@Efi Also, everything heavier than iron was made /during/ the time when the continuous explosion suddenly ramped up and exploded²
@Efi Though most things heavier than uranium that exist right now were made by some of the coalesced stardust attempting to understand the universe better by using other bits of coalesced stardust in very particular spacial arrangements and moving several bits of stardust into other bits of stardust at exceptionally high speeds but still slower than those involved in a core-collapse.
