- Can we put our differences aside to advance humanity into space?
Or will we fall prey to our ancient instincts, evolved for a world far different from the one we find ourselves in today? And what could it be like to tour the inhabited worlds of the solar system a century from now?
In this lesson, the Terran Space Academy walks you through these issues, and takes you on that wonderful tour of the future our descendants, and perhaps we, if technology advances fast enough, can experience.

Love this kind of future because there is a real good chance that some of your predictions may actually unfold
Thanks !!
You are most welcome!
Wow doctor or whatever your official title is, you have hit all of the high production qualities on this one. War paint, nudity, future and history thoroughly mixed, advanced technologies, even a platform formerly known as CZcams.
Thank you so much... Short version ...really good Kentucky Derby 🎉 stuff.
Thanks.
Thank you so much, I appreciate your saying that.
The idea of seeing everyone as an individual has great wisdom behind it.
Thank you very much my friend.
If it were even remotely possible or practical.
@@snek9353 I have to ask, how is it not practical?
@@mustang607 Do you have time to get to know every person before you have to make decisions about how you react to them?
@@snek9353 Seeing an individual as an individual is not about that. One counter example could be looking at an individual in front of you while grouping characteristics of that individual with what your friend mentioned 10 years ago about her being bullied. Then projecting that feeling on the individual in front of you.
Love the vision of the future! Gonna need some of that mitochondrial therapy 😀
Look up QuantumTX.com. It's coming my friend. :-)
@@terranspaceacademy INTERESTING!! Got look through these tech papers! Thanks!
I tried explaining evolution to my 6 yr old recently .. At the end of it she said " so nana and grandpa were monkeys a long time ago?" I just laughed and told her no , it was long before nana and grandpa were born.
Reminds me of Huxley I think it was asking Darwin if he was related to chimps on his mother's side or his father's :-)
It is so hard to truly fathom a thousand years... Much less a million or more. We live such short lives.
Yeah... see, nana and grandpa weren't monkeys, they were something else, neither monkeys nor humans. We were born together with monkeys, like long ago old cousins.
Video starts @7:10 - as far as Moon tourism is concerned.. I wonder how we plan to preserve the Apollo landing sites in the future. Certainly, Apollo 11 would require the most protection. I envision a series of bridge walkways over the site so you can look down and explore the first landing without adding your own footprints to the historic ones. Something like that would have to be per-constructed, and placed on the site from hovering craft that is high enough not to disturb the ground. The only other solution I can think of is to make it 100% off limits to visitation.
I was thinking a 3D printed aluminum oxide dome starting about 500m out. The international limit for someone approaching someone else's ships. With glass tunnels suspended through and across the dome a meter from the ground... Then you could walk right through the site without ever disturbing the dust.
I really love your channel, I like the standard and professional look of your thumbnails, and I like the sound of your voice. You should one day do a video about Europa and if there is life in its underground ocean
Thank you so much! You'll like the second half of today's for sure! I would love to look at the biochemical possibilities...
@@terranspaceacademyalso since you were in the marines, I gotta give you some credit since many say that is the toughest branch of them all (I could only imagine what goes on there since I was never a part of it, I’m only 17 as of right now). My 10th grade English teacher use to be in the USMC, and you could probably relate to him. SEMPER FI
Semper Fi! It is indeed the physically hardest, though Air Force ICBM training was mentally harder. What are you plans my friend?
@@terranspaceacademy idk, I hope to join the Navy and/or do extra circular things to get a job in the energy industry or space industry
Quick question, the starship v3 they want to eventually construct that is much taller than the first 2 versions, would they have to do the free fall test again with the greater fap between the fins? Also did they nearly run out of fuel while trying to even get into near orbit, which is what I think the tank extensions are for?
They have two choices... Overfill and risk needing to vent a lot of propellant. Which killed Starship IFT2. Or put less and risk underestimating by a few percent what you will need and running short. The tank extensions are because, with the more powerful engines, you can launch with more mass and get more to orbit with each flight. The flaps should be able to adjust to the new parameters in broadside fall without design changes there...
@terranspaceacademy the need to vent would probably be better as it's more likely guaranteed that you will at least get to orbit, and the extra fuel will make orbital refueling that much easier. The venting part, could you explain why they would need to do that while still in flight, or could they just do that when in orbit in order to avoid another explosion?
The first 7 minutes are well spoken. I hope we can live up to them.
