- I do not understand what he is talking about. Can anyone explain it?
- Correcting the typos is the sentence:
- fragment "the delay must be as long as the time it takes light to travel
- from each polarizer to its local detector..." Even if this is what
- Budnik means it makes no sense to me.

- The key point is that the space-time interval between both measurements
- of both photons in the same pair makes no difference to the observed
- nonlocal correlation of spins predicted by standard quantum mechanics.
- That is the key new idea - the irrelevance of metric and the deeper
- breakdown of causality it demands.
