[SOLVED] Iron Fusion In Stars
If iron is said to be the last stage of fusion in stars, how is it that heavier elements are found on earth, where there seems to be less likely a chance for such fusion to occur? Where do these elements come from? Moreover, the half-life of a heavy element on the order of plutonium is only 24,000 years--how did such an element wind up on Earth in quantities that can be excavated? How is it that these elements were created?
