Space

Of course I've always known that the universe was big, however after we discussed it in class this week I realized how big it was, and it was very overwhelming.

However I also thought it was strange when we talked about how the Universe has a diameter of 10-15 billion light years.  I always thought that the universe was never ending...but this came as a bit of a shock to me.  How could the universe have a limit?  I always depended on it being never ending-that’s what the Universe means to me whenever I think about it.  So to think of the Universe as having a limit is sort of contradictory to what I know.
