What would it mean to "understand it" besides being
able to use the equations to make correct inferences?
It's an ostensible contradiction with relativity that

The reason touching an entangled system here is correlated
with it there is the system is the same in both regions of
space. Quantum mechanics is not really primarily about
causality in space or spacetime, but rather has a
representation in space and time.

Are you also baffled by the result of measuring the momentum of
one of two billard balls after their collision?
*Not if the interaction is treated classically since local realism is
assumed. But if it's treated quantum mechanically, the momenta don't
exist prior to the measurement. This implies instantaneous action at a

would have been baffling before Newton. Someone would have wondered,
