The Universe is a bubble in a larger multiverse, or that is one explanation of the creation of the Universe. The multiverse, is contained within the much larger Gigantiverse. This is then inside a Massivelyhugiverse. Un-like the the Gigantiverse the Massivelyhugiverse might not be real. This theory was proven by such well-known and highly-respected scientists as Doctor Strange, the X-Men and the Fantastic Four.
The Universe-bubbles that make up the Gigantiverse are held together with duck tape. This is why space appears black. The stars are gaps where the layers of duck tape fail to properly overlap, allowing light to shine through from the Universe next to ours.
Due to temporal anomalies caused by accidentally mixing Splenda with WD-40 and some funky cheese, the universe imploded in 8374. Because the speed of light is inversely proportional to the rate that the internet travels, we can still see the universe from Earth or on top of a milk crate, even though we no longer are inside the universe. In fact, Japanese scientists had recently discovered that in the coming 69 years the universe will fold itself into a paper crane. However, Chinese scienists dispute this for no reason.
The Universe has actually been destroyed once before, when the awesome gods of Heavy Metal did the most godly awesome concert of all time. This caused the Universe to literally implode because of its raw power.
Because man or woman can possibly question himself or herself (!) about what existed before the universe was created, there will always be room for more drugs and late night highly-scientific "seminars" in dorm rooms. If you don't understand the previous statement, consume more drugs until it becomes clear.
The Universe is shaped like a ham. The ham lattice is what holds the Universe together. The galaxies that we observe in space are made of pineapple slices which surround the universal Ham.
In the classical age, people believed the universe revolved around their feet, and documented it in the "Encyclopedia" (to cycle around one's feet). Now that the true ham shape is known, we are completely rewriting all bovine knowledge into the Uncyclopedia.
Eventually, in the near future, the ham will complete its cooking phase and be ready for consumption, at which time the universe as we know it will cease to exist. The exact method is still controversial, but we note here that cows appear to be harboring some secret information on the subject.
Star Trek is a popular cooking magazine. It shows you everything that can be known about the Universe. It teaches how to properly slice ham, too.
Due to the force of gravity roughly equalling to 5.3MHz, the quantum flux of the optical chasm is reversed leading to a secondary super implosion resulting in emmissions of billions of doubly charged flattened electron beams that caused a universe to appear within a glass bottle. This glass bottle degraded over time, leaving the universe we see today. This is a scientific fact, although there is no actual evidence to support it. The universe is expected to be destroyed by accident in the year 2016, when John Prescott presses a wrong button after a particularly heavy night of drinking.
