Measurement of Existence
This hypothetical device informs your quantum state within innumerable versions of our universe in the quantum state of the universe. The main idea is inspired by an equation, the measurement of existence from the relative quantum mechanics created by Everett.
Quantum state of the universe:
|Ψ UNIVERSE 〉 = ∑αi | Ψ WORLD i 〉
Measurement of the existence:
μi ≡ 〈 Ψ UNIVERSE ∣ Pi ∣ Ψ UNIVERSE 〉
The theory explains that there are many worlds existing in parallel in the Universe. Although all worlds are of the same physical size (this might not be true if we take quantum gravity into account), and in every world sentient beings feel as "real" as in any other world, in some sense some worlds are larger than others. I describe this property as the measure of existence of a world. "I" also have a measure of existence. It is the sum of measures of existence of all different worlds in which I exist; equally, it can be defined as the measure of existence of my perception world. Note that I do not experience directly the measure of my existence. In the system of the parallel universe, I feel the same weight, see the same brightness, etc. irrespectively of how tiny my measure of existence might be.
The Measurement of Existence is an interactive installation that incorporates both an animated graphic and sound. The device shows the simultaneity of innumerable states of a single electron, which forms the probability wave. As a viewer gets closer and observes the ambiguous state of the electron, the device is triggered to show the next stage of the viewer’s existence within the system of a parallel universe.
In the theories of quantum physics, the acts of observation and measurement play a critical role in creating our physical reality. When it is activated by the power of observation, it examines the sensory mechanism of measurement from the viewer, such as cognition and sight. Then, it visualizes a parallel state of the viewer’s universe, from clustered groups of galaxy to the solar system the earth inhabits.
