You make a good point. Some people predicted that the universe will slow down it's expansion but not enough to collapse, others said it would collapse, but nobody predicted it was accelerating, the very idea is ridiculous but apparently that's exactly what is happening. In its year end issue the Journal Science says the discovery of an accelerating universe is the most important science story of 1998. If the leading cosmological theory can't find a feature that important it makes me wonder if we really have any idea what the hell is going on. I quote from Science "Cosmologists have become less confident about declaring the fate of the universe hundreds of billions of years hence."
