If jupiter has massive amounts hydrogen on it would droping a large amount of nukes on it cause it to burn? could we destroy earth if we shot nukes here?

Unfuckingreal. I say this with the utmost earnestness in my heart: I hope you die a horrifying painful excruciating death, preferably due to cancer over the span of a decade. I hope I never have to read anything written by you ever again. I hope you turn out to be infertile and that your entire bloodline comes to an end with you, you pathetic piece of excrement political traveller! I wish I could go back in time and shoot moot square between the eyes when he decided to reinstate /pol/. Fuck you and fuck all your acquaintances up to 2 hops away, in case your retardation propagated to them. Never post in my board again.

While you can't turn Jupiter into a star, it is not ruled out that you could turn Jupiter into a catastrophic thermonuclear bomb. The limitations to this was calculated at Lawrence Livermore in the 1970s, as a continuation of the work done to check to make sure Earth's oceans wouldn't ignite due to the deuterium content of water. Necessary Conditions for the Initiation and Propagation of Nuclear Detonation Waves in Plane Atmospheres by Weaver and Wood (https://web.archive.org/web/20190425004719/https://e-reports-ext.llnl.gov/pdf/177765.pdf)), couldn't rule out a self-sustaining ignition shock-wave in a planetary atmosphere at a deuterium concentration of more than 1 percent at ordinary liquid densities.

Although this makes the oceans safe, Jupiter is big, and it might have segregated a deuterium layer deep inside which has a high enough concentration to allow a self-sustaining nuclear ignition. Then if you drop a configuration of plutonium designed to detonate the deuterium by a nuclear explosion at the appropriate depth, you could get a detonation wave that ignites the entire deuterium layer within a very short time, the time it takes a shock wave to encircle Jupiter.

The energy output could convert a non-negligible fraction of the deuterium in Jupiter to 3He/tritium, and release enormous amount of energy. If 1 Earth mass of deuterium is ignited by the ignition shock wave, the energy release is 1038J, over a very short time, perhaps an hour or two and this is already 10,000 times the energy output of the Sun in a full year. The resulting explosion would destroy that part of the world facing Jupiter, and probably bake the rest. I don't lose sleep over this, though.

If there is a natural trigger for such an explosion, perhaps the collision of a rocky planet with a gas giant, one might experimentally observe such planetary mini-supernovas somewhere. This was suggested in section VIII of Weaver and Wood's paper.

Can we somehow get rid of Jupiter so it doesn't explode? Let's throw it into the Sun safely.

Have you heard of the sun? Way larger than jupiter. Lots more hydrogen. "Burning" all the time, nuclear fire infact.

Earth still intact

[Anonymous No.12501307]

>>12500884
Sorry, but I have to call BS on this
Jupiter attracts meteors like a damn hoe
If it can explode, why does it?

Hydrogen is nonflamable. Only way to gain energy out of it is through nuclear fusion and the only way to fuse atoms is via gravity
Or via implosion using a ring of conventional explosives.

Jupiter is too damn big for that and the hydrogen concentration is not suitable for self-sustaining chain reaction

Hydrogen has nothing to do with the proposed scenario in that post, at least not directly.

What they are really proposing is that an Earth-sized or bigger planet hits Jupiter (or any gas giant) and penetrates deep enough to hit a deuterium layer deep beneath the clouds, and the sudden influx of deuterium (and heavy other radioactive material) from the smaller planet could cause unstable fission in the gas giant's deuterium layer, causing a chain reaction that would unleash about 10000x the Sun's daily energy output in a matter of hours. The hydrogen in the gas giant's atmosphere wouldn't burn, it would basically turn into plasma due to the intense energy and heat of the reaction, but the hydrogen itself would not react beyond getting really really hot.

In any case this scenario is ridiculously unlikely because any planet that runs into Jupiter is going to get torn apart by gravity or Jupiter's atmosphere before it gets deep enough to hit a deuterium layer. The only possible scenario in which a planet has enough speed and kinetic energy to get that deep before a catastrophic destruction of the planet is some kind of rogue planet that's been slingshotted at incredible speed and happens to hit a gas giant on an insane hyperbolic trajectory out of the blue. And the chances of that happening (particularly when the local stars gravity is going to have a far greater affect on the rogue planet than the gas giants) is, well, astronomical to say the least.

Basically, it's POSSIBLE that an Earth-sized rogue planet hitting a gas giant at extremely high velocity could trigger an uncontrolled nuclear reaction with immense amounts of energy released, but it's ridiculously improbable and not something humans are every likely to observe.

