"the idea that gravity is a collective effect — not a fundamental force, but the outcome of swarm behavior on a finer scale — still compels physicists."

( #Physicsky #PhysicsSky no idea which of these works better )

*another big ol' rip*

The Big Bang precedes everything, and at that moment *everything* is local. All interactions are causally downstream and are thus also also local. Any perceived locality violation is a failure of framing
