Examples

  • A simple superposition is not possible, because the knowledge of the weight in the equation of every single factor is unknown to man.

  • There is no mystery as to how the photon can be in superposition in both space and time if 4D spacetime is considered really real.

  • Penrose had an answer to why large things don't appear in superposition (the more the mass, the faster to Objective Reduction (OR) due to gravitational energy), but he didn't have a ready answer for why observations caused OR.

  • If a cat's life was directly tied to a quantum effect in superposition, would the cat be both alive and dead at the same time?

  • The single electron at the top (in superposition of both spin up and spin down states) is measured, and reduces to a single classical state (e.g. spin down).

    A Third Choice (ID Hypothesis)

  • A simple way to understand this is that the simple meaning of the word superposition is the placement of one thing on top of another.

  • "In Schrodinger's famous thought experiment of the 1930s, a cat would be placed in a sealed box with a device containing atomic material.

    A Geiger counter was included to measure radiation if at some point an atom decayed. Should that happen, the Geiger counter would trigger the release of cyanide gas, which would kill the cat.

    The idea was that it was impossible to know whether or not the cat was alive or dead without opening the box and observing it, and that until that happened, both realities existed. This became known as superposition."

  • It warms my heart not only to be reminded by the CD&C of the mathematical term superpose, but to learn as well that there’s a French word spelled superposer.
