I started writing Metal Stars after hearing Iron Stars from Isaac. It is about a civilization that uses fusion inside stars to create massive amounts of any element in a galaxy wide economy. Inspired by his video, but not really the same subject 😂

@@uncleanunicorn4571 best idea is to get as close to the weight as possible, if you want to make oxygen you want to start pre Red Giant. Also you need to change the star’s composition if you want it to make oxygen instead of carbon. Then you use star lifting satellites to prevent it from going Red Giant and maintain the right pressure to speed up the oxygen creation and you steal enough of the unwanted ingredients that would run away the reaction in the wrong direction. Basic fusion star farming. 🧑‍🌾

One problem with a glowing metal shell in a vacuum is that metal tends to sublime at elevated temperatures even if it isn't close to its melting point. Without an atmosphere we have nothing to counter that vapor pressure, which means that the degradation of the sphere will be that much more rapid. So the metal vapor will need to be continuously re-captured and re-applied to the shell not only on the outside but also on the inside.

With all the possibilties for statites, lagites, etc., I'd think that a civilization living "on" a white dwarf could use also use the remnant as the core of a stellar engine. If your civilization is going to be hanging around the galaxy for a few orbits, you might as well add steering to your space yacht! (or terraforming + colonization barge) It could be useful to add an inner side wall to a white dwarf bracelet. White dwarf stars generate cosmic rays, which in turn can result in cosmic ray spallation of cosmogenic, helium-3, lithium, beryllium and boron. The yield might be low, but protons absorbed by gasses like nitrogen, oxygen, and argon are protons that aren't hitting your infrastructure.

I think our notion of Habitable zone needs a major overhaul. White Dwarfs should impose significant tidal effects should they not? As a result, the Habitable zone feels like we need to start including elliptical orbits that would see the planet stretched and heated. We currently behave as though EM radiation is the only energy source life uses but even on Earth that is not true, and some believe life even started around a totally different energy source which tidal forces would provide.
@Cyberwar101
@Cyberwar101 11 күн бұрын
Yes, but tidal forces generate are only harvestable by life when it is simultaneously in an area of high vulcanism and not instable enough to destroy the environment. Also, it only seems to happen under the water. Solar is a vastly more usable and stable source, which is why life only uses geothermal where sunlight is non-existent. You can't run large complex ecologies on it without significant technological interference, such as using geothermal for powering lights.

Chandelier cities! That's what I instantly thought after hearing that when a white dwarf has the right spectrum a shell around it where the temperature is right would have about Earth gravity. I imagine a view out of the window with the sun somewhere below, lots of mirrors to reflect the sudlight the right way, shades to block it and lots of spaces with glass floors. Sadly guess such cities would probably have to be airtight. The outer side of the shell can have radiators and industrial facilities lit up by reflected sunlight. And yeah, quite high escape velocity around all this setup...

If such a thing existed I imagine it would look like some kind of dim star due to the residual heat of formation and radioactive elements ... but what would you call such a planet/star?

The mentioned temperatures are a bit misleading. A white dwarf with temperature of 40. 000k doesn't mean you need a star with a surface temperature of 40.000 k. The suns surface temperature is "only" 5778 k, but the core temperature is estimated to be around 10^7 k. Thus when the suns will become a white dwarf it will also at some point be a white dwarf (or something like that) with a surface temperature of 40.000 k. The HR-diagram is kinda misleading with surface temperature. It is the only temperature we can observe using blackbody spectra, but the fusion of a star happens within the core. When you look at the path a star takes around the HR-diagram after it leaves the main sequence. The surface temperature is a good indicator of how far you can look within the star (in other words how much of it shell it has shedded). It would be awesome to see a HR-diagram with core temperature instead of surface temperature.

Should the Universe continue to accelerate in its expansion, after how many years would the Big Rip kill off any civilization at the end of time? Would there be any civilizations left by then living on black hole batteries or would the Big Rip happen before the last black hole has evaporated and entropy had already claimed its victory?

No big rip anymore. Dark Energy Survey using hundreds of thousands of galaxies show both increase and decrease of expansion rate at different times. This implies mediation by unknown factor potentially driving and limiting expansion rate, rather than a perpetual acceleration. Even before though, the rip potential with old expansion assumptions were pretty vague though, like 30 billion years

@@MarsStarcruiser Wiki page on the Big Rip (last update December 2023) says 153 billion years at the earliest but also says that w has not been yet identified to be larger than -1. Got any sources I could see that rule out the big rip? Also what you're saying implies that w would change its value at the same time across the whole universe so whatever is acting on it would be doing it faster than the speed of causality or would imply that its actually a local parameter.

@@andreinicodim1622 Wo thats changed, but then again it’s been over a decade since I heard anything about it. Didn’t know anyone still took that hypothesis seriously since 2013-2019 dark energy survey. It’s been non-stop heat-death and then more recently cyclonic/crunch propositions after 2019.

@@andreinicodim1622 I don’t know if even the DES shows w change at same time universe wide. On their plot, the variance goes back and forth to indicate something uneven and their results were on averages

Humans only colonize places where they can get resources of some sort. We explore out of curiosity.

Ok so maybe a stupid question whats the chance, witha large gas giant being a failed star, that the shucked off outer layer of the oarent star increases mass and temperature enough to finish the process and ignite a planet like say jupiter into a full blown star?

@Isaac Arthur I have always wondered if you could somehow inject a white dwarf with fresh fuel, both hydrogen and helium, what would happen? Say an injection of 50% it's starting mass? ALSO, we have a gaming group too, and have an opening for one more person on our Sunday Hero Quest game. We are currently in the second story, but have had multiple characters killed by the Dirty Xargon. So we would be all starting out on the same basic footing. You are invited if you would like to play with us.

Too busy but thank you very sincerely :) you can inject new fuel but you have to triple it in or cause a nova