Thank you Lacie... I do too.
I've tried to figure out a way to make a fabric weave that allows a tube to bend while keeping a constant volume (over a limited range). it would use a huge amount of tiny pulleys and making a robot that could weave it would be hard.
That does sound tough... What about electroelastic polymers? Shorten or lengthen by current?
@@terranspaceacademy powered options including pneumatic are also options. but the power needs would make it heavier.
I have read the first three Foundation books multiple times. Are the rest as good?
It becomes more challenging to focus on the individual if someone constantly points out their differences. Also hard to focus on our commonalities when the 'ruling' class sees fostering conflict as an advantage.
"Boeing got their act together in the 2020s." Hillarious!
I will be honest here and admit that I also had trouble getting through the later books and am looking for the series to catch me up :-) Same with Dune... three books is about my limit.
NX marine?
Another interesting detail on your background might be a good topic for a video sometime I’m sure you have much more of interest there
Do any of your videos fill out the detail on how a spaceship can collect propulsive energy from the sun?
Or were you principally utilising a gravitational slingshot?
Great video
Cheers
1st Marine Amphibious Brigade :-) There is a lesson on catching Oumuamua that calculates the power that could be harvested per square meter in the corona... photonic and thermal. Converting that to propellant momentum would give an insane Isp and thrust. czcams.com/video/Uak7odKYIRs/video.html
@@terranspaceacademy interesting link thank you
Is Dr Robert Zuberand magnetic sale propulsion an option?
Cheers
The resources of just our solar system will last for thousands of years, if not longer. We will develop a star drive in that time frame, but will the people of Sol System even have the desire to leave? After all, we have this room!
Someone will! Probably about ten thousand someones :-) Mars One got a huge application list and it was basically a race to be the first person to die on Mars.
Hey Doc, great Lesson. Thx!
You are most welcome Dennis!
What a fun video, very imaginative. Good job.
Thank you Dan!
No warp drive?
I get beat up every time I get too hopeful but I think we'll have one within fifty years...
The evolution mythology is really unneccessary to the discussion of space
terranspaceacademy, this is 100% your and spacex's demographic. rocket science fans that don't believe in evolution. welcome to your primary audience. 😉
Kinda critical to follow the evidence when riding on a giant space machine...
@terranspaceacademy do you believe evolution is mythology or science? are you allowed to say or will it alienate you from too many of your fans?
Well done, of course, for saying that the soviet/russian Orlan spacesuits do not require such lengthy pre-breathing with pure oxygen of a person before each donning as American spacesuits do! It is good. However, you forgot to say that, unlike all American spacesuits for work in outer space and on the Moon, the Orlan spacesuit can be put on by the astronaut himself, alone, without resorting to any help from other people! And very quickly! The Orlan spacesuit is a slightly modified Soviet Krechet spacesuit, which was developed for the Soviet lunar program in the 2nd half of the 60s. And one copy of this spacesuit is available in one of the US space museums. You also forgot to say that the Chinese spacesuit is a copy of the Soviet Orlan spacesuit! You also forgot to say that now the Americans want to make new spacesuits for their new lunar program - and these spacesuits are also almost a complete copy of the Soviet/Russian Krechet and Orlan spacesuits!
The Krechet and Orlan spacesuits have a door in their back, so that in order to put on these spacesuits, the astronaut simply enters through this door, like into a house. This is the most brilliant invention of Soviet engineers, and it is hardly possible to come up with anything better! Therefore, all other countries have no choice but to copy it!
I didn't forget to say all that my friend. Half of it I didn't know until you told me. I thought the Orion was based on Sokol. Though since ULA used Russian engines until recently I'm not surprised they would look there for suit ideas... Every lesson is a question of what to put in and what to leave out.
P.S. Everyone knows that the Chinese are using updated versions of Soviet everything right now. :-)
Prophetic poetry! Thanks, Professor.
You are most welcome Jeff!
Another brilliant lesson my friend, kudos and congratulations. I dream of the day most of humanity pays attention to your wisdom and shares your visions and dreams. 🙏
Thank you so much! I do too my friend. We just have to hang in there a bit longer.
Everyones favorite teacher! Best space suit lesson I have ever seen. Wonderful engaging storytelling. Thank you. Plus, no physics homework tonight...
Thank you Mark! All numbers next week so no one gets spoiled :-)
Thank you, you just produced with as many times sadly lacking, an optimistic vision of the future that we can all appreciate.
