There are couple fun TH-cam videos about that, one is "powers of ten" which goes from 1m x 1m square to "pale blue dot" to "sky full of stars" to "no, those are galaxies, I mean clusters..." to "the light from known universe has not yet reached here". The other starts by comparing objects in our solar system and quickly gets to "that small dot beside the Sun is Earth". Then it starts showing actually large objects... Did I say "fun"? I meant to say "makes Lovecraft's Great Old Ones cower in fear". For antidote I recommend watching the Civilization game trailers.
Before watching the video: I watched a video from WhatDaMath saying that this is impossible because all the mass in the solar system (not including the sun itself) is not enough to form another star. Even if we put every planet (including Earth!)) comet, meteor etc. together it still wouldn't be enough. In particular, you would need the mass of over 76 jupiters. Ok, now let me watch the video on what insanity Isaac figured out as I'm sure he already knows this.
tbf most ideas about stellarizing Jupiter include stuff like dropping a micro black hole into it so it compresses into a tiny artificial star, rather than try and get it to ignite naturally, which it lacks the mass for, yeah.
not Jupiter per se, but there are some representations of Red Dwarf/Brown Dwarf companions like Luhman 16 or Barnard's Star replacing the sun here th-cam.com/video/3XgRyE7ELBo/w-d-xo.html

you need to gently nudge enough asteroids so that with some orbital mechanics they would hit that planet at the needed angle although that would also heat up that planet a fair bit

Can you make a video about an artificial magnetosphere for radiation protection of spaceship, station, Moon or Mars? Do we have a tech right now to build it at least on small scale?
I like the idea of stripping away the hydrogen envelope from Jupiter and then making use of the rocky planet left behind - a transformed Jupiter, but still a giant. Perhaps calling it . . . Zeus?
Meanwhile, the message they beam to Europa: ALL THESE WORLDS ARE YOURS EXCEPT EARTH ATTEMPT NO LANDINGS THERE ALSO WATCH OUT FOR ANYTHING THE EARTHERS ALREADY LANDED ON SORRY ABOUT THAT
The easiest way i was thinking we could do this is build a Dyson swarm esc series of mirrors around the sun and focus the light from the sun to a few light focusers (i understand that isnt a word) and have a relay of laser foucesrs and just use the light to heat Jupiter then build a small Dyson swarm around Jupiter's inner moons and boom one space heater
That’s very cool. How would you crunch down your tungsten megasphere without having Jupiter’s gravity just cause it to collapse into the planet though?
With the discovery of Brown dwalf stars the distinction between gas planets and stars gets very blured.are thing like Jupiter really planets or failed stars?as most star systems are binaries it would explain where the sun's companions are.
Please could you do a video on utopian outcomes for robotics? I love robots and grew up with 70's movies like silent running that showed them as friends and helpers, and then Terminator and Black Mirror came along and made people think the only possible outcome is DEATH TO HUMANS. I feel like robots could solve so many problems for us (for example I love the idea of on site robot medics that can emerge the moment an accident happens). To me, robots could be like a mechanical superman - ultra powerful and fast, but on our side and with a sense of morality and justice. But everyone seems sure they will all be skeletor. I think this holds us back.
Obviously building a tungsten shell around Jupiter would be quite challenging if possible at all. Operating at such high temperature is quite challenging too.
A little understood mechanism creates aurora on Jupiter, which the JUNO spacecraft is trying to help us understand. The working theory is that it's a result of magnetic fields produced by liquid metal hydrogen. I imagine the same mechanism is considerably more dramatic in brown dwarfs. So, Jupiter still produces visible light, just not a significant amount compared to a full fledged star.
What if we somehow managed to bring the jupiter moons into the habitable zone of our system or into an orbit which would make the climate more earth like ? Or into an orbit closer to earth ? Would the effort be worth it ? How could we do it ? How long would it take ? Would it be more feasable and make more sense than turning jupiter into a sun ?
Anyone here knows about the show, Terra Formars. In that story, humanity terraforms Mars by releasing moss and cockroaches. Apparently, Mars will start to warm up and absorb the sunlight because the surface is covered in dark colors. Cockroaches will eat the moss, expand their living area and the carcasses will make the moss grow in even thicker. 500 years later, Mars now has a stable atmosphere, large bodies of water (More like large lakes than seas) and moss as the only plant life. There's also the now Humanoid Cockroaches, but excluding that, would this method work in our world?
