Yes, good point, clearly space is expanding, and matter is sitting there in space, going along for the ride (with a bit of residual momentum, but not much in the cosmic scheme of things, and presumably it cancels out over large enough distances). However, as far as I know this expansion doesn't in itself cause a force to act on the matter within it, somehow pushing it apart, which was the point at issue. (Or at least it appeared to be - it turned out that the *real* point was dark energy). -- You received this message because you are subscribed to the Google Groups "Everything List" group.
