If we hadn ;t figured that out, we never would have learned how nuclear fusion works.

Here why.Fission bombs, as their name suggests, work by splitting unstable radioactive atoms and setting off a nuclear chain reaction that releases enormous amounts of destructive energy instantaneously. In the case of ugg mini Little Boy, the bomb the U.S. dropped on Hiroshima near the end of World War II in 1945, fission was achieved by firing what amounted to a bullet of uranium 235 into a larger sphere of the same material. The nuclei in some of the atoms in the target mass absorbed neutrons from the incoming projectile. This caused them to split into smaller atoms
