Schrödinger’s cat can be saved after all. Did we not know it?

    It seems new results contradict Danish physicist Niels Bohr’s established view — the quantum jumps are neither abrupt nor as random as previously thought.

    Yale physicists have published a paper in Nature
    “To catch and reverse a quantum jump mid-flight”.

    https://www.nature.com/articles/s41586-019-1287-z

    Authors say “In quantum physics, measurements can fundamentally yield discrete and random results. Emblematic of this feature is Bohr’s 1913 proposal of quantum jumps between two discrete energy levels of an atom1. Experimentally, quantum jumps were first observed in an atomic ion driven by a weak deterministic force while under strong continuous energy measurement. The times at which the discontinuous jump transitions occur are reputed to be fundamentally unpredictable. Despite the non-deterministic character of quantum physics, is it possible to know if a quantum jump is about to occur? Here we answer this question affirmatively: ....”.


    Yale News reports the findings, noting that since the quantum happenings can be controlled the Schrödinger’s cat can be saved after all.

    Physicists can predict the jumps of Schrödinger’s cat (and finally save it)

    (My note: Actually it is not the cat that jumps though. Report writer takes a little Liberty).

    The report says: Schrödinger’s cat is a well-known paradox used to illustrate the concept of superposition — the ability for two opposite states to exist simultaneously — and unpredictability in quantum physics. The idea is that a cat is placed in a sealed box with a radioactive source and a poison that will be triggered if an atom of the radioactive substance decays. The superposition theory of quantum physics suggests that until someone opens the box, the cat is both alive and dead, a superposition of states. Opening the box to observe the cat causes it to abruptly change its quantum state randomly, forcing it to be either dead or alive.

    The experiment, performed in the lab of Yale professor Michel Devoret and proposed by lead author Zlatko Minev, peers into the actual workings of a quantum jump for the first time. The results reveal a surprising finding that contradicts Danish physicist Niels Bohr’s established view — the jumps are neither abrupt nor as random as previously thought.
    ...

    We can thus control the fate of the cat after all. Did we not know it?

    And now the joke about a cat putting a physicist in a box takes on a new meaning

    When the box is closed, we are in the dark. Because we are in the dark, this allows speculation and debate to rule the day. The debate allows either state to be assumed possible, therefore, even contradictory theory is allowed. This black box approach is fundamental to statistics, which assumes all results have finite odds and therefore all states have odds that exist, simultaneously.

    Once you open the box, we move from the darkness of infinite speculation and tiny odds, to the light of tangible observation. Now both scenarios can no longer be true at the same time, since these are mutually exclusive. The statistical black box speculation approach never made sense in the first place, since it was imaginary and speculative. The observational result; open box tangible result; had always been determinant, one way or the other. The research team is showing, that which what assumed to be statistical, is now not so.

    This research has a connection to the biggest problem in Physics. This larger version of the Schrödinger’s cat paradox was pointed out by Einstein and is called relative reference. Relative reference means that there is no preferred reference, in the universe. Observation is relative to the observer. This is a variation of Schrödinger’s cat. This means mutually exclusive theory is allowable, since theoretical references are relative and therefore each can generate a statistical result, even if they are mutually exclusive.

    There is a solution to this black box darkness, that currently is the foundation of modern physics. It requires opening a black box. Einstein, unknowingly, gave the answer to the riddle, but nobody saw it, because statistics was ruling the day and the Einstein was muscled out by politics.

    Einstein said that the speed of light was the same in all references. This included references that were, otherwise, considered relative to each other. The speed of light was the one thing that was deterministic, even in all the relative references. Therefore, to upgrade Physics to the future, we need to make the speed of the light the common mathematical ground state, so we have a determinant foundation, that can be used by all the relative references. This allows everyone to start with an open box so we always know the state of Schrödinger’s cat.

    Currently, we assume zero is the slowest speed and that speed(velocity) can increase up to the speed of light. However, since reference is relative, we cannot accurately define a single universal velocity between zero and the speed of light, since this range is not the same in all references. But at the speed of light, suddenly, we all can agree. At that moment the universe is determinant and this becomes the scaffolding to unify theory.
