thank you! one day I'll understand this stuff - I skipped the qft elective at uni, but I'm trying to learn more now.

  'The standard model' also doesn't include gravity. And we do have pretty good theories about gravity. So it's definitely not the 'sum total of human knowledge'.

    Does particle physics include gravity now?

      Sorry, I missed that. But yes in a sense: we do know that particles are subject to gravity. So that is part of 'the sum total of human knowledge of particle physics.'
