Peace through practical, proved civil defence for credible war deterrence
  • Credible nuclear deterrence of invasions and conventional wars reduce the risk of large nuclear wars occurring through escalation of conventional wars. Contrary to irrational, pseudo-scientific propaganda, the number of nuclear weapons is smaller than the millions of conventional weapons used in large wars and the correct scaling shows that the overall effects are similar, not massively different as often claimed for political propaganda by enemies of peace. Furthermore, the greater time delay of effects from nuclear weapons over the damaged area increases the efficiency of cheap civil defence countermeasures, as compared to conventional weapons. In conclusion, credible nuclear deterrence of conventional war offers a beautiful opportunity to create a peaceful world, free from fear peddling, ranting dictators. The only oppositions you will meet will come from authoritarian obsessed fear peddling myth makers. If they can't tell the truth and face the facts, why listen to them? Please see our post on the need to deter not only direct threats from nuclear attacks but also conventional wars and invasions that can escalate into nuclear wars (as proved by the use of nuclear weapons in WWII, for example, after they were developed during the war itself and did not trigger or provoke the war), linked here, here, here, and here, here, here, and the true scaling law equivalence between a few thousand nuclear weapons and the several million tons of small conventional weapons in a non-nuclear world war as proved by our post summarising key points in Herman Kahn's much-abused call for credible deterrence, On Thermonuclear War, linked here. Peace comes through tested, proved and practical declassified countermeasures against the effects of nuclear weapons, chemical weapons and conventional weapons. Credible deterrence to end invasions and wars comes through simple, effective protection against invasions like low yield tactical weapons and walls, and civil defence against collateral damage. Peace comes through discussions of the facts as opposed to inaccurate, misleading lies of the "disarm or be annihilated" political dogma variety, which are designed to exploit fear to close down criticisms of errors in mainstream orthodoxy. In particular, please see the post linked here on EMP results from an actual Russian 300 kt test at 290 km altitude over unwarned civilian infrastructure in Kazakhstan on 22 October 1962, which caused no injuries or deaths whatsoever (contrary to all of Jeremy Corbyn and CND style lying propaganda that any use of nuclear weapons on civilians would automatically kill millions), but shut down the communications and power supply lines! This is not secret, but does not make newspaper headlines to debunk CND style dogmas on the alleged incredibility of nuclear deterrence.

    Big bang and supernova analogies ...

    ‘Dr Edward Teller remarked recently that the origin of the earth was somewhat like the explosion of the atomic bomb…’

    – Dr Harold C. Urey, The Planets: Their Origin and Development, Yale University Press, New Haven, 1952, p. ix.

    ‘It seems that similarities do exist between the processes of formation of single particles from nuclear explosions and formation of the solar system from the debris of a supernova explosion. We may be able to learn much more about the origin of the earth, by further investigating the process of radioactive fallout from the nuclear weapons tests.’

    – Dr P.K. Kuroda, ‘Radioactive Fallout in Astronomical Settings: Plutonium-244 in the Early Environment of the Solar System,’ Radionuclides in the Environment (Dr Edward C. Freiling, Symposium Chairman), Advances in Chemistry Series No. 93, American Chemical Society, Washington, D.C., 1970.

    The fractionation of fallout particles (which have a core of refractory material - i.e., high melting point material - surrounded by material with a lower melting point which has condensed at a later time in the fireball history), and their spherical nature, is similar in a way to planets. Obviously there are many differences.

    One of the main ones is that a typical fallout particle, 1 millimetre in diameter or smaller, is drawn into a spherical shape by electrical attractive forces called surface tension - similar to the reason why water forms droplets. But planets are held together by gravity, not surface tension. The main difference is that surface tension acts on the outer surface area which in turn causes internal compression.

    Gravity, however, is not due to a surface compression but instead is mediated through the void between fundamental particles in atoms by exchange radiation which does not recognise macroscopic surfaces, but only interacts with the subnuclear particles associated with the elementary units of mass. The radial contraction of the earth's radius by gravity, as predicted by general relativity, is 1.5 mm. [This contraction of distance hasn't been measured directly, but the corresponding contraction or rather 'dilation' of time has been accurately measured by atomic clocks which have been carried to various altitudes (where gravity is weaker) in aircraft. Spacetime tells us that where distance is contracted, so is time.]

