@@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. 🧑‍🌾

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.

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.

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 9 дней назад
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...

Is it possible to have a stellar mass 'rocky body'? meaning something approaching the weight of a star but instead of gas its mostly rock. 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? It does not seem to quite meet the requirements for a brown dwarf. any advice on this subject would be quite helpful.

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.

I have a few questions, maybe not really related to this topic. 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?

@MarsStarcruiser

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

Got any sources I could see that rule out the big rip?

@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

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

I am considering Planetary Bracelets for the colonization of my systems gas giants. As well as contemplating colonizing the White Dwarf 0.81 light years from my system.🤔

If we "need" gravity-agnostic drives to travel through the galaxy and beyond then would the weapons look the same? Alla Fermi Paradox if you can move a ship at or beyond light speed so can you move ordinance. What happens if a civilization flings a planet at another planet? If they 360 no scope is God pleased? These are the answer I want upon upon death.

God is *always* pleased by a 360 no scope.

At that speed, cherenkov radiation is your ordinance. Particles slowing down to sublight velocities will have to shed lots of photons to compensate, so you’d wake similar to sonic boom but cherenkov boom in space, cooking everything around you as you drive by😂 Edit: not to mention whatever the hell gravity waves would be doing to everything around you too