Thank you John. For all the depressing news we see there are a hundred victories that don't get told.
Let’s make this dream a reality and change history!!
We're with you!
Terran Space Academy... At 5:00 to 5:17 of the video you say: "We see our modern selves as more advanced than our ancestors. The most superficial examination proves otherwise: We form teams and differentiate ourselves from each other based upon arbitrary perceived differences. This must change if we are to take the next step in human evolution!"
You make three statements there, and you are wrong in two of them. I will consider them one at a time:
----
Statement 1.
You are correct when you say that we see ourselves as more advanced.
-----
Statement 2.
You are wrong when you say that the perception that modern humans as more advanced than their ancestors is not true. Human nature, has changed many times. The most recent examples, in the near historic period, include but are not limited too:
(1) Agriculture, both animal and plant which allowed us to transcend the food chain that all species had been a part up until that point.
(2) Writing and later enhanced band-with mechanisms which allowed for the body of knowledge currently stored and used by living human brains to no longer be directly tied to and limiting of the body of all knowledge of the human race.
(3) Formalized leverage and wheels which allowed for the ambitions of man to no longer scale linearly with labor and thus be limited to the number of minds and hands that could be organized in one place and time.
(4) The extraction, accumulation, and transmission of high density energy forms be they electromagnetic, chemical, mechanical, or nuclear uncoupled the parameters of the natural environment humans live in from the parameters of the artifice they wish to build.
(5) And probably most importantly, the confluence of capitalism and the scientific method establishing a self-reinforcing cultural double feedback loop of culture of exploiting ever greater knowledge for ever greater progress producing still more knowledge. This has begun the decoupling of the progress of man from the social and political organization of man.
The book "The 10,000 Year Explosion" by Cochran describes how many of these changes have not just been additions to the technological kit of humanity, but have influenced our genetics and biological evolution. These are well and truly by any reasonable examination of the concept, advancements of HUMANITY itself: it's biology, its behavior, it's society, and its values, not just its tools. Perhaps what you MEANT to say is that modern humans are no more MORALLY or SOCIALLY advanced than our ancestors. Even that is not actually true. I recommend the book "A Farewell to Alms" by Clark which details that in fact human behavior HAS progressed recently and dramatically (including in many morally relevant dimensions such as organization, wastefulness, patience, studiousness, and tendency towards violence). Clark backs this assertion up with objective measures of behavior taken from primary historical sources. (The book primarily concerns itself with England 1100 AD to 1800 AD and the origins of the industrial revolution but contains contextual material going back much further and examining many other societies as references... the core thesis is that the industrial revolution happened because people's behaviors changed: they became more thrifty, more peaceful, more studious and patient... institutional change came as a RESULT of that pre-existing behavioral change with organization and institutions, and technological change later still. Notably, Clark concludes that the behavioral change happened without global intent, for strictly local reasons, without foresight... that will be relevant below).
No. the strongest possible true statement in the direction you are postulating is not "Modern man is morally no different from ancestral man." but rather... "Modern man has not advanced in precisely the same directions and to precisely the same degrees that some might wish." That's at least accurate, but is much more a function of the precise wishes of certain humans than of nature of humanity as a whole. Even if we assume that the enlightenment and correctness of those wishes (hardly a safe assumption to walk down such roads of good intentions as anyone with knowledge of history knows) dismissing the progress made so far is neither fair nor accurate.
-----
The last statement that you make, that we must divest humanity of "arbitrary" factionalism BEFORE embracing our space destiny is EVEN MORE WRONG!
The reason is deeply simple: It CAN'T be done. And it SHOULDN'T be done:
(1) Why it can't be done: Look at that list of 5 changes to human nature in the near historic period above. In every single case, the change to human nature was technological and the inventors of the technology had NO FORESIGHT of the ultimate effects upon humanity that they were causing... For example: writing was invented by various cultures predominantly as a means of managing taxes, land-deeds, and royal genealogies... It was invented by bureaucrats for bureaucratic purposes... not some grand sweeping vision of how humanity could be fundamentally altered.
There is EXACTLY no reason to believe that this lack of foresight can ever ever be overcome. Similar systems like chess are won not by looking ahead to the last move, but by learning how to play despite not being able to look ahead more than a very few moves. Even our best AIs can't play by looking ahead to the last move. It is WELL PAST TIME to accept that the future of humanity and human nature are a ship without a rudder. It is anti-historic wishful thinking of the highest order to maintain otherwise!
