I agree that dimensions are challenging to picture at certain points.

but In my mind.. :,)

As people, we do have an easy time of understanding the viewpoint of scale. We can even come close to unbelivable differences in scale.

I spend time observing concepts of a "theory of everything" supposedly where Einstein left off. Twelve years ago I envisioned the multiverse in which some types of universes spawn other univeres through Massive Black Holes, that may or may not create offspring universes of their own. Some of these "offspring" seem to only interact with the parent universes weakly through residual gravity. Picture it like a fractal tree dropping seeds in which some new trees sprout and some do not. Eventually older universes die out.

Since then...

I have gone on to visualize , as we all can, how the very small resembles the very large like an atom with electron orbits and solar systems with planetary orbits. Along the continuem of the very small to the very large there are several apparent breaks in which resemblance between different scales and the "our human life experience" SEEM to break down, as in the quantum scale. I believe this is only an illusion and the fractal laws of organization are still at play but along the lines of our own thought processes or dreaming.

Today we have arrived at string theory in which tiny membranes vibrate in various shapes and frequencies. On the very large fractal scale of size and shape there are membranes of seperate universes which we call 'Branes', Strings begin again to resemble the very large branes of entire universes.

While mathmatics can easily juggle differnt dimensions with different numbers, the human mind can get jumbled. However the human mind can in fact get a hold of these concepts of dimension merely by picturing it as a matter of size/scale as easily as we can magnify a fractal with a computer.

Amos, you once postualted a great fractal attractor of the universe. Getting a hold of that equation would make quite a computer program indeed.
Afterall, life is a self organizing process just as a simple fractal is mathmaticly self organizing.

The Large Hadron Collider is a tool which could help us see a larger picture but is still too weak to create a universe. It is theorized that as little as 23 kilgrams of mass subjected to black hole like pressure is enough for the matter to pinch itself out of our universe/dimension and start expanding into its own seperate space time continum. Voila/Eureka!

Is that new universe real or artificailly man made?
It won't matter to the new universe, it simply 'is' by then.

This idea is great stuff for future ethicists, don't you think?
