if that component can be broken down to something smaller and that component broken down to something smaller and so on, and so on, where will it end. If it stops at notingness, than how can we exist.

Suppose you have a permanent magnet that is attached to a mass sitting on a surface. The attraction is strong enough that you can pull the mass via a string attached to the magnet. This is not an "idealized system" - i.e. there is energy lost through friction and air resistance. Yet, you can pull this mass as long and as far as you want without any change in the properties of the magnet. There is energy output from the magnet, since it is supplying the force to pull the mass. But where does it come from? Does this somehow violate the Law of Conservation of Energy?

How is it that two charged particles supply the energy to repel or attract one another without changing their characteristics?

Yes, I know it's the magnetic/electrical fields. And that's generated by the charge. But HOW?

For example, many caucasions are called "white," but no caucasion thinks their skin actually looks white for real. Maybe peach, tan, or something. I am interested in what you actually perceive your skin color to be, especially among those who have a skin tone others sometimes label in English with a color. E.g., reddish for some northern Europeans, brown for some people, black for others.

My bet is that whatever color-label you are called, just as most caucasions called "white" would not actually perceive their skin as in any way white, "red" Irishman would in no way perceive their skin as reddish, "blacks" would in no way perceive their skin as actually black, and so on for "brown" and "yellow". In each case, each person perceives their color to be kind of hard to describe, just as a caucasion might struggle and say peach-ish.

Alternatively, perhaps some of you are, say, called "brown" by others in the racial or ethnic sense, and ALSO truly perceive yourself to be genuinely brown.
