I think it's interesting that everything that makes up all known matter is exactly the same in physical design no matter the size.
Atoms have a center mass with satellites in orbit around it, as do solar systems and even universes.
It seems everything follows this same design.
Are we going to look even closer at atoms and find that they also have atoms?
Does this mean our currently known place in space is actually just one of billions of places just like it, and we just have not been able to see the edge of ours yet? or the edge of the one next to ours.
Some scientist are starting to think this is actually the way all of existence is layed out, because it follows the same pattern.
It is just in hugely varying scales and distances so we don't know it yet for sure.
Man has a pretty bad habit of deciding something is the way we think it is and defending it to the death even when wrong.
Let's see, we do that with science and nature so what else could be untrue and defended to the death anyway?
Hmmm,:D
