Query: Bilocal theory and gravity I   With the aim of investigating the relation between gravity and non-locality
at the classical level, we study a bilocal scalar field model. Bilocality
introduces new (internal) degrees of freedom that seem to reproduce gravity. We
show that the equations of motion of the massless branch of the free bilocal
model match those of linearized gravity. We also discuss higher orders of
perturbation theory, where there is self-interaction in both gravity and the
bilocal field sectors.
