The way I have interpenetrated this phenomena without technical jargon is that: Light is basically waves or ripples of the + and - charges of the electromagnetic field which permeates the entire universe. This is very similar to sound rippling through a field of air molecules. These waves can be absorbed by matter via electrons in packets or chunks called photons, this absorption creates heat as it gives the atoms more energy than they had, this is responsible for how things heat up when left in the sun and also for how EM radiation waves are produced in the first place as the atoms release energy or mass when given too much of it. Photons can also be re-emitted in the case of mirrors etc. The absorption of a certain frequencies of light and not others is also what is responsible for color. The atoms release electromagnetic frequency vibrations because the electron and its nucleus oscillate there magnetic and electric fields in sync... one after the other, which creates the fluctuations of waves of the electromagnetic field. These electromagnetic waves or "field distortions" can be channeled through spiritual mediums... just joking, they can be channeled through the pupil into the back of retina and the receptors transfer the ripples of the EM field charges into electro-chemical neural impulses which the brain somehow miraculously forms orders of neural connections which appropriately create a trustworthy conception of external reality. But what's the difference between electric, magnetic and electromagnetic fields? Both the electric & magnetic fields are perpendicular to each other & to the direction in which they are propagating in physical existence. EM waves basically replicates itself from each cycle of the electric field and then unto the magnetic field and then to the electric field and so on like in the picture above, and so this results in what we experience as light, the two fields fluctuating together one after the other. But what creates the fields? Electric fields result from the strength of the charge while magnetic fields result from the motion of the charge, or the current. So every atom has an electrically charged strength and an electrically charged motion. But why do EM fields exist through the universe though? Two electrically charged particles will experience a force due to their charges no matter what the distance is between them, So even if intergalactic space was completely empty (which it isn't) there would still be an EM field because matter exists somewhere in the universe. Is this all accurate? The question I have now are: What creates the positive and negative charges in the EM Field? In other words, Why do electric and magnetic fields vibrate on there own? I thought a field was something static and not moving like air and then sound is impressed into it.
