Describe some possible futures for the universe that scientists have come up with. (Sel- The universe will expand but ever-more slowly as time passes. The universe will slow in its expansion and eventually stop forever. The universe is static and has never expanded nor contracted. The universe will expand forever at a much faster rate. The universe will expand, come to a stop, and reverse into a "big crunch." The universe will expand forever at a constant rate.