I have often wondered this my self what it would take to ignite Jupiter into a second sun so we could warm outer planets mind you size matters less while density is of far more importance. Next question would be if we could ignite jupiter as it is then how long could we hope its fusion fires to burn
Why do I get the feeling that in the future, the idea of using giant mirrors and shades in space will be looked on the way we now look back on the idea of shooting people into space in giant bullets?
I imagine that the mention of space police may be topical in a rather worrying fashion. Perhaps addressing ways in which ubiquitous computation and data processing may affect law in order such as was present in the Demarchy of Revelation Space would be an engaging point to discuss and critique the feasibility of.
This may be an indirect method of finding advanced aliens! If we can find a spectrum of a star that is very abnormal, and aligns with a theoretical spectrum of one of these designer stars... Perhaps we can even prove such a spectrum as being only from an artificial star.
Active support to resist compression makes sense to me. But in this episode you are talking about using active support to resist tension. Please explain how that works.
I don't think that one was thought through very much. The basic problem with the tungsten shell is that you'd probably have to mine Jupiter (or more likely the Sun) to get enough tungsten for it. Such little problems as how you make a hydrogen tight shell shrink from where it was supported on orbital rings to the point that it floats on the atmosphere are rather easy in comparison.
I think that instead of just turning Jupiter into a small red dwarf star. We take all the gas giants Jupiter, Saturn, Uranus and Neptune and crash them together to make a second sun. What effect would the gas giants colliding have on Earth and the inner solar system?
I was lost but by the time I was halfway through, I was loster. So loster that I could not find my way to the kitchen in my small NY house. The video was damn good though and that accent made it worthwhile.
I realise this is mostly an engineering proposition, but we don't know if there is life on Jupiter. There are so many sci-fi novels that posit that gas giants could contain 'gas bag' lifeforms. (I so want this to be true! 👍😊) I wonder how future humans would deal with the moral quandary such a discovery of life would present?
Use traditional active support to build the structure and then turn it off to start the compression process. Once you have begun straining the tensile strength of the shell structure use electromagnets to pull the shell in tighter. This is also active support.
When the Galileo spacecraft descended into Jupiter at the end of its mission, scientists considered it a possibility to ignite Jupiter into a second sun
@@ericgolightly8450 Yes I did. What does that have to with the fact that Jupiter gets hit with impacts far greater than Galileo's impact. Regularly doesn't have to mean every other week. It can mean every Thousand Years. Less than a decade earlier shoemaker-levy 9 impacted with at least an order of magnitude more power.
Wonderful episode! Was hoping you would have mentioned if we used the hypothetical primordial black hole, 5 to 15 earth masses, many propose is at our systems edge. Specifically how putting it in Jupiter's center could make a small black hole energized micro star. Thanks for these videos!
What would be the effect of significantly reducing Jupiter's mass on the orbits of the other planets? While the effect of Jupiter on the other planets is relatively small, it would seem that the effect of a significant reduction in its mass would be cumulative and may be large enough to cause problems over hundreds of thousands or millions of years. At the very least, it would release a significant number of Trojans which would make things interesting for the inner planets - though if you have technology advanced enough to mine Jupiter hoovering up the Jovian Trojans for construction materials would be simple.
Angl0sax0nknight Depends on how thick or thin you make the shell. Just use the radius of Jupiter in meters and the equation: V=4/3*pi*r^3-4/3*pi*(r-thickness of the shell you are putting around Jupiter)^3 Then to find the mass you do V*density of Tungsten converted to kg/m^3.
Do you think it would be possible to shotgun a neutron star (or just blasting enough artificial neutron matter, whichever's easier) into turning a large portion of Jupiter into deterium and tritum to instead lower the gravity pressure requirements of igniting a stable fusion reaction?
I don't understand how you'd be able to harvest net energy from compressing Jupiter (prior to the ignition of fusion). Since it's currently in equilibrium you'd have to expand energy to force it to compress, and that very energy you expend would be the source of the heating. Until you've added enough energy to the system to ignite fusion, theres no source of heat apart from your own activity.
I don't think you can use active support the way you suggested early in the video. Active support can replace compressive strength, but NOT tensile strength, which is what that shell would need in order to push down effectively. (To be precise, I believe active support can only achieve positive-semidefinite stress-energy tensors)
When calculating how long would it take to evaporate Jupiter's atmosphere, did you take into account the reduction of it's binding energy as it mass drops?