(2) Why it shouldn't be done: Factions based on "arbitrary differences" are a survival advantage because they allow for a more complete exploration of the space of all possible societal structures and values than any one more rich and unified culture could do their place. This is even more true in a world of advanced technological capabilities. There weren't many degrees of freedom in lifestyle or cultural organization for ancient man. Regardless of where he lived he had the same kit of about 12 stone tools for millions of years. Different human species and groups made them a bit differently, but basically these differences were refinements on technique not changes of underlying idea. This is why pretty much all hunter-gather societies tend to look broadly similar, and all subsistence farming societies look similar to one another... because of their relatively primitive underlying technologies there just aren't many different viable ways to live those lifestyles. But as we escaped from a small number of ecological niches and a built complex societies with differentiation of tools and technique and task and training, the number of possible ways in which to assemble viable societies sky-rocketed in a explosion of combinatorics. Increasingly we NEEDED a complex diversity of lifestyles and societies running on different and therefore sometimes contradictory sets of civic values... just to explore that combinatorics landscape for optimal combinations. That means, by meme theory, societies are and should be in a constant evolutionary struggle and competition with each other to a degree that simply was not possible or useful when distance made most humans and human societies irrelevant to each other and ecological constraints make them much more similar to each other. War has been an outgrowth of that competition and has served to identify more fit societal systems and values. I recommend "Carnage and Culture" by Hansen for a masterful exploration of how civilian values can dictate victory and defeat in battle.
The more advanced our technological capabilities become, the more tools and capabilities we have to organize our lives and societies. This means a wider diversity of combinations of possible value sets that can support societies that function and thrive... and thus a GREATER need for separate factions to explore that ever growing landscape of societal possibilities.

Conclusions:
Karl Marx imagined that after his communist utopia was achieved, a state of human existence would come about that he called "the end of history" because all the forces of social unrest (inequality and scarcity) that he erroneously saw as driving historical change would be neutralized. What he was really doing was evasively admitting to an end of his very limited understanding of humanity and human history. Too often, Space is seen as just such an "end of history"... a golden era without strife or all those negative human qualities, and thus one that can only be reached for once we have set aside childish things and become mature adults. And just like Marx, this vision is erroneous and only serves to betray a lack of understanding of just what humanity even is.
NO!
Humanity will go to space regardless of whether certain parties think we are 'ready' or not. In space, humanity will be kind, and generous, and curious, and intelligent, and tolerant, and virtuous, and it will love and grow there. But it will remain humanity... so it will also be intolerant, and cruel, and greedy, and violent, and selfish, and hateful, and impatient there too! No doubt, space will change us, but not that much!
You make a reasoned argument that I will study in depth. Thank you.
@@terranspaceacademy That's all any reasonable man can ask!
Just WOW, that is by far the best comment I've ever read in CZcams. I'm very glad I took the time to look through the comments and read this in it's entirety. I believe you likely have more to say that might be more controversial and would love to read it.
Thanks for the beautiful message
You are so welcome
and another great video! especially the first 5 minutes!!
Very glad you like it! Thank you!
Great video on a great future to look forward to. I wish they hurry up so I can see and experience some of the progress in my lifetime. 😄
I agree Steve... I'll probably be the guy to croak the day before they discover an immortality shot :-)
@@terranspaceacademy just hang in there. There’s going to be a lot scientific breakthrough coming and worth looking forward to. I plan to hang on as long as I can. 🤣
Thank you!
You are most welcome my friend.
Herein endeth the lesson. Amen Brother.
:-) Thank you
Well done. I agree 100%. It's not superficial things like looks, gender or race, it's about the individual themselves. As for the suits, it was interesting to see all the different suits. I liked the ship design, but was thinking, a sphere encompasses the most volume per given surface area. Since surface area = materials to make a ship, wouldn't a spherical ship be better from a mass and material standpoint?
I agree... We've actually created a few rough designs based on spheres. Remember the one in 2001? Prophecy.
Gender and race are not just superficial.
i didn't even watch it but i gave you a thumbs up anyway because im having so much fun at your expense. apparently they just give a doctorate out to anyone these days.
hey... you're not jordan peterson, by chance? 😂
As long as your having fun my friend. What "hic" makes you think I'm Peterson anyway?
