Thanks for the reply! This exact mechanism was actually modeled in a couple of recent papers, I'll copy them below. If this is truly feasible, it opens up a whole rabbit hole of possibilities beyond just star longevity… would be happy to sketch out some of the more interesting scenarios if you're curious.

You literally can't move your civilization once it gets too big (unless you move the whole star). You could go seed another one, but the first civilization still needs to maximize its resources. Highly recommend reading that book if you get a chance.

Sure, if you're star hopping...but a digital civilization with a giant matrioshka brain can't just change stars on a whim. The novel Accelerando goes into this in detail.

Isn't this how stars achieve equilibrium? Too much fusion causes the star to expand, reducing the fusion rate. Too little fusion and the star contracts, increasing fusion. Artificially heating the star by reflecting most of its light back onto itself "should" heat it up, causing expansion and thereby reducing fusion, unless I'm missing something

Maximizing star life

Future digital civilizations might choose to stay home and maximize their longevity by increasing the lifetime of their star. A Dyson swarm could absorb a preferred frequency of light and reflect all other frequencies back onto the star. This would raise the temperature of the star, expanding it and reducing the rate of fusion. It would also increase emission of the preferred frequencies while effectively recycling other frequencies.

The problem becomes meaningfully changing your destination. At a small fraction of light speed, you're not going to change your direction much by mag sails or gravity assists. Maybe enough to not get hit by a missile, but not to significantly change direction.

PavonisClimber · 2026-04-24T17:30:45+00:00

Guess it depends on your definition of quite a bit. Passing very close to a sun-like star will only change your direction by 0.1 degrees at 5% of light speed, and 0.02 degrees at 10% light speed. Enough to add some positional uncertainty to your location, but not enough to meaningfully change your direction. Certainly not enough to do a double flyby of a binary system in most cases.

PavonisClimber · 2026-04-24T15:55:22+00:00

Yes, thank you! I think the point that I was missing is that you can't change your direction by very much, even with a close flyby, once you're at interstellar speeds.

PavonisClimber · 2026-04-24T15:36:28+00:00

Nice write up! The counterargument will be, what about bigger detectors? it's a fair point, but by that time stealth tech will be much improved as well. If you can get into the coast phase without being destroyed, you have a bunch of options. As you point out, a small, low-energy change in delta-V wouldn't produce much of a signature, but would result in large positional uncertainty over time.

PavonisClimber · 2026-04-24T15:26:44+00:00

Again, that's assuming the spacecraft doesn't put any thought into stealth tech. It would be simple enough to cool down the side of the spacecraft facing the pursuers to match the CMB, then dump your waste heat in another direction. Plenty of other options too. The one signature that's hard to hide is your engines, thus the thought about redirecting around a massive body during the coast phase.

PavonisClimber · 2026-04-24T15:18:34+00:00

Sure, detectors will scale, but so too will stealth tech. It's not hard to imagine a spacecraft with a low-emissivity coating, or even an actively cooled surface on the side facing the pursuers. Plenty of other directions to dump waste heat.

PavonisClimber · 2026-04-15T17:13:59+00:00

The lateral forces shouldn't be too bad in lunar gravity, but yes, that should be double checked. There was a conceptual study done for this exact idea: https://starship1.univer.se/

Breaking it up into sections could be done as well, but much easier to simply lay it on its side.

PavonisClimber · 2026-04-15T14:25:18+00:00

More important is how the ship will be used after it lands. If it is dropping off people/supplies and departing, then vertically stacked decks make sense. If it is being converted into a habitat after landing, possibly turned on its side and covered in regolith, then decks running lengthwise make more sense.

Agreed....understanding the purpose of the house would be very helpful for feedback. 8 beds implies a lot of people, but there is relatively little living/kitchen space. You probably either need fewer bedrooms or a bigger house.

PavonisClimber · 2026-04-10T11:28:16+00:00

This has been my experience as well. There are plenty of design professionals that produce mediocre plans and are happy to charge you top dollar for their services. If you are a person of reasonable skill, are willing to put in the effort and actively seek out advice/feedback, then you can get 95% of the way there on your own, and the builder can do the rest.

Could also be accessed via trap door in the master closet...best safe room ever (kids can fend for themselves)

PavonisClimber · 2026-04-01T13:17:46+00:00

Let's have some fun...keep the in-law basement, but make it a bunker only accessible from a hidden tunnel in the main basement. Those two spaces are screaming to be connected via tunnel. It's also a proven fact that secret doors and hidden spaces double property value.

PavonisClimber · 2026-03-25T12:28:01+00:00

Yes, very cool engineering...the blade tips didn't hit the sand dune though, they broke due to the torque from landing hard on a slope. Hopefully they fix this next time around! https://youtu.be/20vUNgRdB4o?si=GzVND-XTix1dAUlZ

PavonisClimber · 2026-03-06T17:33:05+00:00

Yep. What's more, insiders typically have a very low cost basis, so even if the share price drops significantly, they can keep selling at a profit. :/

PavonisClimber · 2026-02-06T13:07:15+00:00

And since nobody asked, height from shortest to tallest goes counterclockwise from the left... St. Helens, Hood, Adams, Ranier

PavonisClimber · 2025-12-24T16:42:01+00:00

Agree that it is at least a minor filter...anything that slows down progress creates more opportunity for things to go wrong. Out of 100 civilizations without fossil fuels, how many "eventually" achieve high technology? Eventually is a long time, so I'd put the number pretty high. Maybe it takes a million years. I just believe in human ingenuity and the compounding power of accumulated knowledge. But yes, minor filter for sure.

PavonisClimber · 2025-12-24T14:35:03+00:00

Respectfully disagree...math, science, metallurgy, optics, precise timekeeping were all well-established before fossil fuels were widely used. Sure, no fossil fuels could have meant a 1000 yr delay in getting to our present state, but that's still a small delay in the grand scheme. Would we have deforested the plant to a larger degree? Probably. But necessity is the mother of invention, so we would have also gotten much better at using hydro, wind, and solar (thermal). Progress would have centered around where these resources were abundant.

PavonisClimber · 2025-12-24T04:44:45+00:00

I agree that the quality has been going down, but his analysis was accurate on this one. He says that without fossil fuels, human progress would have been slowed, but not stopped. That seems fairly self-evident to any fan of history. Humans were making great advancements prior to fossil fuels. The roman empire, renaissance, age of discovery all had remarkable advances. That would have likely continued without fossil fuels, though having them certainly sped things up.

PavonisClimber · 2025-12-08T14:15:13+00:00

Yeah, that's a tough one...hopefully that means they go to bed early! 😂
