuck Norris...
We will build a helicopter and make our escape,
... while achieving ALL of our objectives,
...ending this war,
... Capture the dictator alive,
.... end World hunger,
....bring the Dic to the Hague,
... then eat an early lunch.. or a late breakfast if you so choose..'

More like "if you bring me 2 billion paperclips per second..."
Once again a mind-blowing video. Great job! Let me apologize for the long post first, while watching this video I had the following idea for a TV show.
The show starts with the departure of colonization ship from earth. The mission goals are to reach the end of the universe and colonize the way there without stopping.
The year of departure is 2100 and we have fusion and A.I. (Halo like).
First season would be about the ship acceleration, gathering of resources and colonizing the first solar system. At this time is like a generational ship where we grow and train people to colonize.
Second season would be about creating new technologies to enable stasis and nano-building robots that can build anything from matter. In this season we colonize 10 solar systems.
Third season would be about the development of transmutation, where we can now have multiple copies of people to colonize more efficiently, so for any system that is on the direction that the ship travels is now being colonized. The crew is now ultra advanced with amazing technology moving ever close to their destination and thinking about what to do next...
The fourth and final season is about the expansion of mankind. It will go back on the opposite way the ship traveled and show the multiple lives that the original, or descendants, crew that left earth. Final episode should be the arrival on earth (or the spacial coordinates of earth should be).
It would be scientific accurate, as much as possible anyways, and show that we never found out any solutions that violate the laws of physics.
If anyone is interested please use this idea, I just would be so happy to see it on TV someday.
Yeah that could be cool dude. I like the scope of it. In a way it reminds me of Roots the 1977 miniseires, in the way it follows a group of people across generations. The first season could deal with people coming to terms with the fact that they're going to live and die aboard the ship. Kinda sucks for their kids who get no say in wether they want to take part in the mission though... some nice drama to work with at least. Lets hope it gets picked up!
If anyone asks me if FTL is possible, I'm always going to answer, "It doesn't seem to be in the cards..." I've been conditioned. :)
Acknowledging the unlikely possibility of FTL is the 1st rule of warfare.
Nah, it’s totally on the table. Gravitational Waves is probably the best evidence that we have for it. We just need to figure out a way to warp the fabric of space time to our advantage.
@@yakarotsennin3115 Gravitational waves, if anything, prove that even warping of the space time itself is also limited by the maximum speed of information as electromagnetism is.
laszu Hmm that’s true, but what if you contract space and expand it in a way that would mimic wave propagation?
@@yakarotsennin3115 You are talking about the Alcubierre Warp Drive, which is only possible under known physics if we could generate negative mass/energy and how are you going to do that with only positive energy?
Isaac im a young fella but i LOVE your work and all it represents
Since i was a little boy i’ve loved space and your channel just makes me love it more
THANK YOU
What a surprise of a channel!!!! thx for doing it for us mere mortals :-p
Love this channel so much. Every episode blows my mind and makes me excited for the future.
I love how optimistic you are. Especially the ending, where you refute nihilism.
Thank you Isaac, these videos are some of my favorite things on TH-cam. I look forward to Thursday every week now.
Im genuinely giddy when these come out, great content Isaac!
Thanks!
I love your videos. You apologize for your speech impediment, but I think that it gives your videos a unique character. I LOVE your content.
Excellent video as always Isaac. Happy New Year, and may 2018 bring you everything you wish for! *maybe even the miraculous appearance of a blueprint for an FTL drive you can keep secret from your inquisitive fanbase
Happy new year!
YES YOU FINALLY BROUGHT BACK UNITY! I know I'm late but I just got to this episode. I've been waiting for this for a looooong time. Thank you Isaac!
Issac it's been fun to listen to you improvement! I love you man.
Hey Issac, long time viewer, here, love your vids! You do a great job covering the more cutting edge aspect of science fiction while remaining firmly grounded in known science. Keep up the great work! I hope you'll make a new Civilizations at the End of Time video, that series is awesome :)
Thanks Abhiraj! And yes we will be revisiting CivsEndTime in a while, probably not till MArch at the soonest and maybe april, but we'll likely do a few in short order, as prequels though, this today is arguably episode 0 of that.