Also wanted to add to my post;
No one is even REALLY sure if there is such a deuterium layer in gas giants in the first place. Extrapolating from how much there is on Earth there should be a roughly Earth-sized amount of deuterium inside Jupiter, but there isn't any way to observe that or to even know exactly how it would act under the insane heat and pressure of a gas giant. The truth is, we really only understand the top cloud layers of gas giants. We can makes lots of educated guesses about the interior based on atmospheric density readings and observations made with insane pressure/heat on Earth, but it's all guess work. Until someone figures out how to build a probe that could survive to a gas giants core we'll likely never know for sure.

[Anonymous No.12501377]

>>12501365
I am still eying you hard here, mate
Your entire post relies on a layer of deuterium near the core which may or may not exist
Deuterium maybe heavier than hydrogen but it is still lighter than a helium and I find it very unrealistic that a layer of it would just seat inside Jupiter completely unconcerned with the super storms

Also, fusing hydrogen does not care about how heat it gets. If it fuses in an uncontrolled environment, it would just expand and cool and no such a thing as nuclear reaction that you are thinking of.

>No one is even REALLY sure if there is such a deuterium layer in gas giants in the first place
You could have started your post with this statement instead of causing popsci retards to think that Jupiter is ticking time bomb

Also, there would never be a probe that could survive a gas giant but there will be probes that could extract data from its atmosphere about chemicals, fluid dynamics, and sound frequencies to give us an idea of it even have a core to begin with.

No need to dig shit

>>12501377
First off, see >>12501373
I addressed that, i'm not trying to claim that paper is the truth or anything, merely that it's within the realm of plausibility.

Secondly, as I posted, the hydrogen will not undergo any nuclear reaction, it will just get really fucking hot and expand. The only thing undergoing any kind of nuclear reaction in this scenario is the deuterium (and any other unstable radioactive material that happens to be in either celestial body but that will be a tiny fraction of a percentage of the proposed yield).

Basically, all i'm saying is it's POSSIBLE, not that it's certain or even just likely.

>>12501384
>gas giant probe
You're probably right, but who knows what humanity will one day discover? Maybe future humans will use some exotic matter manipulation to build something capable of surviving to the center of a gas giant? Someday our descendants might make BRAAAAP shitposts while chilling in the core of a gas giant.

[Anonymous No.12501398]

>>12501389
BAH!
Your statement is as probable as saying that a super comet flung at high speed hitting the earth would cause the Earth's core (which is high in thorium and uranium) to cause a nuclear fission reaction

Non zero plausibilities are the workshop of popsci retards

Stop doing that

[Anonymous No.12501415]

>>12501398
Those aren't comparable at all though. We are talking about magnitudes of difference in the total size of the reactive elements.

An asteroid made out or pure uranium hitting the Earth with enough force to penetrate to the core (which is ridiculous because the thing would have to be moving at a significant percentage of C for that to even be possible) wouldn't cause a nuclear reaction because there wouldn't be enough unstable fissile material interacting to cause a reaction, and any reaction that did occur would be relatively weak.

In contrast with the gas giant scenario we're talking about astronomically more fissile material interacting suddenly, and a rogue planet could actually plausibly reach the speed required to penetrate a gas giant to the core (in fact, it's actually speculated that something like that might be what knocked Uranus on it's side).

At any rate, this is all massive speculation and pointless debate about an event that is so unlikely as to be functionally impossible. All i'm saying is; it's not 100% IMPOSSIBLE, just massively unlikely in the extreme.

I just want you to stop promoting that highly misleading info.
Popsci retards thrive on like things that are mystifying, scary, and dangerous

Saying that Jupiter is a nuclear bomb just because it has a lot of unstable isotopes is one thing but Jesus Christ.
It skips a whole lot of steps to cause that

Like a layer of deuterium/tritium at good enough concentration
Heat source powerful enough to ignite it in a way that promotes implosion
And ignoring the extreme fluid dynamics that would prevent the plasma from expanding before reaching super critical state

Some consider Jupiter and Saturn and other 'gas giants' to be failed stars. Insufficient mass to create the pressure necessary to initiate fusion.

[Anonymous No.12501622]

>>12501569
Gas giants aren't even close to being failed stars. You would need like 80+ more Jupiters to get fusion going.

Brown dwarfs are actual failed stars.

You kidding?
They ARE used for hydrogen bombs and are a the primary ingredient for fusion reactors.

Hydrogen comes in 3 isotopes (extra/less neutrons)
Hydrogen which is 1 proton 0 neutron
Deuterium is hydrogen with 1 neutron
Tritium is 2 neutrons

Tritium is the best but it is super unstable.
