Is Our Universe Just a Balloon in an Infinite Matrix?

[megacal]

Since we can only see out into space (or back in time is it were) a finite distance,
isn't it possible that our universe balloon is just part of a matrix of "balloons", and that there could be infinitely increasing levels of magnitude larger structures?

And in the opposite direction, couldn't there be smaller particles that make up the Boson et al, which in turn are also made up of smaller particles, etc, etc.?

How do we know what the limits are?

We know the size of the observable universe. It's very big. We do not know the size of the unobservable universe because ... it's unobservable. On the small end there is this unit of measure called the Planck length. It is not possible to see stuff smaller than that, not because of instrument limitations, but, because of the laws of physics.

My intuition tells me it's probably so, since we see order
at every extreme. Things look very chaotic
until we back away and see the "Big Picture".

Perhaps a bubble would be a better analogy than a balloon.

A bubble in a whisp of foam, on the shore of a planet, circling a star in
the spiral arm of a galaxy, in a cluster, on the surface of a bubble, in a whisp of foam...
