Essay Abstract

In this essay, I consider the anthropic solvability principle: the idea that solvability selects the forms of matter that direct our attention. Solvability is the condition when measurement and theory of a system reconcile in a consistent interpretation. The notion of solvability mediates between the physical properties of the system and the mathematical properties of the model we use to describe it. As with uncertainty and uncomputability, taking solvability---and unsolvability---seriously requires us to confront the role of subjectivity in physics. The reward is a renewed appreciation for the contingent and particular that emerge at the ragged edge of chaos and integrability.

"Why does a measly 5% of normal matter and energy continue to dominate our attention over the formless, dark majority?" I think that the answer to the previous question is that many astrophysicists are confused because they fail to realize that Milgrom is the Kepler of contemporary cosmology.

Why do Kroupa, McGaugh, Sanders, Scarpa, and others think that MOND makes many correct empirical predictions (that seem to contradict Newtonian-Einsteinian gravitational theory)?

Greetings Professor Nathan Harshman:

I agree with your notations of bias regarding dark energy as noted:

"Meanwhile, dark matter and dark energy remain unsolved problems; they persist as formless gaps in the scales of the universe, shadowed by the bias of our attention."

That bias of attention is based on decades of unconnected discoveries combined with many mathematical assumptions made at the beginning of the 20th century.

It is currently proposed that any evidence describing the Big Bang is beyond science's reach and yet this essay of mine entered January 18th Common 3D Physics Depicts Universe Emerging From Chaos presents a plausible explanation with plenty of current replicable evidence viewed and connected without bias. Check it out.

Dear Nathan I agree that solvability is an essential factor. However, in my case, I think the solvability came in the creation of the universe and its contents. In my essay I describe a self creating process that began in total chaos and progressed to the ordered universe. In the self creation from chaos, the processing had to solve all of the problems it encountered in its journey. The first one was big - how to overcome entropy. It also had to learn how to successful create everything needed to progress in its journey. You may enjoy the essay to get another perspective on solvability. John Crowell

Dear Prof Nathan,

Search for dark energy and dark matter continued for almost half decade in vain. May be you can just have a look at my Dynamic Universe model's ethical and scientific philosophy just for a change. You may not consider it, but just have a visit to my essay "A properly deciding, Computing and Predicting new theory's Philosophy"

I was working on that model for the last 40 years or so under the guidance of maa Vak. This model gave many realised predictions and solved many unsolved problems in Cosmology.

Best Regards

Dear Nathan,

I agree with your point of the bias. However, this is not directly related to the unsolvebility. Is this logical connection between the bias viewpoint theory and unsolvable of the nature? As also pointed out in my essay, theory is always to be better understanding of the nature. What do you think?

Best wishes,

Dear Prof. Harshman,

Outstanding essay!

Thank you for reminding us that since physicists are human, human biases will be reflected in physics as well.

I would like to point out one aspect that you did not address, the effect of confirmation bias on selection and interpretation of experiments. This bias can be particularly strong if there are large amounts of money involved. This can corrupt the system even while most individuals feel that they are honest and objective.

In my own essay, "The Uncertain Future of Physics and Computing", I point out that the developing technology of quantum computing provides the first significant application of quantum entanglement, and therefore provides a major test of quantum foundations. But the experimental measurements thus far in quantum computing have been designed to confirm the orthodox theory, not to test it. There are billions of dollars being invested in this; no one wants to admit the possibility of failure.

I predict that the entire technology of quantum computing will fail catastrophically within a few years. This may provide an opportunity for a reexamination of the foundations of quantum mechanics.

Dear Nathan,

A most interesting essay. I suggest that solvability may be advanced if we concentrated more on structure and less on probability. In other words the unreasonable effectiveness of Quantum Theory is detracting from efforts at probing deeper and analysing structure, both at the atomic and sub-atomic levels.

I too, in many talks, use both that video on scale as well as the static slides by the ? brothers (it's late in Oz). I think I managed to span some 60 order of magnitude, which speaks highly of our technology.

My particle theory, which I do not discuss in my essay on the 3 Un's, is a reductionist preon theory that actually works! I can reduce the number of needed Quantum numbers down to 3 and still have more predictive power than the Standard Model.

Good Luck
