AT this time the links do not seem to be working. But I WILL definitely be following this topic article.
Recently, while looking at some galaxy images, I suddenly realized that ALL of the stars (except for the pictured galaxies) I saw in the images were located very close within our own galaxy rather than randomly dispersed out to and beyond the target galaxies. This allowed me finally realize that there are tremendous voids of presumably empty space between galaxies. That was a rather simple but unexpected personal epiphany for me. Just looking is a pleasant experience, but learning to understand what you are seeing is so much more!
It seems obvious now, but I had never thought about it that way before (I just appreciated the beautiful images) - and I have a technical background and consider myself as sort of a "lay scientist". LoL!
I definitely want to learn more and be able to do some basic calculations to help conceptualize what I am viewing in 3 (or more) dimensions. If this topic continues, I will be referring this topic to other amateur astronomers I know. So please keep it coming!
