Well, that question is not that simple to answer. There would be galaxies which show red-shift and other galxies which would show blue-shift. As the galaxies with blue-shift are likely to be closer to the external viwer, their color might dominate. On the other hand, the gravity of the universe would also cause red-shift. Plus, the extrenal viewer will see the galaxies at different ages than we do. He might see the nearer galaxies at an older age than we do, while the galaxies on the other side on the universe will appear much younger. Depending on how far outside from our universe the viewer is making his observations, he might even see it shortly after or even before the "big bang" (if there was any). At least, he might be able to see the universe in a "hotter" phase than we experience it right now. Best regards, Klaus
