you people are too high on science fiction; space "colonization" is not possible in real life. You can invent magical device like warp drives but there's absolutely zero scientific basis to this. we know nothing goes faster than light; and even doing so would require an infinite amount of energy. Assuming even a completely not theorized technology that would allow for 10% of the speed of light it would take centuries to do reconnaissance on a potential habitable planet with a probe; let alone get there. humans; assuming they survive; simply don't have the attention span and you'd need 50 or 100 years to reach the destination at least; which mean no human would live long enough. The future of space exporation is automated probes and telescopes; if that's not exciting enough for you I don't know what is. Even a manned mars mission is very far away (and one could ask what would be the scientific point of it; or the point at all).

The reason why you might be observing an uptick in space pessimism lately is potentially due to the recent release of the popular science book "A City on Mars" by Kelly and Zach Weinersmith, which dissects the practicalities of space colonisation in great detail. It has hundreds of positive ratings on Amazon and seems to have been doing the rounds. I have read about a quarter of it so far and honestly from what I've read the research and effort the authors have put into the book seems to be exceptional. Would love to hear your take on it, Isaac.

@jasonwalker9471

5 ай бұрын

Indeed, great book. A bit focused on the short term (at least the bits I've read), but that's ok. I think the main goal of the book was to warn people that anyone saying "we'll have a self-sufficient colony of a million people on Mars in 20 years" is simply wrong about the scale of the challenge we face in making that a reality. And anyone saying "we can just nuke Mars and teraform it" is an idiot, as Isaac has pointed out. Just sending enough nitrogen to Mars to plump up the atmosphere and make the biosphere viable is a colossal task that would involve doing something crazy like freezing out the atmosphere of Venus and shipping it in chunks to Mars with trillions of cargo ships. In short, I think the point of the book was, "Elon Musk is vastly oversimplifying things yet again, stop listening to him, he doesn't know what he's talking about." Which is true. Every time Musk opens up his mouth about space colonization I cringe, because he's so very wrong about so many fields within the topic. He has a bad case of some Dunning-Kruger-like effect, but he doesn't realize it. That's what happens when you surround yourself with yes-men and fire anyone who disagrees with you. That said, I don't think the point of the book is to say that space colonization is impossible, or even that it shouldn't happen. Just that we need to aware of the scale of the problems, and direct our investments in people and technology accordingly. SpaceX is a good investment. Trying to throw a million people at Mars, then after the first 50k are already there finding out humans can't successfully breed in that environment, then cancelling the colonization effort, then restarting it later in a different way... that's a Musk way to do things, but it's also a wasteful and dumb way to do things. Both in terms of human lives wasted and of resources expended. "Move fast and break things" doesn't work when mass casualties are a likely result. Some people who don't like Musk (which is anyone reasonable at this point) read the above and think that means we shouldn't support endevours like SpaceX. They're wrong. We should. We just need to be smart about who we support, and how we support them. Intelligent application of our finite resources will increase the speed of progress. Dumping all our money on Boeing won't. Seeing SpaceX succeed and then dumping all our money on them won't work either. Their ideas and company culture will work until they stop working, just like Boeing's did. We need to be nimble in our funding, and not drop all our eggs (or hopes) in one basket.

@@jasonwalker9471 A million people on Mars in two decades is absolutely possible, most of the technology needed is damn near off the shelf at this point or with a bit of adaptation of existing technologies. The bottleneck is the transport system, once a reliable and resuable heavy lift rocket platform is solved then it can be scaled VERY fast with enough investment and fast tracking of beauracracy. See Liberty Shipbuilding program, construction of three 14,400 tonne ships roughly every TWO DAYS, the vast majority of which was all done by hand. 2700 monster vessels in only 4 years. For comparison, Starship is probably going to end up coming in at 150-200 tonnes. Yes there is a difference in component complexity but automated manufacturing and scales of production drives these kind of costs down tremendously. Money issue for SpaceX is not an issue now that starlink is billions a year with subscriber counts only going up, numbers floating around expecting 30b+ in profits once market penetration is reached. Billions a year will buy you a whole load of starships once the production process is ironed out and you have vertically integrated most components. Everything is doable, the only real question about Mars is the gravity one. Is .38g enough for humans? We are about to find out shortly with lab mice in the ISS doing partial gravity experiments as we speak.

Even sending three (3) sail ships westward to brave the wide ocean required the promise of a shorter trade route that would solve all the financial problems of the Spanish Crown. No other civilization in our knowledge did anything similar, before. And we're speaking of sending 3 ships on a journey where they were supposed to return. Most likely empty-handed, according to the smarter people of the age, but return.

