OK since we rarely post updates, (like every week or so...) how about this theory thing I've been recently thinking about.
Since there is no real viable proof that the universe is expanding; We are trapped in our sun's gravitational pull and maybe because this we see things outside of the sun's "radius" or "field of pull" move further away; giving the image that things are expanding. Maybe things aren't necessarily expanding. Maybe since the tails in the galaxy are pretty thin, and since they seem to merge maybe that gives the impression the things are expanding. Think about it~
