Opposites and Field

What is the difference between presence and absence if there is no definite way of defining the properties of the background? On a separate note, the naming of a charge as positive or negative is completely arbitrary, and there is no inherent absence or presence of “charge” in that sense just because the electron has been arbitrarily decided to carry a “negative” charge. Both positive and negative charge carriers carry charge, they just happen to be opposite charges (whatever that means) and cancel each other out when present in equal quantities. Same goes for particles and anti-particles, they’re the exact same thing except in the presence of equal quantities of both, there are no particles. Ok, that’s just for things that have an exact opposite, but that’s not really what the question is asking at all - what about things that don’t have opposites, where the only contrast is the absence of that thing?

What the hell am I talking about? Well, photons, for example, have no anti-particle. The presence of photons indicates the presence of light in an otherwise photon-less background (which is defined as a non-photon saturated.. “space”, I guess). In a dark room I see a beam of light, but what is the difference between seeing a beam of light in a dark room and seeing a dark line in an otherwise light (i.e. photon) saturated room? Seems like a pretty stupid question - obviously in one room there are more particles present (and at the opposite locations) than the other, but what if you just change your definitions such that “particle” actually means “absence of background (i.e., empty space?)” and “background” to mean “absence of particle” (assuming that the background in the second room is completely saturated by photons, which I don’t really know what that means, but anyhow..)?

What about just talking about the universe of a perceiver? So, when you walk into a room with a fan on and you stay there sufficiently long and then you turn the fan off, then suddenly you “hear” silence, which really just means all of a sudden you realize that you were actually in a room where the background was filled with sound waves, and then you sensed the absence of sound waves. When you turn the fan back on, you then hear the fan because the background was the absence (rather than) presence of sound waves. In other words, unless there is a disturbance to the state of the room, you would never know what was present or what was absent, and once there is, it’s only a matter of definition of whether hearing things is a matter of “hearing” or “not hearing”. That is, if we’re only concerned about how things are perceived (which is all we could ever be concerned about anyways), then there should be no difference between saying “when I hear people talk I’m hearing sounds” vs “when I hear people talk I’m hearing silence” depending on your definition of sound and silence. 

So whatever, what relevance does that have to anything at all? Is the background in the above image actually black or white? Keyword being “actually”. This is a trick question, but not really, it’s just a stupid question because what do you mean by “actually”? The question assumes that there exists independently (of perception) an “actual” universe where there are definite truths (which may or may not be true) but in any case is completely meaningless to argue since you CAN’T know the answer. Usually however, there is either more “presence” or more “absence”, and the one of which there is more we call “background”. (So in this case, I guess most people should think the background is white. But again, this is a rather meaningless distinction - black board, white board, who cares? as long as you can read the words.)

So what’s the point? Indeed, what IS the point? Is the presence of meaning only meaningful if we assume an entire universe of meaningless background or is the absence of meaning the only actual meaning that is present in the universe where every infinitesimally small occurrence is incredibly meaningful? More simply put, what does “meaning” mean? Do I really care? Reader - do you feel the official feeling of “trippiness”? Or should I say, the lack thereof, assuming that there is no real reason why some experiences of perception should be categorized as “trippier” just because the other experiences were experienced more regularly? Does anyone know why people are so distinctively unphased by the “usual” when there is clearly just as much of a reason to feel bewildered by what you usually experience as there is to what isn’t usually experienced? Naturally, the subsequent discussion would be of “what does it really mean to be good or bad”, but I leave that to the future and proceed to -

The Higgs field. Standard Model says that this is what gives particles their mass - the “presence” of a ubiquitous field. But if a field is everywhere, what’s the difference between being there and not being there? Seems like a stupid question - charges behave differently in the presence of an electric field - but then what’s the point of supposing the “presence” (i.e., existence, but I don’t know what existence means, we’ll skip that for now) of a “field”. Well, I suppose a field is (obviously) just another mathematical construct, an “interpretation” of “what is there” but then again “what is there” is/can only be what you define (and furthermore believe) to be there, right? What do I know? I need a better understanding of field (theories).
