Webb14 apr. 2024 · The anihillation operator applied to the vacuum, however, yields zero. Zero in this case is the null set - it stands, quite literally, for no physical state in the Universe. The important point is that it is not possible to act on zero with a creation operator to create something; creation operators only act on the vacuum which is empty but not zero.
