      Probably not. In fact, we think that the expansion of the universe is accelerating, i.e. it’s expanding faster and faster. There seems to be a force called “dark energy” doing this, but we don’t really know what it is yet, or if there’s something else causing it.

      We don’t know the answer to this one – maybe in the future sometime?! On the timescales we’re talking here – billions of years, human kind is unlikely to ever know for sure…