I am almost crying. I really needed this today.
Your videos are so mind-blowing that I need to ration out how many I see at once to keep any mind left at all.
An observation. You mention correctly that metallicity increases with time and state that this will produce more rocky planets. I was doing a review of astronomical papers for a BIS Fermi Paradox talk and planetary body production corroborates with metallicity, however it allows protoplanets to hold onto more gas during the T Tauri stage so preferentially favouring gas giants over terrestrial rocky planets, indicating there is an optimal metallicity for rocky body formation. That said a great episode, I agree you need to get anywhere quick when you are talking inter galactic as more time means an increased likelihood of another IS civilisation getting there first.
Yes you could end up with more gas giants, but I don't think many rocky Earth mass ones, not including H/He, close to the sun, would avoid stripping of that,t hough its hard to say. Someone may have modeled it in detail but not that I'm aware. Still yes,w e could see an optimal metallicity for Earth-like planets, but I'm guessing if it is, its at least a little higher than the norm for ones forming in the last 4 billions years or the next few billion.
It's not so much another civilization getting there first as much as another one evolving in place and colonizing their OWN galaxy before we can get there! As far as the increased metallicity as time goes on, remember that this allows more stars of lower mass to form. We can begin to get red dwarf stars starting fusion at their cores as metallicity increases below the assumed 8% sol mass required for this. This alone would increase greatly the possible number of planetary systems as time increases and put them around stars with as much as 10 trillion years life span.
A 2016 survey of 406 Kepler objects concluded that the ratio of gas giants was x (>3.9 rE) x 9.3 more likely in high metallicity (>+0.3dex[Fe/H]) and only x1.72 for terrestrial (
Another fascinating look into the wonders of possible cosmic futures... Many festive returns to you and yours, and I look forward to listening to many more meanders through the infinite possibilities of imagination!
And to you and yours as well, happy new year!
Nice new cover footage

Imagine pulling up in an entire gas giant system megastructure-rigged into an impossibly huge intergalactic colony ship like “get in losers we’re headed for Centaurus A”
Your channel is the best thing I discovered on TH-cam this year. Thank you so much for that weekly episodes, they're great thought-provoking content with awesome music and visuals.
Looks like you have a GREAT upcoming schedule! Looking forward to it. Thanks for the hope.
Issac I recommend the scifi book 'bobiverse' the first book is 'we are legion; we are bob.' It's about a human dude named bob who became an AI whose primary mission is to colonize the galaxy. This year I've read the entire Dune and foundation series, however while I love both of them I finished the entire bobiverse trilogy within a week. Great writing, good science and just a simply good all around happy fun time read.
The audiobook is very well vocalized, for cheap readers who wanna try it out the first book's audiobook is on TH-cam.
:) I know the author, Dennis is actually a regular visitor to our channel's facebook page, which is approriate since it was one of my admins there who recommended him to me about when book 2 came out. I agree with the sentiment, great trilogy, great narrator too, Ray Porter was absolutely perfect for that trilogy.
Perhaps you don't know those pre-historical civilizations on the earth had extinction due to darkness experiments to kill people and use their body as AI. Then dark forces had destroyed each other by nuclear wars.
Their madness criminals had punished by other galactic civilizations, and forbidden to those anti-humanity things happens.
Thank you to everyone who helps make this channel happen. Happy holidays.
Once digital copying tech is available, Isaac Arther should be replicated hundreds of times to ensure we never lose him!
Glad I found this channel. One of the best ones out there! Keep up the great work! And for the record... your speech is just fine! no need for closed captions here.
I see one of your videos, I watch it. I'm a simple guy.
What a great year. You videos have come a long way. Can't wait to see what you have to off next year!
No, thank YOU Isaac
My greatest scientific discovery of 2017 was finding this channel. Thanks for an amazing 2017 and best wishes for the new year!
