Worldline Visualizer
Visualize the quantum mechanics setting of Apple TV+ drama 'Dark Matter'. Understand the structure of worldline branching, observer effect, and choice.
In the drama, protagonist Jason Dessen travels through countless parallel worlds via a device called 'The Box'. This diagram visualizes the structure of worldlines branching from the original world. Click to expand step by step and experience the spread of reachable worldlines.

The Role of Observation in Quantum Mechanics
In quantum mechanics, the act of observation itself determines reality. In the drama, this principle is depicted through the contrast between 'the chooser' and 'the non-chooser'.
Before observation, quantum systems hold multiple states simultaneously
Until observed, particles simultaneously hold multiple positions and states. This is the 'superposition principle' of quantum mechanics.
Observation determines one possibility as reality
Through the act of observation, the superposition state collapses into one determined state.
Other possibilities vanish, leaving only one reality
After observation, other possibilities vanish, and only the observed state remains as reality. This is 'wave function collapse'.
Can consciously choose worldlines. Functions as an observer and possesses the ability to determine the desired reality.
Tossed about by worldlines. As the observed, fate is determined by others' choices.
Describes the time evolution of quantum systems. In the drama, this represents how the protagonist exists in a superposition of multiple worldlines before observation.
Determines the probability distribution of observation results. The protagonist's consciousness and intention influence which worldline is "observed" and becomes reality.
Observation increases uncertainty in other physical quantities. In the drama, choosing one worldline creates countless variations of the protagonist in other worldlines.
