There's so much more than we know about; it would be egotistical for us to assume otherwise, right?
That's cool you got to experience something a little mysterious. I and a group of friends saw a very unique astronomical phenomena in the sky that due to having been deep woods camping at the time we could not figure out. Couldn't call anyone (the pre-cellular era), couldn't look anything up..
When we got home, another friend told me that it was probably this supernova that had been visible at the time (the first one that was visible to the naked eye, in fact.. this was in '85), but when I looked at what photos were available, none were nearly as fantastic as how it was visible to us, with swirls and movement and slightly bigger in the sky (in a two-dimensional sense) than the space a full moon represents. It's too bad none of us had a good camera with us (again, the pre-cellular era) because I can only assume that the clean air of the beautiful Ontarian wilderness in which we were located had provided us with a unique opportunity for clearly witnessing the event. Even so, a part of me wonders if what we saw was something entirely other than the supernova that was photographed, and apparently not witnessed by anyone anywhere who happened to have a good camera handy.
I'm content to know that I don't know; the experience still changed my life, in terms of having tactile awareness of how removed we are from a complete understanding of life. How small and adorable we are in our overconfidence.
