The earliest description of the two suns is "2010, Threatening the Sun God", which says that the gravitational collapse generated by an ancient stele brought Jupiter's core to a temperature sufficient to ignite hydrogen, so Jupiter became the second sun in the solar system! Star Wars' Star Wars Starwalker Luke's home planet Tatooine also has two suns!
The Twin Sunsets are very beautiful, and of course the temptation is also very tempting for the solar system where there is a gaseous planet in reality! So can we theoretically ignite Jupiter with the explosion of a hydrogen bomb? Let's discuss it briefly.
First, the secret of star burning
In fact, before discussing whether a hydrogen bomb can ignite Jupiter, we must first understand the difference between an atomic bomb and a hydrogen bomb, and what kind of way the star burns!
Above the uranium atomic bomb nuclear charge u235 (uranium 235) chain reaction principle, a hot neutron hit the u235 nucleus after cracking into ba56 and kr36, please note that the proton number of the two after the split 56 + 36 = 92 has not changed, but the number of neutrons 144 + 89 = 233, compared with 235 is not less than 2? So this extra neutron will run out and hit the next u235 nucleus, continuing the process, and keep circulating until all the u235 nuclei are struck and split! The only key to this problem is that the u235 block is large enough, because the nucleus is so small that the neutron can guarantee that it can hit the next nucleus before flying out of the uranium block is the critical mass! Therefore, theoretically, once the chain reaction begins, it will be an irreversible state, unless there is a substance that can absorb thermal neutrons, and this is how the fission rate is controlled in nuclear reactors!
The picture above is the process of tritium-tritium fusion reaction in a hydrogen bomb, two neutrons and a proton of tritium and a neutron and a proton of deuterium combined into two neutrons and two protons of helium nucleus, releasing a surplus neutron, and at the same time releasing a lot of energy at the same time!
Have you found that whether it is fission or fusion, the total number of neutrons and protons has not changed, so where does the huge amount of energy come from? That's because the total mass of the nucleons that make up the new nucleus is reduced, and this mass reduction comes from a change in the interquark-acting force that makes up the nucleus!
So how do stars burn inside?
The above figure is a schematic diagram of the reaction between the solar core proton and the proton, and the tritium-deuterium reaction in the hydrogen bomb is different in that the solar core first has to fuse two hydrogen atoms, deuterium (only one proton), into a proton and a neutron of deuterium, and then from deuterium and another helium to helium three (the helium tritium on the moon comes from the sun), of course, there is a possibility that two helium trimerizations become stable helium four.
Of the three isotopes of hydrogen, most of them are deuterium in the universe, with very small amounts of deuterium, and in nature, tritium is extremely small! The tritium in the general hydrogen bomb is produced by neutron bombardment lithium!
Can a hydrogen bomb explosion ignite Jupiter?
We have already learned about the fusion of atomic bombs, hydrogen bombs and stellar cores above, if Jupiter is composed of a super u235 material, then it is obvious that both atomic bombs and hydrogen bombs can easily detonate Jupiter! But Jupiter is a gaseous planet, made up of 75% hydrogen and 25% helium, and of course it has a rocky core, which is only very small in proportion! If Jupiter is to burn, hydrogen must be made to fuse, and it must start with the earliest condensation of deuterium into deuterium!
But there is a very interesting fact that must be reminded that from deuterium to deuterium, a proton must absorb a huge amount of energy and then release an e+ and a neutrino to become a neutron, the process is very slow, the average time is as high as 109 years!
The whole process of the hydrogen bomb from detonation to the completion of the complete reaction is only seconds, and the time of 109 years is not to kill the hydrogen bomb!
Of course, there is another way, that is, deuterium fusion, which is relatively low compared to deuterium-krypton fusion
The deuterium nucleus has a neutron and a proton, which carries less charge, the Coulomb repulsion force is relatively small when the two deuterium nuclei are combined, the energy required for fusion is relatively low, and the average binding energy only needs 1.11 mev. Deuterium nuclei can continue to fuse at temperatures lasting 100 million degrees:
d+d→h+t+4mev d+d→n+3he+3.3mev
You can also use an atomic bomb of uranium-235 or plutonium-239 to detonate as a trigger! But this is still difficult to face the fusion of the deuterium element in Jupiter!
1, the content of deuterium in hydrogen is only .02%, that is, two parts per thousand!
2, the fusion reaction of deuterium can not be chain reaction, it is necessary to continue to maintain high temperature and high pressure during the reaction!
Simply put, this high temperature and high pressure environment must be maintained all the time, so the design requirement of the hydrogen bomb is to do everything possible to keep this ultra-high temperature and ultra high pressure a little longer, so that there is enough time for more deuterium to participate in fusion!
So from this point of view, it seems like some kind of flame retardant material, you use a lighter to ignite, then it can still burn, but once the fire source is removed, it is immediately extinguished, all to ignite Jupiter, this difficulty is not generally big!
How did the stars of the universe ignite?
Gravitational collapse is the only way to ignite stellar nuclear fusion, theoretically, just need to continuously increase the mass of the celestial body, then it will one day reach the standard of deuterium-deuterium fusion, for Jupiter, about 13 times the mass itself, of course, Jupiter has no chance, because Jupiter is 2.5 times the total mass of other planets in the entire solar system! But that's just up to the standard of a brown dwarf! To reach the threshold of stars - the red dwarf standard requires at least 80-100 times the mass of Jupiter!
So the hydrogen bomb doesn't ignite Jupiter!
Like please give a thumbs up, please pay attention, thank you!
