I dont believe that space is infinite...

I lean more toward believing in dimensions.

If you observe carefully, physics is very consistent in the universe.

Our atoms have particles orbiting them and also exhibit attractive forces.

What if our universe is nothing more than than the "liver" of some crazy huge being that lives in the dimension above us... and in the dimension below us, there are whole civilizations living on 50% of the atoms in our bodies.

What if these "galaxies" are actually specialized inside of a huge cell to carry out different functions just like in our cells. Do you really think that we as humans will ever be able to see that big of a picture?

Thats like the civilization on our atoms trying to see us....
