Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). The first thermonuclear ("hydrogen") bomb test released energy approximately equal to 10 million tons of TNT (42 PJ). The first test of a fission ("atomic") bomb released an amount of energy approximately equal to 20,000 tons of TNT (84 TJ). Both bomb types release large quantities of energy from relatively small amounts of matter. This article can also be found on the Huffington Post.A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions ( thermonuclear bomb), producing a nuclear explosion. Strangelove's absurdity before it puts an end to us. The trillion dollars saved can be used to strengthen US national security in many ways. Since the US and Russia currently have about 7000 each, thousands of which are on hair-trigger alert, the main effect of reducing their arsenals would not be to weaken deterrence but to reduce the risk of accidental war and incentivize nuclear non-proliferation. But wouldn't reducing US nuclear arsenals weaken US nuclear deterrence? No, even just a handful of nuclear weapons provide powerful deterrence, and all but two nuclear powers have decided that a few hundred nuclear weapons suffice. What should Barack Obama do? He should keep his election promise and take US nuclear missiles off hair-trigger alert, then cancel the planned trillion dollar nuclear weapons upgrade, and ratchet up international pressure on Russia to follow suit. This future nuclear war would almost certainly take more lives than nuclear deterrence ever saved - especially with nuclear winter and C-bombs. Even if the annual risk of global nuclear war is as low is 1%, we'll probably have one within a century and almost certainly within a few hundred years. Kennedy estimated the probability of the Cuban Missile Crisis escalating to war between 33% and 50%, and near-misses keep occurring regularly. The annual probability of accidental nuclear war is poorly known, but it certainly isn't zero: John F. So what should we do about this? Shouldn't we encourage the superpowers to keep their current nuclear arsenals forever, since their nuclear deterrent has arguably saved millions of lives by preventing superpower wars since 1945? No, nuclear deterrence isn't a viable long-term strategy unless the risk of accidental nuclear war can be reduced to zero. Strangelove himself explained in the movie: "the whole point of a Doomsday Machine is lost if you keep it a secret."
I felt relieved that my geeky nightmare was indeed nothing but a bad dream.Įxcept that life is imitating art: the other week, Russian state media "accidentally" leaked plans for a huge underwater drone that seems to contain a C-bomb.
General Douglas MacArthur did suggest dropping some small cobalt bombs on the Korean border in the 1950s to deter Chinese troops, his request was denied and, as far as we know, no C-bombs were ever built. Not that anyone in their right mind would ever do such a thing, I figured back when I first saw the film. There's almost no upper limit to how much cobalt and explosive power you can put in nukes that are buried for deterrence or transported by sea, and climate simulations have shown how hydrogen bombs can potentially lift fallout high enough to enshroud the globe, so if someone really wanted to risk the extinction of humanity, starting a C-bomb arms race is arguably one of the most promising strategies. The half-life of the radioactive cobalt produced is about 5 years, which is long enough to give the fallout plenty of time to settle before it decays and kills, but short enough to produce intense radiation for a lot longer than you'd last in a fallout shelter. When it explodes, it makes the cobalt radioactive and spreads it around the area or the globe, depending on the design. The idea is terrifyingly simple: just encase a really powerful H-bomb in massive amounts of cobalt. Now I unfortunately know better, and it seems like it Russia may be building it. Strangelove", I wasn't sure if it was physically possible. When I first heard about this doomsday device in Stanley Kubrik's dark nuclear satire "Dr. My worst one is the C-bomb, a hydrogen bomb surrounded by large amounts of cobalt. I must confess that, as a physics professor, some of my nightmares are extra geeky.
