Physics and Potentiality
Possibilities are closely related to but different from potentials, like voltages or gravitational potentials or those corresponding to the other physical forces. Physical laws aren't in any particular directions, they are both the processes and the memories scientifically found by empirical research of physical matters and energies, through measurements in our universe, or perhaps possibly new universes, separate universes, or produced universes. There is a lot to learn to understand physics, such as the fundamental interactions and forces, which go together. There's strong and weak, which bind together atomic nuclei, some of the smallest stuff, but have very limited range; gravity, which binds together some of the largest stuff and has supposedly infinite range, and electromagnetism, which binds together things at many ranges, and has very unique mechanisms because of the attractive/repulsive force of electrical charge being related to the torquing/rotating force of magnetic forces. A quick way to remember it is: things can have electrical charges, like electrons and protons, or not (neutrons), and magnetic fields are generated by the motion of electrical charges. Rotational motion and spin are closely related to these, although I'm not sure about how the spin of individual particles is related to the spin of conglomerates like an atom or astronomical object. Don't spin yourself too fast+long or you'll get dizzy.
What is an interaction? What is a field? What is a force? I'll get to that. These 3 concepts are very closely related to each other and to the process of measurement/observation, which is important to quantum mechanical uncertainty. I believe measurement/observation is directly related to interaction, as if interaction itself produces an entanglement of the underlying states of quantum systems. Even though hidden-variable theories of quantum mechanical uncertainty are currently not believed by scientists to be possible, without violating other principles such as locality, these entanglements appear to produce coherency out of what may be incoherent wave functions that determine-indeterminately the states and changes of quantum systems. If there is some wave system underlying this universe, the uncertainty may be a matter of unavoidable perspective as it relates to fourier transforms. Regardless of the continuity of waves of certain kinds, discreteness is absolutely generated out of them and their interactions, such as separate wave peaks and troughs and crests and verges, and wave interference/interaction. Continuity and discreteness are both not going away.
Light is electromagnetic packets, called radiation, called photons, but not the only kind of radiation. Each of the fundamental interactions is believed to have what are called carrier particles, which carry something between locations to produce the interaction and force through that distance. There are more than the 4 forces that I mentioned, and the carrier particle for gravity is not currently known, perhaps because gravity is unique, but the concept of carrier particles producing the effects of forces through interactions is meaningful I believe. First, something produces carrier particles which separate from it, and they move through spacetime, and hit and interact with other things, which causes effects to both the producer of the carrier particle and that which is interacted with when it hits the other, perhaps like a game of catch. This model is probably not perfect, gravity could be very unique, one of the biggest unsolved problems in physics right now is the incoherence of theories which merge quantum mechanics and gravity. Quantum mechanics explains things at the smallest scales, at the level of individual particles which behave somewhat like waves; and gravity explains things at the largest scales, at the level of things with significant mass. The most difficult problems caused by this incoherence between quantum mechanics and gravity are exemplified by black holes and the big bang, within which very large masses exist within very small 'distances' of each other. There are paradoxes and absolute uncertainties with these things because we cannot literally rewind time to the big bang, and we cannot stay alive or send signals outwards if we go into a black hole. Things simply explode out of the big bang, or fall into the singularity of the black hole. What happens at singularities is anybody's guess.
A field is a mathematical abstraction used by mathematicians and physicists and engineers to understand a system with consistent force fields. It requires measurement to know with any degree of accuracy, but in most systems, it's consistent enough to produce workable and effective structures. It works like this: The spaces which things are said with these mathematical abstractions to exist in have some shape, a topology, and the field is an operation which outputs numbers, such as scalars or packed numbers such as vectors or tensors, which are defined at every point in and/or on that shaped space. These fields can describe many things, such as the gravitational potential or electrical potential (voltage) relative between locations, and the equations for each can be very similar. Things move (change position/location, which is relative to others) with some momentum (mass x velocity), their velocity (vector of rate of change of position/location) changes according to acceleration (rate of change of velocity) and the acceleration is determined by a variety of factors, such as in newtonian (non-relativistic) mechanics wherein acceleration is a simple sum of forces divided by the mass of the accelerating body. There's a lot of complexity and exceptions to newtonian mechanics, but the everyday world operates fairly close to it, with friction and shear forces and tensors to describe things like stresses or spacetime shape attributes like a stress-energy tensor. These things have physical meaning.
How do fields, forces, and interactions relate directly? How are they related to plurality, multiplicity, the many of/in this universe? Some things are unfortunate, some things are unavoidable. Forces and fields are abstractions used to model the tendency of systems to behave in certain ways over time, such as a gravitational field or electric field or magnetic field. Even though electromagnetism is one interaction, mediated by photons, it still produces two fields: electric and magnetic. They call it 'electrostatic force' but it's never exactly static. Color is magical, wavelengths/frequencies are magical. Magnetism is mysterious. The fields and forces, abstractions built by thinking beings to model/simulate Other Things, are built either separately from a 'corresponding' actuality, as computation on some hardware or software or wetware or inscribed/written-on medium, such as paper, trees, tables, skin, glass, etc. Or they are built as themselves, as corresponding to themselves, as not a model or simulation but as something running on its own medium.
The correspondence isn't really existent or actual anyways, it's also mediated by actual things, by our empirical processes that link together models to the things we are intending to model. The actuality is never perfectly modeled, or else I would be lying about quantum mechanics, or talking about something more discrete and unreflective. The interactions which a model uses to carry out its processes are its own, separately from the interactions which relate it to the modeled, and within each and every thing, self-action is also possible, uncertainty and divergence from inertia are possible. This is partly what I mean by reflection, but I also mean reflection through interaction with others. Self-simulation is fundamentally imperfect because it will always cause changes which are new and not part of the simulation. The only perfect simulations can be those which simply are themselves (not really a simulation), or are un-interacting-with-the-modeled/simulated and exactly identical and possibly parallel to the simulated/modeled things. The motion of things due to forces is measured as work, as changes in energy, as the transfer of energy between 'pools' or locations. An orbit involves constant interchange between kinetic energy and gravitational-potential energy. The kinetic energy of the bodies/objects in motion, and the potential energy of their continual interactive-bonds, like chemical bonds.
