Episode notes

Nuclear fusion is the underlying process that powers the universe. It fuses together or brings together two different elements. Underlying what this means is that you change the nuclear structure. This rearrangement through equals MC squared releases large amounts of energy. So fusion is literally the reason life is viable in the universe.
