Quantum mechanics teaches us that reality isn't.

Electrons are both particle and wave, or neither, depending on how one looks at it. There's no reason to assume that "reality" is any more real than that.

"rest of the universe" is the space-time area that falls outside of the light cone of the event. Relativity tells us that the event is irrelevant to those space-time points since information cannot travel faster than light.

The picture only changes when you bring into play the quantum-scale time hysteresis loops that some physisists are currently theoreticising about...
