There is no such thing as a "non-local event". An event is a point in spacetime. Go look at a relativity textbook.
Boing3000 said:All quantities are perfectly defined and Lorenz covariant.
You can define Lorentz covariant quantities that involve multiple events (multiple points in spacetime): for example, the invariant arc length along a particular spacelike curve. But these quantities do not describe "non-local events". They describe multiple events.

What experiments are you talking about?
Boing3000 said:Don't you agree that non-local is per definition something that happens once (thus an event) but across a wide range of place ?
No. See above and go look at a relativity textbook.