    This contraction is not caused by a material pressure carried through the atoms of the earth, but is instead due to the gravity-causing exchange radiation of gravity which is carried through the void (nearly 100% of atomic volume is void). Hence the contraction is independent of the chemical nature of the earth. (Similarly, the contraction of moving bodies is caused by the same exchange radiation effect, and so is independent of the material's composition.)

    Since most of the mass of atoms is associated with the fields of gluons and virtual particles surrounding quarks, these are the gravity-affected parts of atoms, not the electrons or quarks themselves.

    The mass of a nucleon is typically 938 MeV, compared to just 0.511 MeV for an electron and 5 MeV for a quark. Hence the actual charges of matter aren't associated with much of the mass of material. Almost all the mass comes from the massive mediators of the strong force fields between quarks in nucleons, and between nucleons in nuclei heavier than hydrogen. (In the well-tested and empirically validated Standard Model, charges like fermions don't have mass at all; the entire mass is provided by a vacuum 'Higgs field'. The exact nature of the such a field is not predicted, although some constraints on its range of properties are evident.)

    Getting back to the topic at the top of this post, every type of force is nuclear in a broad sense. Gravity is basically nuclear because it depends on mass, which is concentrated in the exchange radiation between quarks in the nuclei of atoms. (If gravity was like electric charge, it would depend presumably on macroscopic surface area, which is not the case: in a charged metal sphere, the net electric charge involved in long range forces resides on the surface of the sphere not throughout its volume.) Electromagnetism in the form of the Yang Mills exchange-radiation U(1) symmetry has been unified with the weak nuclear force isospin symmetry SU(2) to produce the electroweak portion of the standard model, SU(2) x U(1), which has 4 gauge bosons that cause forces: the massive charged W+ and W- particles, the uncharged but massive Z particle, and the uncharged and light velocity (no 'rest mass') force causing photon.

    The reason why only one (the photon) of the four electroweak gauge bosons operates outside nuclear distances is simply that the other gauge bosons are attenuated by the vacuum at low energy. At high energy collisions (ie, near the charge core, assuming the particles have are able to hit hard enough to break through the vacuum shield) there is attenuation and the weak nucelar force is experienced.

    The quark is like a steel cored, rubber coated ball. Throw it gently (low energy) and all the interactions are soft, because the rubber shield is able to prevent the steel core from experiencing any direct interaction. But if you hit nuclear matter together very hard, the rubber is less effective at insulating the core and metallic interactions occur. It is really almost as simple as this; this is not a completely fraudulent analogy. Vacuum polarisation and shielding cause much of the 'rubber' type insulation. There is however some additional complexity which I've recently described on another blog, here, but as stated there it is not as complex as the supersymmetry formulation of the Standard Model.

    The strong nuclear force is described in the Standard Model by colour rotation symmetry, SU(3). It has 8 massive gluon mediators, twice as many as the electroweak force. The observed effective colour charge of quarks falls off with increasing collision energy, while the observed electromagnetic force increases with collision energy. These facts suggest that energy may be conserved between all types of gauge boson; the fall of the coupling for the strong force is accompanied by an increase in the coupling for the electromagnetic force.

    Conservation of energy of gauge bosons would suggest that when the polarised vacuum is completely broken down (at short ranges/high energies) and the electromagnetic force is maximised, the strong nuclear force will have fallen to the same value (not less than that value). Hence, including conservation of energy for the sum of gauge bosons of the fields automatically does what SUSY (supersymmetry) sets out to do, but instead of inventing unobserved imaginary superpartners like SUSY, we are utilising including a well-established physical principle (conservation of mass-energy) to do the same job.

