It's not the half-life of U238 that you should be looking at stupid if you want to understand fission. It's how and why U235 fissions with slow neutrons, and how U238 can be made into U239 so it can also fission. You may not know this, but U238 also fissions very well, but with fast neutrons. Maybe you are the one who should learn some real science?
Big deal, I learned that in Jr High School. Also you left out the continuing stage of U239. U239 > Np239 +
b- > Pu239 +
b- It is Pu239 that is fissionable.
