Quantum Universe: Modal Logic Approach to Preferred Bases

[yanniru]

Here is a paper I do not understand. It is not even clear to me that it should be in the quantum physics forum as it concerns the foundations of the univrse.

It seems to be saying that the foundation of the universe is entirely waves (quantum physics) and that particles (classical physics)are an emergent feature of the universe.

I am of hope that someone on this forum understands the math in and the relevance of this paper. The link to the paper in arXiv.org and its Abstract are copied below:

Modal logic approach to preferred bases in the quantum universe
Authors: A. M. Lisewski
Comments: 51 pages; 1 eps-figure; accepted for publ. in Int. J. of Theo. Phys
We present a modal logic based approach to the endophysical quantum universe. In particular, we treat the problem of preferred bases and that of state reduction by employing an eclectic collection of relatively novel methods including Baltag's analytic non-wellfounded set theory, a modal logic interpretation of Dempster-Shafer theory, and results from the theory of isometric embeddings of discrete metrics. Two basic principles, the bisimulation principle and the principle of imperfection, are derived that permit us to conduct an inductive proof showing that a preferred basis emerges at each evolutionary stage of the quantum universe. These principles are understood as theoretical realizations of the paradigm according to which the physical universe is a simulation on a quantum computer and a second paradigm saying that physical degrees of freedom are a model of Poincar\'e's physical continuum. Several comments are given being related to evolutionary biology, to communication theory, and to quantum gravity.

Should this thread be moved to the quantum gravity & strings forum?

Should this thread be moved to the quantum gravity & strings forum?

I, for one, see no reason to consider moving it to the other forum.
You mean the String Brane LQG forum.
this paper is not about string or brane or Loop Quantum Gravity.

it does not even focus on quantum gravity per se, as far as I can see.

so IMHO you have put it in the right forum

First of all, thank you for sharing this paper with us. It is indeed a complex and technical topic, and it is understandable that you may have difficulty understanding it. The paper deals with the foundations of the universe, specifically the preferred bases in the quantum universe.

The main idea presented in the paper is that the universe is fundamentally composed of waves, as described by quantum physics, and that particles, as described by classical physics, are an emergent feature of the universe. This is in line with the current understanding in physics that matter and energy are ultimately made up of tiny quantum particles that behave as both waves and particles.

The author uses a combination of modal logic, non-wellfounded set theory, and other mathematical tools to present an argument for the existence of preferred bases in the quantum universe. These preferred bases are the fundamental building blocks of the universe, and the author argues that they emerge at each evolutionary stage of the universe.

It is important to note that this paper is a theoretical exploration and does not have any experimental evidence to support it. It is also not a widely accepted theory in the scientific community. However, it is a thought-provoking and interesting perspective on the nature of the universe.

As for the question of whether this discussion should be moved to the quantum gravity and strings forum, it ultimately depends on the focus and expertise of the members in that forum. This paper does touch upon the concept of quantum gravity, but it may also be relevant to the broader discussion on the foundations of the universe in the quantum physics forum. It would be best to consult with the moderators or members in both forums to determine the most appropriate place for this discussion.

In conclusion, while this paper may be challenging to understand, it presents an intriguing perspective on the foundations of the universe. It is always valuable to explore different ideas and theories, even if they may not be widely accepted. Thank you for sharing this paper with us and sparking a discussion on this topic.