I wondered for a long time, what if there was a high power nuke dropped into jupiter. sure, that nuke needs to dive deep, where it can ignite the hydrogen. sure enough, I don't expect that this will ignite jupiter to continuously burn, but such a bomb should at least itnite the surrounding metallic hydrogen in that pressure wave. no idea, how long that pressurewave would go until it stops, but I think there is a nice chance that it will just go through all the planet and then stop. the disadvantage is, that this reaction will stop and that there needs to be another nuke dropped in. the advantage is however, that it is now tunable. want more power? drop more nukes. want to stop it? stop dropping nukes. and these nukes can be fairly basic. the fun part is, that thorium actually has a critcal mass, which is a bit below 3000kg for a perfect sphere. so I'd shape it in a way, that the rising pressure would deform it until it hits criticality, essentially detonating it without a trigger. and since hydrogen is an amazing neutron reflector and it's what jupiter is made of. the only problem is: that thing needs to get deep into jupiter, a few thousand km at least. so it needs to be surrounded by a good amount of heatshields. thorium oxide and carbon etc seems to be good, and adds 2 of the ingredients for the CNO-cycle in fusion. so probably that helps aswell.
I love astronomical numbers. "It's just 67 times the mass of Jupiter."
There are couple fun TH-cam videos about that, one is "powers of ten" which goes from 1m x 1m square to "pale blue dot" to "sky full of stars" to "no, those are galaxies, I mean clusters..." to "the light from known universe has not yet reached here".

Do you think it would be possible to shotgun a neutron star (or just blasting enough artificial neutron matter, whichever's easier) into turning a large portion of Jupiter into deterium and tritum to instead lower the gravity pressure requirements of igniting a stable fusion reaction?
Easy step-by step process of making Jupiter into a sun:
1) Take Jupiter
2) Add 98 more Jupiters
3) ???
4) Profit!
I love that you still sometimes use my music tracks... I'll make and send some more soon!
Such a poetic title.
Let's add 70 Jupiter masses to Jupiter! What could possibly go wrong?
I don't understand how you'd be able to harvest net energy from compressing Jupiter (prior to the ignition of fusion). Since it's currently in equilibrium you'd have to expand energy to force it to compress, and that very energy you expend would be the source of the heating. Until you've added enough energy to the system to ignite fusion, theres no source of heat apart from your own activity.
is your channel name a combination of Isaac Asimov and Arthur C Clark, if it is, well done
I don't think you can use active support the way you suggested early in the video. Active support can replace compressive strength, but NOT tensile strength, which is what that shell would need in order to push down effectively. (To be precise, I believe active support can only achieve positive-semidefinite stress-energy tensors)
Use magnetic attraction to pull tighter.
Some time in the future will we discover a Made in Andromeda stamp on a brown dwarf?
Isaac, bro, maybe its too cold where you live, but its already pretty hot here in Brazil. So i vote against more stars 😁.
LOL I was holding my screen upsidedown for quite awhile, and I didn't realizes until some text came up! There's no up or down in space. ;)
would it easier to turn a bunch of gas and comets from the oort cloud and kuiper belt by running it all into each other to make a second sun.
Hit it with a gas giant made of oxygen and light a match wooohoooo!
When calculating how long would it take to evaporate Jupiter's atmosphere, did you take into account the reduction of it's binding energy as it mass drops?
"Open the pod bay doors, HAL!"
I litterally googled this about a month ago, didn't really find anything though...
It's pretty obvious that all jupiter lacks is gas and mass to make it a brown dwarf and then a star.
I wondered for a long time, what if there was a high power nuke dropped into jupiter. sure, that nuke needs to dive deep, where it can ignite the hydrogen. sure enough, I don't expect that this will ignite jupiter to continuously burn, but such a bomb should at least itnite the surrounding metallic hydrogen in that pressure wave.
no idea, how long that pressurewave would go until it stops, but I think there is a nice chance that it will just go through all the planet and then stop.
the disadvantage is, that this reaction will stop and that there needs to be another nuke dropped in. the advantage is however, that it is now tunable. want more power? drop more nukes. want to stop it? stop dropping nukes.
and these nukes can be fairly basic. the fun part is, that thorium actually has a critcal mass, which is a bit below 3000kg for a perfect sphere. so I'd shape it in a way, that the rising pressure would deform it until it hits criticality, essentially detonating it without a trigger. and since hydrogen is an amazing neutron reflector and it's what jupiter is made of. the only problem is: that thing needs to get deep into jupiter, a few thousand km at least. so it needs to be surrounded by a good amount of heatshields. thorium oxide and carbon etc seems to be good, and adds 2 of the ingredients for the CNO-cycle in fusion. so probably that helps aswell.
