Which process is the only mechanism energetic enough to forge elements significantly heavier than iron, like gold and uranium?

Answer

The r-process (rapid neutron-capture process)

The incredible violence of a core-collapse supernova allows for the r-process, where nuclei are bombarded with neutrons so quickly that they capture many before decaying, leading to the creation of extremely heavy elements.