    Of the four usually distinguished elementary forces of the universe (the strong nuclear, weak nuclear, electromagnetic and gravitational), some 50% at first glance appear to be nuclear in origin (i.e., the strong and the weak forces). However, as we have shown, electromagnetism has been unified with electromagnetism - and this electroweak unification predicted the masses of the W+, W-, and Z massive weak gauge bosons discovered at CERN in 1983, so it is hard real science. Hence on this basis there are three fundamental force categories (electroweak, strong, and gravity) of which near 67% are nuclear (electroweak ad strong). When you include the fact that gravity depends essentially on the nuclear mass between quarks as discussed above, you then see that 100% of the fundamental forces of the universe are intimately nuclear in origin.

    Back to the nuclear weapons and supernova analogy. Successive neutron captures in the explosion create very heavy elements like uranium which make the Earth radioactive today. See the previous post on this blog for the evidence for the 15 natural nuclear reactors in Gabon which occurred on Earth 1.7 billion years ago emitting 100 kW for 150 million years, when the ratio of U-235 to U-238 in uranium was higher than today (U-235 has the shorter half-life), and evidence of how nature contained the vast amount of intensely radioactive fission products for two billion years in perfect safety without any fancy concrete domes or expensive burial schemes!

    In addition to the shell structure magic numbers, it is supposedly impossible to get to element number 137 for theoretical reasons: the short range attractive strong force between nucleons will be exactly balanced by the long-range electromagnetic repulsion of 137 protons!

    This assumes that the strong force coupling for inter-nucleon forces is indeed exactly 137. The whole reason for radioactivity of heavy elements is linked to the increasing difficulty the strong force has in offsetting electromagnetism as you get towards 137 protons, accounting for the shorter half-lives. So here is a derivation of the 137 number in the context of strong nuclear force mediated by pions:

    Heisenberg’s uncertainty says p*d = h/(2.Pi), if p is uncertainty in momentum, d is uncertainty in distance.

    This comes from the resolving power of Heisenberg’s imaginary gamma ray microscope, and is usually written as a minimum (instead of with “=” as above), since there will be other sources of uncertainty in the measurement process. The factor of 2 would be a factor of 4 if we consider the uncertainty in one direction about the expected position (because the uncertainty applies to both directions, it becomes a factor of 2 here).

    For light wave momentum p = mc, pd = (mc)(ct) = Et where E is uncertainty in energy (E=mc^2), and t is uncertainty in time. OK, we are dealing with massive pions, not light, but this is close enough since they are relativistic:

    Et = h/(2*Pi)

    t = d/c = h/(2*Pi*E)

    E = hc/(2*Pi*d).

    Hence we have related distance to energy: this result is the formula used even in popular texts used to show that a 80 GeV energy W+/- gauge boson will have a range of 10^-17 m. So it’s OK to do this (ie, it is OK to take uncertainties of distance and energy to be real energy and range of gauge bosons which cause fundamental forces).

    Now, the work equation E = F*d (a vector equation: “work is product of force and the distance acted against the force in the direction of the force”), where again E is uncertainty in energy and d is uncertainty in distance, implies:

    E = hc/(2*Pi*d) = Fd

    F = hc/(2*Pi*d^2)

    Notice the inverse square law resulting here!

    This force is 137.036 times higher than Coulomb’s law for unit fundamental charges! This is the usual value often given for the ratio between the strong nuclear force and the electromagnetic force (I’m aware the QCD inter quark gluon-mediated force takes different and often smaller values than 137 times the electromagnetism force).

    I first read this amazing 137 factor in nuclear stability (limiting the number of elements to a theoretical maximum of below 137) in Glenn Seaborg’s article ‘Elements beyond 100′ (in the Annual Review of Nuclear Science, v18, 1968 by accident after getting the volume to read Harold Brode’s article - which was next after Seaborg’s - entitled ‘Review of Nuclear Weapons Effects’).

    I just love the fact that elements 99-100 (Einsteinium and Fermium) were discovered in the fallout of the first Teller-type H-bomb test at Eniwetok Atoll in 1952, formed by successive neutron captures in the U-238 pusher, which was within a 25-cm thick steel outer case according to some reports. Many of the neutrons must have been trapped inside the bomb. (Theodore Taylor said that the density of neutrons inside the bomb reached the density of water!)
