The “delayed choice” modification, Chisholm explained, incorporated the use of entangled photons and mirrors to effectively “delay” the observer’s real-time choice of whether to observe…until after the light had revealed how it was going to act.

It somehow anticipated what choice the observer would make in the future…as if the universe already knew what would happen before it had happened.