@terranspaceacademy having a library card doesn't make you yoda. kudos if you get the reference.
peterson talks authoritatively on a lot of issues way outside his training. He transposes aspects of a discipline he studies over one that he doesn't and pretends the science is just interchangeable like a big lego set. 🦞
👍♥️👍😄

Like always love the video, but I hope that by 2125, the final three nations worldwide still utilizing the imperial system would have transitioned to the metric system! 😀
Indeed. But I hear some engineers proudly commending Tory Bruno for not saying anything at all in metric... :-) We are stubbornly proud of our backwardness sometimes.
The metric system is for people who count on their fingers. I'd hope by then we've moved past that.
@@snek9353 haha, true but is is better than being based on 3 barleycorns laid end to end for an inch or a yard = gyrd which refers to a stick! (edit opps spelling is hard) oh it was later defined by King Henry ( I think it was him) as the distance between the tip of his nose and his thumb.
@@clintmc8285 The meter isn't really any less arbitrary. Sure it's defined, but I don't know about you but I have no way to accurately measure the Paris meridian or the speed of light. If we were smarter we'd use something many people can measure, gravity works well for that. While it's not exactly constant throughout the Earth it's pretty darn close.
There's two good ways that come to mind to base a unit of length on gravity. The distance fallen in a vacuum in one second, that would be equal to about 4.9m, call that unit a gl(gravity length). Or a measure of barometric pressure at sea level which while it does fluctuate the average is constant and it's easy to measure. Measured using water it's equal to 10.3m. If we say it's 1/10th that, then that could be a bm(barometric meter) roughly equal to the current meter.
And in case it's not obvious I'd hope one day we'd be smart enough to switch to a base 12 math. That's what the imperial system has going for it, it's not solely base 10. Base 10 is dumb as it doesn't divide evenly by 3 or 4.
Family history trashed my prejudices by showing me how silly and absurd they are. Grandpa and grandma fell in love and got married in a small town. There were were a number of nationalities, races, and religions present in the town including blacks, Indians, and even Jewish people. There were also Germans, Poles, Fins, and Danes among others. There was much discussion. Even letters to the editor and a front page article over my grand parents marriage. The town was in a tizzy. It just wasn't done. How dare they. After all, how would the kids be raised? Would they be raised in the Danish Lutheran Church or the Finnish Lutheran Church? . . . They went to the closest one... That was pre WWII central Wisconsin.
Ah Wisconsin... I dare to say that the most racist places I have lived since childhood have all been North of the Mason Dixon line. The states with the highest rates of black incarceration, measured as a multiple of the percentage in the population, is New Jersey at 11.9x, and Wisconsin at 11.8x. Hawaii is the least at just 2.4x. The South never fell, it just moved.
Universal ugly is ugly no matter where it is and unfortunately it really never leaves
Clearly not a believer in catastrophism then? As you showed depictions of dinosaurs, a sly question for you. How did the ultrasaurs support their massive weight under gravitational and atmospheric conditions? The physical evidence suggests they were quite fleet of foot yet those who have run the numbers suggest this appears to be impossible. Interestingly, under gravitational conditions similar to those on Mars, all physical issues would disappear but this wouldn't fit mainstream models and theories would it?
How can I deny catastrophism and accept what happened to the dinosaurs? I just don't think it explains everything or happens very often. Regarding the second point, oxygen concentrations were much higher back then... Allowing larger animals to move more energetically than possible today. Indeed, it would not fit mainstream models to suggest that dinosaurs evolved on Mars and came here later, nor do I find that plausible. But I'm ready to change my mind if you find some fossils on Mars or other equally convincing evidence.
If NASA failed as many times as space X has, they would have been shut down, but here we are…
Indeed.
To the best of my recollection SpaceX has only failed once. NASA has failed more times than SpaceX.
😊 implicit bias is sort of a hoax
Measured, quantified, and proven my friend. Is the opposite of a hoax :-)
Is there anything in this one about the huge damage and setbacks commercial space has caused to the artemis program?
there's a lot out there on sls and orion setbacks but people seem less aware that spacex HLS is starting to look entirely infeasible. i mean... musk said this thing was supposed to be landing on MARS by 2019!
overwhelming bias is a commercial. 😂
I don't sub this channel for this BS.
Sorry you feel that way my friend but it is WHY I started the channel. For the bigger picture.
@@terranspaceacademy I get enough BS social justice preaching from everywhere else. It's not unique, insightful, or relevant, quite the opposite actually.
