1. The problem statement, all variables and given/known data Could you confirm or refute these ideas? 1) All fields start from a point charge. 2) We tend to measure the sum of fields from groups of point charges. 3) The inverse square portion of the field strength of a point charge is based on the geometry of the surface area of a sphere. 4) Ignoring any interferences from the environment, the sum of the strength of a field at a distance of a point charge is equal to the strength of the point charge. QUESTIONS: a) Does a field strength at a distance from a point charge exist because of a force or effect that is *moving* through space from the point through a distance? If so, what is the speed of a field ? or b) Does a field strength at a distance from a point charge exist because of an interaction with a medium in it's direct vicinity which then interacts with a medium in it's vicinity and so on? If so, what would the medium of vacuum consist of? How is it recognized? 2. Relevant equations All inverse square field equations.
