[ExI] Does Space-Time Really Exist?

[Jason Resch]

I agree with what Ron Garrett explains here, which is that entanglement is
merely measurement: https://www.youtube.com/watch?v=dEaecUuEqfc

That is to say, they have the same mathematical properties in the theory.
Accordingly, the mystery of consistency as observed in entanglement when we
see consistency in measurements across space is no less (or more) than the
mystery of consistency across time when we measure the same thing more than
once.
