EM Spectrum - where does it end?

While it seems likely that the cosmic soup is in reality well beyond our comprehension, it's clear nevertheless that our language spells signs for us all the time, as regards the truth of what is. We have a fairly confined vision of the Universe because all we know is built around the electromagnetic spectrum, which has a beginning, to us, and an end. We have no idea how the loop might complete itself because to know that would be to compete with the rules of this dimension. We can't compete with the rules of this dimension, because they are omnipotent as far as this Universe is concerned. Seemingly, we live only in this Universe and relate only to it, because we are three-dimensional beings observing two-dimensional reality.

The key components of the rainbow are red, yellow and blue, which are the elements if you like, their being indivisible. Red and blue make purple, fading straight to the UV end of the spectrum. Red and yellow make orange, blue and yellow make green, and if you're feeling green it's not good. A purple patch is a nice thing to have but when you're blue it's not nice at all and red, well. A red rage or a flaming passion, they're all the same, really, aren't they?

Red and infra red definitely look alike from what we can tell, so we must be on to something there when we assign it to hate or to love. They do say the blood is the life, and there are most definitely times when I'm inclined to agree. What I'm saying here is that what we don't know is often as useful as what we do know, and where radio or gamma end up is anybody's guess, but there's not a lot of it being seen around here, if you know what I mean. Far too much dark energy for anybody's good, really.
