"Then there was the time that cycler came through the system and missed their turn. 300,000 souls flung off into deep space, never to return. No way for us to rescue them all. Even with maximum effort by the fleet, at best we'd be able to give them some extra supplies and bring back a small number. We figure they'll last a few centuries before their energy runs out, and that'll be it for them. I imagine in the meantime they may actually build a whole religion around their predicament."

Imagining the insufferable wine snobs of the future brings me a surprising amount of joy. In a couple thousand years, someone on a station around Alpha Centauri is going to grow some grapes, and make some wine, and it might even be pretty good wine. And they're going to decide to send it back to Earth, because a bunch of people want to send something back, and sending a ship at low speed just for sentimental value, a time capsule of a sort, isn't that expensive when we're sending much bigger ships onward and outward for more exploration and more new settlements. So they might as well. And it takes its time, and it arrives, and is all the more valuable for it because it is one of the first things to be sent back. And someone is going to enjoy that bottle of wine, probably someone with more money than they've earned, or someone who got lucky and won the lottery after a bunch of people agreed to just randomly choose who got it. But then there are the more day to day wine sharings that are enabled by technology. Some O'Niell cylinder at Alpha Centauri has an equipment malfunction that changes the soil just slightly and unexpectedly makes a great vintage, and they send the data from the routine soil samples along with a log of the light conditions, irrigation protocol, gravity magnitude, etc., and send it in the regular broadcast to other star systems. Sure it takes years to arrive, even decades for far flung settlements, but then they can configure a greenhouse to match the conditions, and grow their own grapes, and make their own version of the wine, making it cheaply enough for everyone to enjoy. It would become routine, every day you get the 5 year old news, discoveries, and fashions from AC, and at the same time, AC gets the 5 year old news, discoveries, and fashions from Earth. That is something that is going to be very interesting.

Almost! A cycler is on a fixed Hohman orbit. The first candidate routes would be likely to link Venus, Earth and Mars in a big lazy orbit. Two such vessels on opposing legs could move a lot of people and materials. I could imagine an orbital ring developing around Venus supporting gas harvesting and export to Mars, another around Earth supporting and feeding billions and acting as the gateway to interstellar travel, and a third at Mars that would be home to most of the Red Planet’s population, with heavy industries planetside. Your idea sounds good, I hope you develop it!

Massive trade stations essentially cities in space, rotating between planets stimulating trade and travel. That is amazing. Looking forward to mining and orbital settlements episode.

The Economist Paul Krugman once wrote a paper on the effect of time dilation on calculating interest rates for goods being shipped at a high enough fraction of light speed. While he originally did it for his own amusement, he did a through enough job that he eventually went ahead and had it published and peer reviewed.

The interstellar cycler castle is such a cool sci-fi concept. It might mean that aliens visit us for a little while every 20 thousand years, and have been doing that for millions of years.

Hearing that analogy about these cycler castles being akin to early colonial-era sailboats riding the trade winds, and transporting cargo throughout the trade route, got me thinking about something similar more down-to-earth: What if there were floating trade ports/citadels in Earth's oceans that travel slowly but steadily on the trade winds, delivering their bulk goods slowly, but cheaply?

By now it should be clear that Trump’s promises may be more, louder and extreme, but they too have been broken.

Since a fully populated Dyson swarm has more people than most sci-fi galactic empires, there is also a high chance of genetic and cultural divergence for isolated populations over the same timespans as needed for interstellar travel.

I would think Manufacturing Cyclers (at least for intrastellar use) would be a good fit.. it orbits between raw material sources (e.g. asteroid belt) and product markets (e.g.. Earth). Repeatedly picking up materials, and as it travels, processing them, and then creating consumer products to unload along the way. Not sure what it would carry for the return trip, aside from products needed by material sources. Perhaps keep a small surplus of products and have a "retail store" of sorts on the ship, for anyone in range to dock and shop at. Cyclerco Wholesale Corporation (tm). 😁

US capitalism’s decline continues as competing economies rise (China, the European Union, the BRICS countries, and so on). The rich in the US use their wealth to grab and hold everything they can amidst decline. Without a changed strategy, working class conditions will be taken down with and by the system’s decline. $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ What the working class can do is move into the streets to stop “business as usual” until steps are taken to reverse the last 40 years’ redistribution of wealth. Workers must also stop endorsing and voting for candidates who do not serve their interests. Nothing would better show workers’ seriousness about reversing the last 40 years than building a new labor-based political party to change US politics. $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

Always a welcome end to my shift.

