Pardon me if this is a naive question.

What is difference between saying space-time is not locally real, and saying it is not real?

The proposal that the universe is not locally real seems to imply that it is is non-locally real. But what does this mean?

There is a good discussion of a related question elsewhere on the forum, but I find the answers confusing. Physicists use words differently from philosophers, and on this topic I find the differences difficult to resolve.This may be because I'm being a bit dense, but I wonder whether the issue can be explained in a more general philosophical way, or at least in a way I can grasp.

Real, but not locally real, means that one can overcome the Bell argument (that there is nothing real being measured in a quantum measurement) by allowing information to be conveyed faster that the speed of light.
