Propositions
1. Could the laws of nature be governed by higher (or, even infinite) derivative differential equations? 2. Nonlocality of the gravitational interaction might be a key ingredient to formulate a consistent theory
of quantum gravity.
3. Nonlocal interaction implies violation of microscopic causality which is one of the expected features of quantum space-time.
4. The existence of a minimal length at which nonlocal effects manifest might be crucial to prevent cosmological and black hole singularities.
5. Infinite derivative operators could be useful to enlarge the class of symmetries under which local Lagrangians are invariant.
6. Gravitational wave production from merging of compact objects can represent a promising experi-mental scenario to test nonlocal field theories.
7. Low-energy condensed matter systems are useful analogue models to capture the main features of nonlocality and test them in a laboratory.
