In the late 1920's it was observed that galaxies in virtually all directions were moving apart from us, and/or we from them, at a rate that increases with distance. Implicit within this observation was the fact that there is a mechanism that would have caused this increasing rate of separation. There would have been no reason to suppose that this mechanism was not still operating. Why then was surprise expressed when observation showed that it is indeed still operating and galaxies are still continuing to separate at an increasing rate?
