Is the smallest the largest?

We discovered the atom. Then the subatomic particles, electrons, neutrons, gluons, quarks and many more. Which is the smallest part? Today the new topic is strings. Small vibrating entities bilding up the old school particles. Strings vibrating in different frequencies behave as different particles. And it may be the answer to how a particle can behave as both a particle and a wave - at the same time.
I love this stuff!
But it's not proven. And it's hard to prove.
But if, say in 50 years that we can prove that all particles really are strings wobbling around in X numbers of dimensions. What next? Obvious: What are the strings made of?

Have a thought about this: If we had a bunch of supercomputers and a lot of clever programmers developing true artificial intelligence. If they sat up a virtual world with artificial but intelligent beings in it, some of them scientists. How would they study their world? Would it be possible for them to dig into the fabric of their digital world and come to the conclution that thay are all just digits. And that the show is run by processors and memory chips?

An overheard conversation in VR-SPACE-548:
AI-1: Hey! I just discovered that my body is described by vectors!
AI-2: Cool. What's that?
AI-1: It's a line described by mathematics!
AI-2: Ok. It feels pretty solid to me, so what's it made of?
AI-1: Nothing.
AI-2: But I can see and feel it...
AI-1: Yeah, so what?

Back to our world.
How far can we zoom in? Are the strings just math?
To me, if something takes up space, it's made of something... or?
I think that our univers is far more advanced and elegant than a computer (even in 50 years!). So maybe the univers we are a part of is a computing device. But not with the hard- and software separeted. But mixed in total harmony/efficiency. An eternal equation constantly revolvng. Have you thought about the computations required to handle all the photons bombarding our planet every nanosecond? And it's computed in realtime! Everything in the universe is computed in realtime.(1). All our cells, all the atoms in our cells, all subatomic particles in our atoms. And so on. We are all math. Can we ever look outside or even glimpse the border of computation?

Here's a hunch of mine:
In our univers everything also seems to cycle. A dead leaf becomes soil. A star becomes a black hole that slowly evaporates and contribute to new stars. And there is matter and antimatter consuming each others.
Is it possible that the backside of the strings are worlds? That the small strings really are the big universe - a loop? Is the space in space just the other side of matter?
I sure don't know. But I kind of like the idea.

Have a thought about this mumbo jumbo, and please comment!

(1). well, maybe not.. is a computation taking place a light year from us computed at the same time as one here? Or is it separeted a year? Is the speed of light some kind of clock frequencey?
