Too many to count! We can't see that far, so we probably won't know in this lifetime. ChaCha!

About Universe
The universe can be defined as the combination of everything that is in existence, encompassing all physical matter and energy that occupy both space and time, as well as space and time within itself. It also consists of the physical laws that govern all of the above. Many ways in which we define the term universe date back to Aristotle, who classified and defined the elements that make up what we consider the universe as a whole, which are matter, form and change.
