Quantum Gravity and Mereology: Not So Simple

Abstract A number of philosophers have argued in favour extended simples on the grounds that they are needed by fundamental physics. The arguments typically appeal to theories quantum gravity. To date, argument has ignored fact very existence spacetime is put under pressure We thus consider case for context different views spacetime. show based physics far more complex than been previously thought. present and then map this complexity, order a much textured picture simples.
