Universe with a capital U
Why do we use a capital U for the word Universe when most people use a small U? Because there is no reason to believe that this is the only universe which exists. The multiverse theory says that there might be several. So we use a capital U to distinguish our Universe from all the other universes, just as we use a capital G to distinguish the Galaxy we live in, the Milky Way, from all the other galaxies.
