>>That's exactly what I'm trying to get at. Assuming the article is correct, then there is not general expansion. There is expansion in only one direction. That would mean that we and the rest of the universe are all heading to the same place. In that case, the furthest galaxies in that direction are moving faster than we are, but we are moving faster than those in the other direction. That's the only way I can think of that would make it appear that the universe is expanding in all directions.

>Well, the article may be a little confusing in this respect. The expansion of the Universe is well established. Any "movement in one direction", as noted in the article would be a small movement, superimposed on the general trend of expansion. So, if the article gives the impression that the Universe is NOT expanding, that part is not correct - or it is confusingly stated.

When you blow up a balloon (especially one of those tube type balloons), it expands, but from the vantage point of the blower, it is expanding in one direction - ie - away from the blower. But from the vantage point of any spot on the balloon itself, it appears to be expanding in all directions.

Perhaps the universe is expanding in only one direction, but from our vantage point, it appears to be expanding in all directions.
