What prevents passing faster-than-light signaling through quantum
entanglement? Please explain for a dilettante like me could
understand.

I have the idea (maybe stupid, I'm not a physicist) that quantum
entanglement creates two connected worlds (including even the
researchers which research quantum entanglement) which in a sense
mirror each other with similar (or connected) events (that in the case
if we split a photon into two different places).
