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 😂
@@jsbrads1 I've often wondered if you could use the energy from stellar fusion to power more fusion to power more fusion for yet heavier elements than the star would normally produce before going supernova?
@@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. 🧑🌾
A far worse game than Alpha Centauri, somehow they can't seem to remake that. I think a relaunch is in order but the rights are probably owned by EA or something.
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.
Man someday I want to hear you chat about your Exalt game using pathfinder 2.0. Great episode again, wasn’t expecting the wire bracelet as the method but makes sense.
@Isaac Arthur I just wanted to say congratulations to you and your wife on the anniversary of your marriage as well as the successes that you and your family have achieved. Thank you for also inspiring me, as a disabled combat veteran (former Air Force Special Warfare SR/ SOWT Recon Specialist), to keep focused on the things that I can still do in life, as opposed to what I no longer can do, and keeping a realistic, yet positive view on things yet to come. You and your content truly mean a lot to me, despite not knowing you personally.
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.
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.
Depending on your age and the exact progress of life extension technology, you may well have been born at exactly the right time: early enough to know that you want to be on the first lots of asteroid mining vessels to get an economy crashing stock portfolio and your own habitat/generation ship.
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.
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.
Hypothetically speaking couldn't we use tidal forces by orbiting Brown Dwarves or if you're feeling brave. Another White Dwarf around the White Dwarf to keep it warm all but indefinitely. Using the heat to power our system that keep the orbits stable.
One day, I'd love a video that's just Isaac doing a stream-of-thought video, rambling about whatever topic comes to mind in the moment and going on endless tangents. I love listening to this channel in the background, at work and while playing video games.
@@martinwulf8253JMG is great but sometimes, with certain recurring guests, he could do with Issac metaphorically sat alongside going on tangents as a polite way of calling bullshit.
Note from humans of the future found floating in space- Hey we found this "useless" dwarf star your little planet is orbiting and decided to take it as a nightlight for our massive colony ship. Hope youre cool with that. Btw your planet smells like farts, you should do something about that. Maybe burn the methane to keep warm. Their response "humans really are just the worst.. lets go eat them."
There seems to be this obsession with getting gravity as earth-like as possible. And I'm over here just dying to live in low g so I can jump around like a maniac and have fun and play sports. I'd be pissed if I got up to a space hotel and found out that the accommodations were exactly 1G. Forget that I want something different lol
it's likely that most bedrooms would be set for 1g but most likely there certainly would be altered gravity [probably mostly lower gravity] spots that people could do stuff in.
Actually the JMC replicators were just vending machines with poor quality AI's (sometimes with speech impediments (so i guess they would be cool around here))
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.
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
On this fine Ar-Thursday, I ask what's you favorite pencil and paper RPG system? My current favorite is Savage Worlds. Still got a soft spot for RuneQuest also. As for DnD/Pathfinder, while my group does play them, I find they make figuring out the result of a combat excessively complex.
Hello Isaac Arthur. Hey, I have an idea that I give it to you to research, explore, expand and diversify. I love your videos. We humans need research about this. I know most or all your videos are about futurism. But you need to touch on the subject of what if we humans preserve their original birth bodies, breed them, improve them and extend their life and health through the future, thousands of years, millions, billions, trillions of years. And then having passive, pro-being, non intrusive technology, fertile biological treatments extensions and biological being assistive devices that protects and fertilizes the beings mind, body, soul and spirit. Because the human brain can survive different environments, realms and dimensions. An example is acid, lsd and mushroom trip which probably expands the mind forever and gives more IQ. The human brain is powerful. Probably there is a way for a small amount of brains to manage like octollions brains in several planets through ESP. Can the brain be multi task or multi processing? People have many things to do every day and they switch between tasks, they don't forget the other tasks. People save the states of all tasks in the brain. You can call these natural beings eons or neos humans. And then they would live in high technology environment while preserving and augmenting naturally their bodies and minds and surrounding environment nature. They could use an egg or a suit that keeps their bodies preserved. Hope you create a video about this. This is good research topics. We can't just be substituted by machines. Machines is not the next logical step. Machines have errors and limits. Now when a person takes hallucinogenic drugs they see new things to the mind and they still live. We would need like 10 distinct technologies to be sure what is the next logical step. We humans are natural. And we will never be obsolete. Thank You! Hope you find some insight from this. We need this kind of research in the universe and existence.
Humans are struggling to survive 200+ years since the industrial revolution. Yet you're debating how many billions of years are most suitable for developing rings around dead stars. Hmm. See you there?
I was on lsd many many years back and had the idea of simply moving earth further back in the solar system b4 the sun starts to expand then moving it in much closer after it retracts. This way a care taker species could try to keep earth perpetually going[might have to also restart the earths core or install electro magnetic sheilds when the core slows too much]
Personally ,I am surprised you didn't pull a variant of Niven's Smoke Ring series, after all if have earth like gravity nearly, and a centripetal path, maybe you could have a gas volume in in earth like pressure.
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?
I noticed that in a previous video. Apparently, it is hard to notice such mistakes during production and editing as the video window only makes up a small portion of the monitor.
is the thinner than air outer shell on a red giant actually hotter or colder than normal space? because it can convect heat, can it cool off more or does it just keep heating up?
Hold up it’s been 4 years since you got married??? How long have i been watching your channel... I remember when you announced that you where getting married. How time flies... 🤣🤣🤣
@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.
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 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.🤔
Awesome! I didn't even know 1/32nd of the information and I'm only 4 minutes in and am familiar with physics and cosmology. Can't wait to see where all this goes! With all the hard science that goes into your video's, I wouldn't be surprised if you had a degree in some form of engineering or mathematics because it would assume to me to be a good futurologist one would have to have a degree in something along those lines. I've been listening to you for close to 8-9 years and every subject I've watched you cover has been as informative as it has been entertaining which i could imagine it being difficult to pull off considering the subject matter. Keep up the amazing work! 💙⭐🌟✨💥🌌
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...
