According to relativistic quantum field theories, particles are to be
understood, rather, as specific arrangements of the fields. Certain
arrangements of the fields, for instance, correspond to there being
14 particles in the universe, and certain other arrangements
correspond to there being 276 particles, and certain other
arrangements correspond to there being an infinite number of
particles, and certain other arrangements correspond to there being no
particles at all. And those last arrangements are referred to, in the
jargon of quantum field theories, for obvious reasons, as "vacuum"
states. Krauss seems to be thinking that these vacuum states amount to
the relativistic-quantum-field-theoretical version of there not being
any physical stuff at all. And he has an argument — or thinks he does
— that the laws of relativistic quantum field theories entail that
vacuum states are unstable. And that, in a nutshell, is the account he
proposes of why there should be something rather than nothing.
