"The Hidden Brane [sic]" is a great radio show.
Picture two planes rotating about two independent (and probably also rotating) axes. Where the two planes intersect you have a line. If there is any substantiality to those planes there will be a little resistance at that line to the motion of those planes. Think of it as similar to the resistance of a net crossing a stream.
As these planes move in space independently of each other they always intersect, and that line of intersection moves around all over the place. Let's call that line a little one-dimensional universe.
I said the planes always intersect, but that's not true. On very rare occasions the planes line up parallel. Despite the fact that the little one-dimensional universe is infinite along its dimension, all of a sudden it ceases to exist. And in an infinitesimally small moment after that little universe puffs out of existence, in a different location, another infinite little universe immediately pops into existence. This new universe went from nothing to infinite in an instant. This new universe is very consistent in its resistance throughout its entire length; at least it is initially. However, over time, that resistance starts to coagulate into lumps of vibrating planer material. Those vibrating lumps exert slightly more resistance than the spaces between them and they start actually bending slightly the line of intersection creating little gravity wells. At some point the continuity is compromised and some of these vibrational lumps come in contact with each other and begin to form clumps. The larger the clumps get, the more resistance they exert against the flow of the rotating planes creating deeper and deeper wells that push more and more of these clumps towards each other. Some of these clumps may get so big that they cannot resist the flow and like water droplets on a pool of oil they eventually break the surface and are lost forever to the miasmic flow of the rotating planes.
Now when those two planes whacked into each other after their moment of parallelism, that line of intersection became observable because the resistance between the two planes at that line created vibrations in that planer material. These vibrations were identical and ubiquitous along the whole definition of this universe. These vibrations would also slowly deteriorate over time as the planer material got more comfortable with the concept of intersection. It's kind of like how if you drop a section of hurricane fence flat-wise onto the surface of a pool you at first get a lot of tiny splashing as the water and the steel meet for the first time. As they get used to each other's presence though the fence continues on its way through the water, still resisted, but less so as it continues sink.
These vibrations, ever-diminishing at a steady rate, clumping up into stuff, eventually form into little one-dimensional people. Those people, steadily getting smaller, start observing the infinite universe in which they exist. They see everything getting smaller at the same rate that they are which results in the distance between everything getting wider (nuclear and electro-magnetic forces keep objects tightly concentrated). It looks to them like everything in both directions is slowly pulling away from them. This perception is compounded by the fact that all their local measuring tools are getting smaller as well. a space that would have been measured as an inch a while ago, now measures a foot using the same ruler. Also light that would have been blue when it was emitted back then now appears red because the ruler measuring the unchanging wave length is smaller than it was when the light was emitted. Unable to imagine themselves and everything else shrinking, they just assumed that their universe was expanding, like marks on a rubber band being stretched.
I hope you've all enjoyed my story of the little one-dimensional universe. Sometimes I wonder if it might work if I scaled it up two dimensions: you know, a three dimensional universe formed by the intersection of two four-dimensional branes rotating about moving axes within a five-dimensional whatever-you-call-a-five-dimensional-void-like-thing. Like so much speculation, I guess we'll never know.
