i think of it like this. we know of what it is that we can experience.. and we know not of what we cant. so like a fish in the ocean, who, if he had similiar cognitive abilities as a human, wouldnt know that land even existed, nor anything on land, nor the universe.. so we, as humans, on land are kind of like the fish in that we cant understand whats beyond us because we have no ability to conceive of what it could possibly be. if that makes any sense..

This seems to make the most sense to me. I find it unlikely that we are floating around in a ball. What's the ball in? My way, it doesn't have to be in anything. It's folded in on itself, and one side is the same as the other, because they exist in the same time and space through some physical trickery. We can't really observe the nature of this, because we are a part of the system. So we guess at it.
That makes it all work quite nicely.
And I liked string theory. M theory is even better, though. That one makes more sense, even though string theory was the epitome of elegance. Not that far off of one another, though, in the end.
Cheers,

gil stevens said:i would concur with that assesment.. to an extent. the reason said rock will hit you in the back of the head is due to gravitational forces, a force which we think we understand, but ultimately do not. we do though, interact with it each and every day, so its in the realm of our understanding. as a child i assumed the universe was a ball, most likely from the interaction with our planet, moon, sun, etc all of which are spherical. i agree though, that universe is most likely not a ball. i think in essence its a multi-dimensional configuration of which we could never conceive due to our limitations of only being able to perceive three dimensions. basically in agreement with your view of the universe.
string and M theroy are fascinating from the viewpoint of someone with a casual interest in physics.. i am by no stretch of the imagination a phycist. the problem i have with both is that assumptions are created and then grafted around the theroys to ultimately make them work. the notions of parrell dimensions is not an easy one for the human mind to wrap itself around, but when it does, quite literally all of our perceptions are changed. what i find most impressive about either theroy is the way that "matter" acts at the quantum level in that it pretty much surmises that we have nary a clue as to why things work the way they do. the double slit experiement and the actions of particles vs. light goes against the grain of all that we "know" [or dont know for that matter]
what does it suggest that a particle acts differently when observed? does it mean that none of this exists outside our perceptions? and if so, then what are we perceiving?

Everyone knows the earth is flat, and the sun & planets revolve around the earth.
Therefore, the universe is a half sphere sitting on top of the flat earth.
Imagine it like this: cut a ball in half & set it on your desk.
Done.
