SUMMARY

The discussion centers on the foundational aspects of measurement in the physical world, emphasizing that no physical parameter can be observed in isolation. It argues that every measurement relies on the interdependence of multiple parameters, suggesting a closed system of observable characteristics. The conversation highlights the inadequacy of current theories, including Relativity and Quantum Mechanics, in addressing the conditions necessary for measurement. Participants also explore the philosophical implications of defining terms within scientific theories, referencing concepts like functionalism and semantic holism.

PREREQUISITES
  • Understanding of basic physics concepts, including mass, charge, and magnetic fields.
  • Familiarity with measurement techniques, particularly in experimental physics.
  • Knowledge of philosophical concepts such as functionalism and semantic holism.
  • Awareness of the limitations of theoretical models in physics, especially regarding observable parameters.
NEXT STEPS
  • Research the role of magnetic fields in particle physics, specifically how they measure charge-to-momentum ratios.
  • Explore the implications of functionalism in scientific theories and its relation to measurement.
  • Investigate the concept of semantic holism and its impact on defining scientific terms.
  • Examine the philosophical questions surrounding the nature of observables and their existence in theoretical frameworks.
USEFUL FOR

Physicists, philosophers of science, and students interested in the foundational principles of measurement and the interrelation of physical parameters in theoretical models.

Clearly, gravity is a lightspeed interaction itself. But measurable changes in gravitational potential are due to the local motions of masses - so tied to their capacity to be at rest and unchanging.

I believe that's an assumption/hypothesis which hasn't any data to support it.

OK, the experimental verification is still in question (http://www.space.com/scienceastronomy/gravity_speed_030116.html ).

But it is a reasonable assumption in most eyes. And there is some data, even if it is being questioned.

Or are you offering an argument that it has some different value? I would be interested in the shape of that argument.

Can't...

the forum doesn't allow personal theories to be posted
