The stacking is to ensure a sufficient density of neutrons to trigger the chain reaction.You were simply mistaught as a neutron chain reaction is not needed in either bombs or reactors or my rocket engine. The accelerated decay rate of impact and also from stacking radioactive atoms above critical mass is all that is needed to release large amount of energy.
Neutrons do not have an electric charge. The protons in teh Uranium nucleus do. The electromagnetic repulsion would keep the physical nuclei from colliding, but the electrically neutral neutron has no problem impacting the nucleus. Because the nucleus contains so many protons and neutrons it is easy to overcome the Strong Nuclear Force and initiate fission. That's why its the large elements that are used in fission. If your ideas were right you could fission simple atoms like oxygen or carbon, which you of course can't.I do find it very strange that you can even imagine a neutron stricking a uranium atom with some momentem causing it to split, but you find it unfathonable that hitting a radioactive meatal atom with antoer atom of the same momentum willl not cause it to split. Scientists do not know what an atom looks like or how it works.
As even this states, it is a simplification to describe the fissioning of a nucleus, but is not an accurate model of other nuclear processes.Originally posted by You linked to this
in nuclear physics, description of atomic nuclei formulated (1936) by Niels Bohr and used (1939) by him and John A. Wheeler to explain nuclear fission. According to the model, the nucleons (neutrons and protons) behave like the molecules in a drop of liquid. If given sufficient extra energy (as by the absorption of a neutron), the spherical nucleus may be distorted into a dumbbell shape and then split at the neck into two nearly equal fragments, releasing energy. Although inadequate to explain all nuclear phenomena, the theory underlying the model provides excellent estimates of average properties of nuclei.
Einstein was very influential in physics once the E=MC^2 equation was derived, but he himslef did not invent the atomic bomb. It was invented by a very large team of scientists working admittedly off the ideas of others, as well as their own ideas. Einstein never built an atom bomb, Einstein never test detonated an atom bomb; so even if he did draw up how one could work, he did not actually invent the thing. The guys who did the detailed math, designed and built the actual bombs, assembled The Gadget, and actually tested it are the guys who invented the atom bomb.The neutron atom model theory was not used in the invention of the atomic bomb as the inventor Einstein dismissed the theory as non scintific nonsense in 1913.* Even Neils Bohr, was unable to use the neutron theory to calculate critical mass until he worked backward from the correct value determined by Einstein's critical mass test and developed a liquid drop atom model.
Give me a link to ANY website, article, preprint, or study that shows verifiable experimental results that prove your ideas and I'll investigate it further. If you can show me experimental proof then I'll turn around completely and start writing my Congressman to fully find your rocket (I do write mine several times a month).
