Do the raisins expand in space-time? When an analogy is provided, it's usually intended to simplify a more complex situation to help understand what's going on. But really (and absolutely), no such analogy has any bearing on the universe's forces.
That's why I say we should apply logic to the question of the speed of light and what we can see in the universe.
The frequency shift of light emanating from a moving object proves (to me at least) that the speed of light is fixed.
In the theory of accelerating universe expansion, the logical situation is that somewhere, everything is moving away from us (ignoring local gravity effects) and some galaxies are approaching recession speeds that cannot be measured with existing detection systems. If the universe's expansion is truly accelerating, then the corollary is, that, relative to us as an observer, some galaxies are receditn at a speed faster than light.
A lot of bottoming out still to be done!
