QR2.5.3 Accepting Quantum Reality

Quantum realism aims to reverse engineer the physical world based on quantum theory and computer science. It accepts as true the quantum theory statement that quantum waves can’t be seen directly because any attempt to do so gives a physical event, so quantum reality is literally unobservable not just by us but also by our measuring devices. Yet this doesn’t stop us reverse engineering it, as that is how we deduced quantum theory in the first place!

Some scientists fear that assuming the quantum world is real will lead to a God theory, one that “explains” by an all-powerful referent but doesn’t predict anything. In contrast, quantum processing is finite and the principles of processing are known. If reverse engineering leads to testable predictions, why not try it? For example, Chapter 4 predicts what current physics denies – that light can collide.

To reverse engineer physical reality one must accept that quantum theory is a reality description, so:

1. Quantum randomness really does come from outside physical reality.

2. Complex numbers work because electromagnetism really does rotate into another dimension.

3. Planck limits exist because our space and time really are digital.

4. Feynman’s sum over histories works because quantum entities really do take every path.

5. General relativity lets our space curve because it really is a surface.

In essence, quantum realism implies that the equations of physics aren’t imaginary or fictional but literally true. If the equations of quantum and relativity theory are good enough to use, aren’t they good enough to believe?

The calculus used throughout physics is an illustrative example. It began as a thought experiment, like quantum theory, that infinitesimals “in the limit” predict physical reality. Again like quantum theory, it worked brilliantly but physical realism decreed that it had to be “just theory”. Yet why not see calculus as a reality description? Why not conclude that reality actually does change in infinitesimal pixel steps and time progresses in indivisible cycles! Zeno’s paradoxes are resolved if we replace time in our equations with processing cycles. Calculus was only rejected as a description of reality because the continuity of physical reality is a canon of physics.

PS. For any calculus involving time, if one replaces dt by dp, a small number of processing cycles, then dp can indeed “tend to zero” as it cannot be less than one processing cycle.
