The Future of the Universe

   What will happen to the Universe? Will it last forever or will it end? That question has been around for a long long time. We may still be unable to answer it. But we are at least able to predict certain possiblities. In our current view of the Universe there are 2 possible futures.

One possiblity is that the Universe will come to an end in the opposite of a Big Bang called The Big Crunch. In this kind of Universe there would be enough material to stop the Universe's expansion. The universe would turn around and collpase again. It might even blow up again in another Big Bang.

The other possibility is that we live in an Eternal Universe that will never come to end. The Universe would just continue to expand forever. It would get very cold and dark. Eventually all stars would die and there would be no more starlight in the Universe.
