The universe is everything that there is. Some people like to think of the universe as a vast container, in which everything that exists resides. However, no one know whether or not this container is infinite in size, or if it has an "outer limits". No one knows for sure, as this question of "is the universe finite or infinite?", has been ask for eges. Many scientists speculate that it expands outward as a balloon and has no end, continuing forever in all directions without any meaning at all. Still,some believe there is a limit and that all the galaxies and stellar objects are contained within a limited universe. This moves out of the realm of science and into the realm of the metaphysics and philosophy, because there is no empirical data to suggest any conclusion as of yet.

 

       Even when you look at the night sky, and see the stars, you are looking out into a very close part of the universe. The stars that you see are such an incredible distance away that it makes you stand awestruck by it all. The blackness yousee is the empty space of the universe: the parts that are not filled with light. However, there may be objects moving in the blackness that have no light shining on them and we can only wonder what else is moving through the space.
