After getting banned for posting my concerns about light not having a medium, I would like to repost my question in a way that will, hopefully, show that this is a serious question of mine and not some trolling game.

My understanding of energy is that it can only exist as a function of matter. Since all matter seems to be divided into discreet particles, energy seems to transfer between them when they collide OR it seems to exist as a tension between the forces the attract them and the motion keeping them apart when they are orbiting on another.

I cannot think of any way that energy could transfer between particles except collision or attraction. This is why I have trouble imagining light as energy without a medium. Although I wonder if EM force of attraction is somehow related to EM radiation (light) since EM seems to be a means for particles to affect each other without colliding.

I have read people's explanations of photons and why it is foolish to insist on a medium for light, and I am not rejecting those. I am just trying to make sense of the concept of energy with and/or without a medium. This seems like a reasonable fundamental topic to inquire into on this forum, is it not?
