We are learning only as far as we can see.
We're guessing about the size of the universe. Its just a guess.
We're guessing about whats in an atom. Its a lot of theories.
We seem to relate everything we see to our own life span.
For instance, rocks aren't alive because we can't see them move.
Our lives are too short to observe sun's explode or galaxies expand.
Our lives are too quick to observer lifeforms that evolve quicker than ours.
We are to small to see outside of our universe.
We are to big to see deep inside an atom.
We won't begin to learn about this universe until we are free of our bodies.
Only until we evolve into something like a spirit form, will we have the ability to truely explore this universe.
