Never expected such a satisfying ending of DARK. With my meagre knowledge of Quantum mechanics, I can relate the main protagonists Jonas and Martha to electrons in an orbital. Like two electrons, according to Pauli's exclusion principle, can never have same set of four quantum numbers; Jonas and Martha (of same world) can never be united. The way Jonas from one world got connected to Martha from another world shows nothing but the advanced knowledge of Quantum entanglement of the writers, which, I personally feel, has uplifted the level of sci-fi series. Like in Quantum Entanglement, if we change any of the four quantum numbers of an electron in an orbital (containing paired electrons), the quantum number of another electron changes, this is how if anything is changed in Jonas's world, also procure changes in Martha's world, which is amazing.
Thanks Baran bo Odar and Jantje Friese. Truly a 'Masterpiece'.