This video will make a fine addition to my thursday :)

I have been thinking about a thing which perhaps you somehow can answer(if so please do) Halting problem: Given Turing Machine M, you can not (generally) predict whether it will halt or not. Full-on determinism: Given state of the universe S, you can predict all future states. These two can't both be true, since if you can predict all future states, you can predict whether a machine M(assuming it can exist in/as part of the universe) will halt, since halting/not halting is one of the future states you can derive. Possible criticism I immediately came up with is: Turing machines can't be part of the universe, since they require an infinite tape to work with. Possible counter-criticism I immediately came up with is: Dark energy is an infinite source of (albeit useless) energy, thus could potentially be turned into an infinite source of matter, thus an infinite tape.

At 20:55 *how* was the castle doing the huge 180 degree turning circle, with the turning circle of 2500 AU (1.2 times the width of our solar system)? Not the electromagnetic tethers, I assume?

One thing also, I know it's a bit off topic considering this is mostly future speak but one thing we already know is some bacteria evolve/grow quite strongly in low g/zero g environments, there's a good possibility if something is 'fermenting' the entire ride through space it could have it's own novelty of flavors which would drive those prices even higher as far as commodity.

As long as immortality is achieved, I welcome the bright future of space travel.

I theorize that you can parallel to a degree normal seafaring trade with spacefaring trade if you can get similar shipment time between two points of locations.

Oh cool

Would these cyclers be going straight between a number of systems and circle back around in straight lines or in massive curves single circles that pass over two or more points as they travel along the path?

Hi Isaac, I have been watching your videos for a while now (roughly 6 months). I am curious, if economics were to change what do you think would replace paper money?

Realized when you referenced your interstellar highwasy episode ive been watching for over 3 years. Hard to believe. Feels like I found you a few months ago.

As for crude matter. Upload to such castles could probably be in the form of ion beams.

It does not make sense for me that the "castle"/cycler is speeding up and slowing down. Wouldn't it be more practically if cargo would do that? In case of crude matter it could easily decelarte and accelerate at higher g.

It isn't speeding up or slowing down, it is making a turn so that it is headed towards the next system on a giant loop of star systems. If there are two dozen systems in a loop the cycler would have to make an average of at least fifteen degrees of turn at each system.

While interstellar trade might be technically feasible I wonder if our social structures could ever be strong and stable enough to make it dependable. A break in the network due to societal problems at just one system could have disastrous consequences. The mind boggles at imagining an attempt to react and compensate for a some breakdown along the circuit while travelling 20%c. But, ah, never mind. Future humanity has a couple of centuries to sort it out. I'm sure they will if the money's right. Of one thing I am sure: Tramp freighters will be a lot more interesting at that point.

Imagine a small wire wheel turning at say 0.5c, enormous G forces would spllit it apart. But increase the radius, they become manageable. Size 10 billion miles radius, around the sun far beyond pluto, thus you have a way of catching a castle incoming at roaring speed. It can then be released later in any direction, including right back again at no energy loss. It is an energy bank, so it would be a project to get it up to speed with solar energy, but we do have a star for that. There would be ways to transfer locally in light shuttles off that carousel to smaller slower rings. Something for the 22nd century I suppose, but no well dressed star should be without one.

I'm a few days late to this video, but oh well. I recently finished "House of Suns" and this topic goes right along with that book.

Have you considered that interstellar trade might be vacilitated via a gift economy? I know this might sound silly from our modern perspective but historically gift economies have developed in areas where trading parties were widely dispersed and contact was scarce. That seems to fit with interstellar travel assuming that there is no ftl.

You just gave uber eats an idea.

Is there a blog or something where I can see the calculations written out?

A colony can build system-sized telescopes and gather data with somewhat more precision than that available elsewhere. Combining data from multiple colony's telescopes creates a telescope with light-year scale aperture. BTW: That means a culture that operates with century-scale planning. - Interstellar trade of materials or manufactured objects makes no sense. There is nothing that cannot be duplicated with local materials. So the thing of value would be the specifications enabling the duplication. That information can be via a photon beam.

Forgive me if I am misunderstanding something. Couldn't quantum entanglement give us a reason to take stuff between stars, and also be "instantaneous" communication?

Yeah teleportation is... No. We could make packets of entangled matter we could make some kind of quantum twitter. As every packet is sealed and only observed when it is necessary. This seems almost feasible to my shade tree quantum degree.
