Top 10 Mysteries of Outer Space: #3

White Holes

One of Albert Einstein’s greatest accomplishments was the proving, through mathematics, the existence of black holes. From the advances in technology, we now have been able to find several black holes, and believe one to be at the center of our very own Milky Way galaxy. What is astonishing, however, is what Einstein also proved through his equations;  white holes also exist. The exact opposite of black holes, white holes are believed to “spit out” an incredible amount of matter from seemingly nothing. Such an object should  be easy to find, yet none have been. If one was found, it may help us explain other unknown mysteries, such as where the material that made the galaxies came from.
