Coherence (2014): Superposition of a dinner party


Eight Friends meet up for a dinner party on the night a huge comet is supposed to be passing by the Earth. Things get stranger and stranger from there on.

James Ward Byrkit’s Coherence is a Sci-Fi film which tries to comprehend Quantum Physics. For beginners, let me tell you, quantum physics is inherently fuzzy.

A property of the particles in quantum universe is called Superposition. As per the theory, particles don’t exist in one state or the other, but in all of its possible states at once. I should be more clearer, I know. For example once you roll a die, according to quantum theory, the die exists in all its six states simultaneously.

When we observe a quantum object, we affect its behavior. Observation breaks an object’s superposition and the universe is literally duplicated, splitting into one universe for each possible outcome from the measurement. In case of our die… Once the observation is made, the universe splits into as many as the number of possible outcomes. In this case it is six, and within each universe the player has got one of the possible numbers.
