Does Probability Come from Quantum Physics?

— Ever since Austrian scientist Erwin Schrodinger put his unfortunate cat in a box, his fellow physicists have been using something called quantum theory to explain and understand the nature of waves and particles.

But a new paper by physics professor Andreas Albrecht and graduate student Dan Phillips at the University of California, Davis, makes the case that these quantum fluctuations actually are responsible for the probability of all actions, with far-reaching implications for theories of the universe.

Quantum theory is a branch of theoretical physics that strives to understand and predict the properties and behavior of atoms and particles. Without it, we would not be able to build transistors and computers, for example. One aspect of the theory is that the precise properties of a particle are not determined until you observe them and “collapse the wave function” in physics parlance.

Schrodinger’s famous thought experiment extends this idea to our scale. A cat is trapped in a box with a vial of poison that is released when a radioactive atom randomly decays. You cannot tell if the cat is alive or dead without opening the box. Schrodinger argued that until you open the box and look inside, the cat is neither alive nor dead but in an indeterminate state….

    All of this speculation is simply an attempt to explain the process of creation.

    Seen in that context, i.e. the intent of a creative source, it all makes sense.

    Seen as some random accident only leads to dead ends.

    And dead souls.

    As for the cat nonsense, the laws of physics don’t change just because we aren’t aware of something at a given moment.

    Which came first; matter and physics or us?

    The Universe didn’t need us to exist in order to come into being. It was here already. The cat is simply in an unknown state but not in some other dimension until we open the box.
