Why does quantum entanglement work?

[kakarot1905]

I understand how entangled systems behave [Roughly], but what causes them to do so?

 

[Demystifier]

I think it is safe to say that nobody knows the answer with certainty.

Certainty less than hbar.

3Cs:
conservation, covariance, correlation

because 1√-1. (positive spinlet up= negative spinlet down) therefore, everything becomes intertwined. kind of like gears.

maybe from the point of view of the entangled particles.. there is no space?

Compared to what? You have to have baseline to speak about cause.
Say if we take polarization entangled photons and compare them with photon pairs in product state then the cause is coherence and right phase between different polarization modes for interference to happen.