If a ship travels at a constant 1g acceleration rate it would get to Alpha Centauri in 3.6 years (7.3 years would pass on Earth). This includes turning the ship around halfway to decelerate. It would achieve 95% light speed in about 1 year. A 10 ton ship would require a mere 10 tons of continuous thrust. This is by far the fastest way we can get to other worlds and the ship would have gravity the whole way. All that is needed for this is a fission rocket that can put out thrust for long periods and does not consume hydrogen, you can't bring thousands of tons of that with you. A true fission rocket should consume uranium or plutonium only. 1 kg of uranium has the same energy as 120,000 tons of coal and plutonium contains even more energy, not much would be needed for the trip. Uranium and plutonium are jittery atoms that are on the verge of fissioning all by themselves, there should be a way to get them to fission in a linear fashion. What's needed is a controlled, time released nuclear explosion. In an atomic bomb fission occurs when neutrons hit uranium or plutonium nuclei. This is because they will not tolerate an increase in mass. Due to the equivalence of mass and energy the same should be true if you infuse them with energy. This might be as simple as having negatively charged uranium or plutonium atoms coming into contact with positively charged uranium or plutonium atoms. Or perhaps with laser energy. Or perhaps with electromagnetic forces. With the constant 1g acceleration method a ship can span the entire diameter of our galaxy in 24 ship/113,000 Earth years. Systems with stars similar to our sun can be reached in under 10 ship years. This is based on a maximum velocity of 99% light speed, there may be reasons to stop accelerating before that.

cant believe ive been watching this channel for a decade!!

I really hope so.

Thanks for your work on this Isaac. Interesting stuff. Can I request that people from the USA remember that other countries exist - and other hemispheres? Down here in the southern hemisphere, Isaac, the days are getting longer leading up to Christmas, not getting shorter. (But, incidentally, that has, in my estimation, negligible effect on feeling of stress or being "down." Such feelings at this time of the year probably arise mainly due to the disparity between the feeling of fun and self-worth that we had at Christmastime as kids, and comparing that to the lack of magic and fun, and, in fact, to the high level of responsibility without much sign of achieving our life-goals that we thought we might have under control by the time we were adults. Most of that isn't even "Keeping up with the Jones's" as you say, but merely fighting to survive (for many folks,) let alone feeling that things are in hand and we have many good plan Bs to take care of downturns in various areas of our personal scorecards. All of this is, in my opinion, a natural result of Capitalism running to its natural end - which will probably be our natural end, and, in fact, as such, is my personal answer to the Fermi Paradox!)

We are going through the Fermi paradox each on our own, ancient Egypt picked up on this the feather 🪶 vs 🫀 the heart, to survive you have to be light of heart and heavy in creation….. otherwise when you hour of judgment comes it’s definitely back to the black board 💛💎

Isaac - another excellent video. I have a minor complaint. At ~12:48 you talk about spreading out 100 lightyears, 60,000 stars. Remember, every star will have asteroids and comets - excellent resources for building space habitats, O'Neill Colonies. Beware of planetary chauvinism.

Our genus homo sapiens sapiens and our descendants are destined to spread out explore and occupy every nook and cranny that is available to us in the universe and maybe beyond .

200 years from now I would expect technology to be amazing.

I do think we can and should colonize Mars as well as other planets or moons.

Love the kiddos. You did good.

seems like we need to develop some centrifugal force habitats to determine whether living in space is feasible.

Yeah and here's the thing folks, even if we map every rock in the solar system bigger than a car, interstellar objects are still a threat. They can enter our range of detection with too short a time to do anything about it.

A bigger threat is probably long period comets from the Oort Cloud. They are not NEOs so we won't find them in surveys and they are moving fast in the inner solar system, so when we find them we won't have much advance notice if they are on a collision trajectory.

Why isn't being out there because we can be enough, exploring the galaxy and universe, learning and seeing firsthand what's out there instead of just looking through a telescope or space probes. I would love to be able to live the remaining years of my life out there in the galaxy.

Congrats on the formal adoption, Isaac!

Thank you!!

Space is hard... really, really hard, harder than anything humans have ever faced. I expect the first aboriginals some 70,000 years ago had the same opinion of Australia. Humans can be mighty when they try to do something.

I feel like there is also an economic incentive to colonize space. If the price of going to space keeps getting cheaper then it’s only a matter of time before someone starts to take advantage of that

Not without FTL travel.............

There is one more aspect of space colonization not discussed or rarely discussed - rouge planets not tethered to a star or star system. These will make transit across the galaxy difficult. Also adding to are possibilities of capture and or mining with these also being colonized. It is an added wonder of possibilities as there are billions of such rouge planets passing between stars but still held in our galaxy. But we may find that the void between Galaxies may also have such planets being islands in that not so void of space.

I personally believe that we must expand in order to attain larger amounts of energy for prolongation of our survival towards the Heat Death, basically, functioning like how life has evolved to function

It’s a Christmas miracle!

Hinges on if we manage to build AGI without destroying ourselves.
